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.
Extension of Existing Road Closure including Calverton Lane for Construction of Roundabout, Signalised Junction and Major Sewer Works
The V4 road closure is being extended, allowing Anglian Water to lay a water pipe from the new underpass at Barrosa Way to Crownhill Roundabout, providing necessary facilities to the expansion area. The road closure will be extended up to Kiln Farm Roundabout to facilitate additional development works. By coordinating works we will prevent future road closures in the area and minimise disruption to residents and network users.
The extended road closure starts on 27th January 2020 to 29th May 2020. This extension is required for major works on Watling Street and Calverton Lane for the Western Expansion Area development. The diversion route will be revised to include the extended closure.
The works consist of the following:
- Junction 3 and Calverton Lane Diversion (PDF, 2.2MB) – Removal of existing roundabouts and construction of 1 new roundabout including permanent diversion of Calverton Lane. Sewer diversions, new street lights, updated direction signs, carriageway resurfacing and speed limit reduction to 40mph.
- Junction 26 Signalised Junction (PDF, 2.2MB) – Construction of new access into Whitehouse opposite The High Street. Installation of 4 way traffic signals and redway crossing points. Sewer diversions, new street lights, relocation of bus stops, updated direction signs, carriageway resurfacing and speed limit reduction to 40mph.
The diversion for the Watling Street Extension will follow Millers Way H2, Great Monks Street V5 and Dansteed Way H4.
The Calverton Lane diversion will be through The Wealds towards Stony Stratford and down Watling Street V4 until it meets Millers Way H2.
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
- Installation of the final wall units on the North West arm of the underpass
- Placing formwork and reinforcement for the concrete heels at the base of the retaining walls
See our Frequently Asked Questions page for further information.
A series of four roadshows were held in the local area between 27 June and 6 July. We engaged with 470 people who asked a wide variety of questions. We are adding responses to many of these to our Frequently Asked Questions page.
