Chisholm Trail underpass will be installed later this month

The Newmarket Road underpass, an important link in the Chisholm Trail, will be installed later this month. Following the lifting into place of the Abbey-Chesterton bridge last autumn, this is the next key milestone as work on the transformational walking and cycling route continues.

To enable construction to be carried out safely, the installation of the underpass requires a temporary closure of the section of Newmarket Road around the railway bridge and Leper Chapel. The Greater Cambridge Partnership, who are managing the project, have informed us that this part of Newmarket Road will be closed to all motorists, cyclists and pedestrians between 8pm on Friday 26 March and 6am on Friday 2 April. Unfortunately, as National Cycle Network (NCN) route 51 is also closed along the river owing to work on the new jetty link, this means that there may be significant diversions for some cyclists. Camcycle has produced a map of some of the alternative routes to help you plan your journeys.

Many of the routes shown on the map include quieter roads and off-road sections, but note that those using them proceed at their own risk. If possible, we recommend testing your diversion route before the new closure point is in place. Please note that although we have included the pedestrian route between Ditton Fields and Stourbridge Common using the railway footbridge (with a wheel ramp for cycles), the steps on the bridge are very steep and the Ditton Fields side in particular is currently quite boggy with mud.

What if I’m not travelling by cycle?

• For motor traffic, there will be a signed diversion in place via Barnwell Road and Coldham’s Lane.
• Bus stops will be suspended between Coldham’s Lane junction and Barnwell Road with alternative services in place. For details on the Stagecoach bus services please visit or follow Stagecoach East on Twitter.
• A shuttle bus for pedestrians will pick-up and drop-off each side of the closure point. There will be westbound departures on the hour and 30 minutes past the hour from the Abbey stadium car park and eastbound departures at 15 minutes and 45 minutes past the hour from the Honda Garage opposite Swann’s Road

If you would like to find out more about the arrangements for diversions while the road is closed, the Greater Cambridge Partnership hosted an online webinar on Monday 22 March. Watch the recording here.
