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 Roads as a proposal have been a long held ambition for the County Council with the growth of Aylesbury bringing forward these 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 November 1st through until December 8th 2017. Please see the consultation summary document for an overview of the responses received. A follow up event will take place in July 2018 and will be published on this website when details become available.
