Improvements to Five Points Roundabout, Iver

Work is taking place on the busy A412 west of the Five Points Roundabout and Wood Lane south in Iver.

The works comprise:

• the signalisation of the roundabout to improve capacity and address existing congestion issues
• significant repairs and upgrades to the existing drainage infrastructure

This work will be completed in phases, with 3 different organisations involved:

• Buckinghamshire Council
• Pinewood Studios
• a statutory services provider

All 3 organisations are working together to co-ordinate the work and carry it out as efficiently as possible to keep the time required to complete it to a minimum.

Our Streetworks Team is working with all 3 organisations to coordinate this planned work and postpone any other roadworks outside of this in the area to keep traffic moving as best they can (unless they are emergency works, which we are unable to stop).

Below you can find out more about what is planned and the timescales for the phases of the work.

This page will be updated as the project progresses.

The first phase will be carried out by Buckinghamshire Highways. Work will take place from 8am to 8pm on weekdays, with these extended hours adopted to complete the work as soon as possible.

Preparatory work including establishing through ground penetrating radar what utilities are already in place in some areas under the road and exactly where they are. This work will take place at the roundabout on Wood Lane, to the south.

Temporary traffic lights will be in use.

Drainage improvement works involving closures of Wood Lane, with a one-way, clockwise system in place for access. Drivers will follow a diversion via the A4007 eastbound, then Bangors Road South southbound (where there will be temporary traffic lights), then B470 High Street and Langley Park Road westbound, then Wood Lane northbound.

View the diversion route on Google Maps.

The remaining work will involve lane closures and a contraflow on the A412. If we complete some weekend working, this may accelerate our programme.

After Buckinghamshire Highways’ work has been completed, contractors on behalf of Pinewood Studios will start on the major improvement works. This includes signalisation of the roundabout, pedestrian and cycle crossings and other associated infrastructure such as street lighting.

Before the works can begin, Pinewood Studios need to undertake seasonal bat surveys in advance of necessary tree removal works. Subject to the outcome of these bat surveys, additional environmental approvals may be required which could impact the start date.

To minimise long term disruption, Buckinghamshire Highways has asked Pinewood Studios to update their highways design. This is to incorporate a power cable route which can be used by a statutory services provider in the future to prevent additional works at the roundabout.

Buckinghamshire Highways and Pinewood Studios need to work with the statutory services provider to develop the detailed design and obtain final approvals.

This work is provisionally scheduled to last until summer 2026.

We will provide updates and progress reports on work at the Five Points Roundabout on this page and our Buckinghamshire Highways social media.
