1. Countywide road drainage scheme

Scheme Overview

Where: Countywide
When: April 2018 - March 2019
Status: Ongoing
Summary: Since the start of the programme two years ago £1.4 million has been spent on improving 45 sites, and a further £1million has been allocated for 2018-19, an increase of almost £300k on the previous two years. The new drainage schemes will commence in April, and will include up to 35 new sites
Developer: Transport for Buckinghamshire
Contact: 01296 382416

About the project

Following another successful year, Transport for Buckinghamshire (TfB) will be continuing to deliver improvement measures aimed at a more sustainable, long term solutions to drainage problems identified on Buckinghamshire’s road network. During 2017/18, 25 schemes were completed.

Work has been taking place to assess known sites across the county where road surface water and ineffective drainage is an issue, to find ways of reducing, and hopefully removing the problem.  As well as more prompt removal of surface water, TfB have also looked at dealing with ditch capacity, making sure soak ways are sufficient, installing new gully systems and upgrading pipe sizes to increase capacity.

A Capital budget of £1 million has been allocated in 2018/19 for such projects. Identified initially through Local Area Technicians, each treatment site goes through a thorough prioritization process. Local knowledge, safety concerns, site visits, scans and CCTV footage of existing drainage may be taken into account before determining the priority of each site.  A long term solution to the problem is then found, designed and built.  All through this process, local residents and businesses are kept informed.

Work is currently being planned to take place at the following locations (updated 12 July 2018):

  • Stablebridge Road, Aston Clinton - complete

2. Iver traffic and transport study

In Summer 2016,  the County Council commissioned a Traffic and Transport Study covering the villages of Iver, Iver Heath and Richings Park ("the Ivers"). The study provides a comprehensive view of current and future traffic and transport problems in the area, covering HGVs, private cars, public transport and walking/cycling. It also incorporates the expected future impacts of proposed nationally significant infrastructure developments in the area, such as High Speed 2, the Heathrow Express Depot relocation, Western Rail Link to Heathrow, Crossrail and M4 Smart Motorway (amongst others). A well-attended public exhibition was held in July 2016 to incorporate local views into this study – the boards presented and response forms can be found below. 

The first stage of the Iver Traffic and Transport Study is now available below. A follow-up report is also available, which examines the traffic impacts of the experimental closure of Chequers Bridge (Hollow Hill Lane) by Slough Borough Council. High Speed 2 Ltd’s proposals for the relocation of the Heathrow Express Depot include a temporary closure of the bridge during construction and the Western Rail Link to Heathrow project, to be delivered shortly afterwards, proposes that the route is closed permanently. This survey helps give an indication of the impact of these proposals.

The Ivers Members Liaison Group (IMLG), a councillor steering group formed of elected representatives from Buckinghamshire County Council, South Bucks District Council and Iver Parish Council, has recently been formed.  The group will use the recommendations of the traffic study below plus other local knowledge and proposals to drive forward a comprehensive mitigation plan for the Ivers over the coming months. The primary focus of the group is to promote and develop plans for an Iver Relief Road.

Aside from the relief road, the IMLG has discussed other traffic and transport matters including the most appropriate way to invest a Section 106 sustainable transport contribution from Pinewood Studios. A cycleway has been identified as the preferred option for the group and route options are being investigated.

3. Beaconsfield Shared-use Cycleway, Grenfell Road to Ledborough Lane

Scheme Overview

Where: Beaconsfield - Proposed shared-use cycle link between Grenfell Road and Ledborough Lane. Works also Include an on-road section along St. Michaels Green and Caledon Road, to connect with the existing Beaconsfield Cycle Network.
When: Construction currently on hold (TBC)
Status: Statutory Consultation  Period for Cycletrack Conversion Order ended 22 June 2017
Autumn 2017 Consultation Assessment and Review underway Spring 2018 by Bucks CC
Summary: Extension to existing Beaconsfield Cycleway Network, connecting with existing shared-use cycleway at One Tree Lane/Caledon Road, new on-road route along Caledon Road, to St. Michaels Green, and Grenfell Road. An upgrade of the existing footpath will form the proposed off-highway link connecting between Grenfell Road and Ledborough Lane.
Developer:  Transport for Buckinghamshire
Contact: Bucks CC - Growth and Transport Strategy team

About the project

The project is to extend the existing Beaconsfield Cycle Network with the upgrade of the existing footpath to form a new section of off-road, shared use path for cyclists and pedestrians, between Grenfell Road and Ledborough Lane.

However the overall scheme proposals comprises of three parts, as follows;

i) Upgrade of existing footpath, to form new 2.5 metre width Shared-use cycleway footway facility between Grenfell Road and Ledborough Lane,

ii) On-Road cycle route connection to the existing cycleway network, along St. Michaels Green and Caledon Road, to One Tree Lane, denoted by new signs and white cycle symbol markings on the carriageway, but without intermittent white lane line markings, as this will be proposed as an informal cycle route.

iii) Installation of 4 new bike stands, alongside the town council green, adjacent to Waitrose, at Station Parade.

Funding for this project has been secured by Buckinghamshire CC from Sustrans, (the Sustainable Travel charity), and commissioned by Bucks CC Growth and Strategy Team, for Transport for Buckinghamshire to deliver.

The Beaconsfield Cycle Network has been keenly promoted by Beaconsfield Cycle Paths Action Group, (also providers of the cycle stands), and have been working with BCC to encourage use of the Cycleway Network with the local schools.

The Beaconsfield Cycleway Network aims to provide a safe cycle routes for leisure use, commuting and travelling to school, potentially benefitting a vast proportion of the local population. It is hoped that by encouraging more people to use the route, there will be a subsequent decrease in car use locally, causing positive benefits to congestion levels and the environment,


Informal Consultation completed, occurred February - March 2017.

Statutory Consultation completed, occurred from 25 May 2017  to  22  June 2017.

Construction implementation remains on hold,  tbc May 2018

4. National Productivity Investment Fund – Roads

The Autumn Statement 2016 included the announcement of additional funding for improving highway networks – as part of the National Productivity Investment Fund.  The Government announced that it will be investing an additional £1.1 billion in local roads and local transport. Funding will be focused on relieving congestion and delivering important upgrades and must fulfil at least one of the following goals:

i) To ease congestion and provide upgrades on important national, regional and local routes

ii) To unlock economic and job creation opportunities or

iii) To enable delivery of vital new housing

For 2017/18, the Government has announced that it will allocate £2.064m to Buckinghamshire County Council.   This funding will be used to:

  • Improve access to Westcott Venture Park on the A41 helping to unlock this designated Enterprise Zone and unlock economic and job opportunities
  • Deliver highways maintenance on the strategic road network, providing upgrades to important regional and local routes including:

In addition, in Spring 2017, the Department for Transport announced a second round of National Productivity Investment Funding, to support transport schemes which will be delivered within 2018/19 and 2019/20. Unlike the previous bidding, this round of funding is awarded through competitive bidding. Buckinghamshire County Council has submitted two bids to this fund, for the A418 Oxford Road corridor in Aylesbury and the A40 London Road in High Wycombe. The schemes bid for span improvements to highways, public transport and walking and cycling infrastructure. Submitted bids can be accessed below.


5. A40 West Wycombe to Stokenchurch

Update February 15th 2018

On 28 November 2016 The Government announced that capital funding of £175m over four financial years would be made available to local authorities to improve the safety of 50 of the highest risk A roads sections in England. The 50 routes were based on analysis by the Road Safety Foundation.  .

In January 2017,  Buckinghamshire County Council (BCC) was informed that a 9.2km section of the A40, between Stokenchurch (junction M40) and West Wycombe (junction with A4010) had been identified as one of those routes, with 10 KSI (Killed or Seriously Injured) collisions in the 3 year period 2012-14. This was a rise in the previous 3 year period (2009 – 2011) and as a result BCC was invited to bid for funding.

As a result in April 2017 BCC submitted a bid to DfT outlining initial proposals to reduce the risk of KSI collisions along this section of the A40. Further in depth analysis to determine the measures to be considered to prevent the type of collisions that are occurring is currently being carried out.

As part of the application for funding it was a requirement that the bid document was publicised on the BCC website pending an announcement from the DfT regarding the outcome.

However, in anticipation of a successful bid TfB is planning to deliver some minor works this financial year with the majority of improvements, following analysis, consultation and design, taking place later in 2018 into 2019.

Once BCC have been formally advised by DfT on the success of the funding bid TfB will be in a position to commence the relevant communications and consultation.


6. Daws Hill Lane, High Wycombe - removal of speed cushions

Scheme Overview

Where: Daws Hill Lane, High Wycombe
When: Summer 2017

At the present time, the consultation has yet to be completed


Formal consultation on whether the speed humps should be removed on a permanent basis

Developer: Transport for Buckinghamshire
Contact: 01296 382416

About the project

Resurfacing works have been undertaken to make repairs to the carriageway on Daws Hill Lane, this under the Capital Maintenance Program. Several sections of Daws Hill Lane required attention and to be able to make the repairs, it has been necessary to plane out the speed humps which themselves have deteriorated over the years.

Buckinghamshire County Council is in the process of conducting a formal consultation on whether the humps should be removed on a permanent basis and this is a statutory requirement. This includes consulting with District, Parish and County Council officers. As part of the consultation process, the residents in and around Daws Hill Lane have also been asked been asked to provide their opinions on the proposal.

At the present time, the consultation has yet to be completed. This because Transport for Buckinghamshire are waiting for the completion of the developer works to install and switch on the pedestrian crossing on Daws Hill Lane, and includes the resurfacing, lining, communications and lighting elements associated with the crossing. Once this has been done, a safety assessment of Daws Hill Lane will be carried out by the Network Safety Team. Its findings will form part of the consultation response before a recommendation can be made on whether the speeds humps should be removed on a permanent basis.

In the interim period, Transport for Buckinghamshire has carried out a set of speed surveys. The results of the survey will also be used as supplementary information and considered as part of the consultation.

Transport for Buckinghamshire apologise for the delay.

UPDATE: The signalised crossing has today (1st Aug 2017) been commissioned and is now in permanent operation. The Network Safety Team are now in a position to carry out a safety assessment of Daws Hill Lane as part of the consultation process.

7. A412 Uxbridge Road / Black Park Road Junction

Scheme Overview

Where: A412 Uxbridge Road / Black Park Road junction, Wexham
When: Spring / Summer 2018

Consultation stage


Consultation on junction proposals

Developer: Transport for Buckinghamshire
Contact: 01296 382416

About the project

Following a review of injury collisions across the county, the A412 Black Park Road junction has been identified as a priority for safety improvements.  Between 2008 and 2016 there have been 18 reported injury collisions in the immediate vicinity of the A412 and Black Park Road junction. 13 of these collisions involved turning movements at the junction.

A statutory consultation has been carried out between 21st August 2017 to 29th September 2017, which received a total of 73 responses with 34 supporting the original proposals and 39 objecting to the original proposals. It was agreed that an improved design was required to take into account some of the valid points raised and to address concerns to assist in reducing collisions within the available budget.   

Through a design review, the revised proposals are:

  • Ban the right turn out of Black Park Road (as previously consulted).
  • Ban the ‘U’ turn on the A412 for southbound traffic (as previously consulted). Note the U-turn facility on Black Park Road is maintained.
  • Reduce the northbound speed limit on A412 to 50MPH, which includes reducing the northbound lane to a single lane through Black Park Road junction.

These will be implemented by Traffic Regulation Orders, a revised kerbing and island layout and new carriageway road markings.

A link to the proposed revised layout can be found below.

Transport for Buckinghamshire is seeking your views regarding the proposed changes.

Objections must be made in writing, together with the grounds on which those objections are being made. This can be done through:

  • Or in writing to Trevor Bonsor, Transport for Buckinghamshire, Griffin Lane Depot, Corrib industrial Park, Griffin Lane, Aylesbury, HP19 8BP

Please quote A412 / Black Park Road junction in all correspondence.

The deadline for responses is 01/02/2018.

Following the feedback from the consultation a decision will be made by the County Council, which will be published on the Buckinghamshire County Council website.

8. Developing deep learning techniques for semi-automatic detection of road assets in Buckinghamshire

The digital transformation is rapidly changing from the way we travel on our roads and how we provide and maintain our infrastructure. The Department for Transport is launching a competition to help stimulate further transformation and to enhance Britain’s position as a leading transport innovator. Our aim is to help encourage highway authorities to make road transport increasingly smart through the use of data and connectivity to improve safety, efficiency, and emissions.

The competition will provide £500,00 for local authority projects costing between £30,000 £100,000 which will:

  • demonstrate the capability of connected vehicle data;
  • improve the quality of road condition and asset management data;
  • provide the business case for more widespread deployment across a number of highway authorities;
  • enable the development of smart asset strategies based on harvested intelligence; and
  • help support innovation within the private sector supply chain.

Details of our entry

Amongst a number of core issues that relate to Connected Automotive Vehicle Systems (CAV's) is a need for accurate real-world data from which a CAV's inherent spatial location and proximity components can leverage an accurate real-world context. Broadly speaking, these components typically involve Deep-Learning algorithms, drawn from machine learning and neural network technologies, from which a CAV can determine its spatial proximity as accurately as possible. While this technology is showing many positive and promising developments for CAV technology, its effectiveness is significantly determined by its access to appropriate training data that provides a high level of accurately defined real-world contexts.

9. Proposed parking restrictions Cryers Hill Road

Scheme Overview


Cryers Hill Road, Hughenden


Consultation stage



Developer: Transport for Buckinghamshire
Contact: 01296 382416

About the project

Hughenden Parish Council has obtained funding to propose the introduction of parking restrictions on the layby near Great Kingshill School by the village entry gate. This is to address long standing concerns with inappropriate parking in the layby and verges. A formal consultation has taken place on the introduction of restrictions which include;

  • To impose a weight limit of 7.5t at all times on the layby.
  • To make the layby a Pay & Display zone during the hours between 10am-2pm Mon to Fri. A charge will be 50p per hour will apply on the layby during these hours.
  • To impose carriageway and verge clearways south of the layby as shown on the  “extents and types of restriction link” at the bottom of the page

We have designed a scheme which we hope addresses all the concerns and allows for parking at appropriate times. Also, it is planned to introduce a clearway in the bus stop opposite Great Kingshill School which does not require consulting upon.

The consultation has now been completed and the responses concluded that there was a considerable majority support for introducing all the restrictions. An analysis of the consultation results can be viewed by opening the analysis attachment.

The Cabinet Member for Transportation has signed off a Key Decision that allows Transport for Buckinghamshire to progress with introducing the restrictions. We are now in the process of completing the legal requirements and Traffic Regulation Orders that will then make the restrictions enforceable. The orders will then be advertised in the local press and the signs and Pay & Display machine can be installed. Once done, the restrictions will become enforceable and we will update this web-page to provide estimated implementation dates.

On behalf of Transport for Buckinghamshire and Hughenden Parish Council, the Network Improvement Team would like to thank you for time and patience in this matter.

10. Proposed changes to parking in Chesham - phase 2

About the project

Following the completion of parking restrictions in September 2017, there have been significant concerns about parking for Broad Street, Bellingdon Road and Kirtle Road residents.  Due to this, a number of residents have asked for alternative proposals to be developed and the Councils have agreed that the following;

The option for Broad Street:-

  • Allow shared use of the 1 hour waiting bays with resident parking Zone C Monday – Friday 8am-6pm

The option for Wesley Hill:-

  • Allow shared use of the 1 hour waiting bay with resident parking Zone C Monday – Friday 8am-6pm

The option for Kirtle Road:-

  • Provide Restricted parking Zone C Monday – Friday 8am-6pm

Chesham Town Council is undertaking informal consultations to ascertain if there is support for the new proposals and to ensure the formal consultation and implementation proceeds with local agreement.

Update - The consultation is now complete and being collated ready to meet with the working group in September 2018.

11. Improvements to Western Linslade and Stoke Hammond bypasses

Scheme Overview

Where: Western Linslade and Stoke Hammond bypasses
When: August 12 to early October
Status: Work in progress
Summary: Resurfacing work of a five-mile stretch of Stoke Hammond and Western Linslade Bypasses (A4146)
Developer: Transport for Buckinghamshire
Contact: 01296 382416

About the project

Work on resurfacing the five-mile Stoke Hammond and Western Linslade Bypasses (A4146) will start on Monday August 13. The £4.5 million investment in renewing the five-mile dual carriageway surface will take around eight weeks. The work involves removing the entire surface course, which has a number of surface defects, and, in areas where investigations have found structural weakness, replacing some of the lower layers.

How we’re planning to do the work

The northbound (towards Milton Keynes) carriageway will be closed for four weeks from Monday 13 August to allow up to three resurfacing teams uninterrupted access. 

On Monday 10 September, we plan to reopen the newly surfaced northbound carriage, and close the southbound carriageway (towards Wing and Leighton Buzzard) for four weeks to allow work to progress. Both carriageways will close on Sunday 9 September to allow equipment to be moved.

Both carriageways will also close at the weekends of August 17-20 and August 31-September 3 to allow roundabouts to be resurfaced.

We’re aiming to reopen the whole route on Sunday 7 October.

Progress with work will depend on weather conditions. We’ll post updates on this page and also on social media – Twitter @buckscc and @tfbalerts

Traffic diversions

Traffic from the Aylesbury direction on the A418 will divert from the A4146 roundabout at the Wing end of the bypass, via the Leighton Buzzard bypass, A505, and A5 to meet the A4146 again at Kelly's Kitchen roundabout just outside Bletchley.

Traffic from the Milton Keynes and Bletchley directions will divert on to the A5 at Kelly's Kitchen roundabout, via the A505 and Leighton Buzzard bypass to join the A418 at the roundabout near Wing. 

We’ll put diversion signs up on all the approaches to the Stoke Hammond and Western Linslade bypasses. Every effort will be made to minimise delays, but some disruption can be expected.

Works schedule - subject to favourable weather conditions
