Work to Repair the A428 at Madingley and Cambourne

Road works are being carried out to repair the A428 at Madingley and Cambourne.

We are working on behalf of Highways England to repair and maintain the A428 near you. This work will repair the A428 at two sites – the Cambridge Road bridge by Madingley, and the A428 eastbound from the A1198 roundabout at Ermine Street to the entry slip road for Cambourne.

Subject to weather conditions, we plan to start work on the Cambridge Road bridge on Monday 11 April, finishing by July. We will be working between 20:00 and 06:00. To keep road users at a safe distance from the works, we will have lanes closed both east and westbound, though not in both directions at the same time. These closures will be in place 24/7 for the duration of the works, for five weeks in each direction. These lane closures, which will also have a 50mph speed limit in place, will be from Cambridge Road and Madingley to the A1303.

We will close the A428 between the two junctions to install the lane closures. The road will be closed westbound on Monday 11 April and eastbound on Monday 25 April. When the A428 is closed westbound, drivers will take the A14 at junction 31A for the A428 west, then take the A14 to junction 24, the A1198 south to the Caxton Gibbet roundabout, where the diversion ends. When the A428 is closed eastbound, drivers will be diverted off in advance at the Caxton Gibbet roundabout, head north on the A1198 to junction 24 of the A14, the east to junction 31, where the A14 merges with the A428. Drivers missing the pre-divert route will turn around the Madingley roundabout and return to take it.

We plan to complete the surfacing work on the A428 at Cambourne between Tuesday 5 and Thursday 7 April. We will be working between 20:00 and 06:00. To keep road users at a safe distance from the works, we will close the A428 eastbound between these junctions while we are working.

Drivers wishing to travel east on the A428 will be diverted north on the A1198 to the A14 junction 24, then head east on the A14 to junction 32 where they will leave and return west on the A14 to junction 31A, where the A14 becomes the A428. Drivers will continue heading west to Cambourne, where the diversion ends

This may result in slight delays for local road users and through traffic, as well as additional noise in this area while we are working, for which we apologise

Important, please read Details about road works

We would be grateful if you would publicise the works to your parishioners through newsletters and other communications where appropriate. We would advise drivers to allow extra time to complete their journey.

We will do our utmost to complete the works as quickly as possible, avoiding disturbance and keeping noise to a minimum. Once complete, this work will ensure the bridge is safe for drivers and provide a safer road surface to enable smoother journeys.
