V4 Pedestrian Crossings

The Western Expansion Area (WEA) is situated between Crownhill and Stony Stratford.

Once completed it will include 6,550 new homes, employment land, green open spaces and parks, a main street with retail and leisure units and schools. 

Occupation of homes in the Western Expansion Area (Whitehouse and Fairfields) began late in 2015 and is now increasing rapidly.  However there were no safe pedestrian crossing facilities across the grid roads.  A toucan crossing is now in operation between Fairfields and Fullers Slade.  The pedestrian crossing schemes are part of the urgent work to provide safe pedestrian and cyclists crossings in the Western Expansion Area.


Junction 25 Whitehouse Underpass, V4 Watling Street, between Whitehouse and Two Mile Ash

The General Arrangement (PDF, 395KB) plan shows the location of the underpass.

Here is a leaflet (PDF, 1.7MB) explaining in more detail.


Construction works began with the closure of the V4 on the 10 June 2019. A signed diversion is in place for the road and Redway.

Progress Update Summary

There has been a substantial amount of excavation for the utility providers and new ducts have been laid.  Gas, Electric and Western Power Distribution will be working on site for the next 4 weeks.

We have encountered 38 different services during the excavation for the new gas main, far more than would usually be expected. Each utility must be carefully exposed by hand excavation.

Western Power Distribution has completed half of their diversion and a new joint safely installed.

A major construction project, such as this, involves lots of different groups working together. There have already been over 60 different people working on the site to complete works. 

Works happening over the next couple of weeks

  • Continued excavation on the south side
  • Construction of foundations for retaining walls on the north side
