South East Aylesbury Link Road


Scheme overview


South East Aylesbury – Stoke Mandeville


Complete early 2021


This project will create a link road between the A413 Wendover Road and the B4443 Lower Road. The road will link with the realigned A4010 'Stoke Mandeville Bypass' being delivered as part of the HS2 project. This will form part of the Aylesbury Transport Strategy.


  • consultants have been appointed to take forward the planning application and full business case for the scheme
  • funding has been confirmed through HS2 and the Local Growth fund (via the Buckinghamshire Thames Valley Local Economic Partnership)
  • surveying of land to inform design is underway
  • transport modelling to further inform design is underway
  • the first consultation took place on 1 November 2017
  • refinements to the scheme following this consultation have been completed. The updated design will be presented on the 17 July 2018. Our consultation section below has more details on this

Next Steps:

  • progression of the full business case and planning application
  • work on Environmental Impact Assessment
  • discussions with landowners will continue

About the project

The requirement for the South East Aylesbury Link Road (SEALR) has arisen through the HS2 realignment of the A4010 (Stoke Mandeville bypass). Initial transport modelling has shown that the A4010 realignment causes significant congestion at the Aylesbury gyratory. This Link Road is required to relieve additional congestion the A4010 realignment causes, and improve connectivity around Aylesbury.

The Aylesbury Link Road proposals have been a long held ambition for the County Council, with the growth of Aylesbury now bringing these forward as a necessity.

The SEALR will be accessed by a new roundabout at the junction of B4443 and the A4010 realignment to the south (as shown in below map). To the North the road will be accessed by a new junction with the A413. The key infrastructure on the road will be an overbridge crossing the Aylesbury line, which is funded by HS2 (through an assurance negotiated by the Council).

The first consultation on the SEALR took place from 1 November to 8 December 2017. Please see the consultation summary document for an overview of the responses received.

Changes have been made to the scheme in order to address some of the comments raised during the first consultation period. The new updated scheme was presented at an exhibition event on the 17 July 2018. This design will be taken forward to a full planning application to be submitted in 2019.

Following the exhibition event held on the 17th July 2018, the project team have created some frequently asked questions.
