Chisholm Trail


To allow the Chisholm Trail to link from Ditton Meadows to Coldhams Common an underpass will need to be installed below Newmarket Road. To do this work safely Newmarket Road will need to temporarily close to traffic.

While some of these closures will be overnight, Newmarket Road will be closed to all traffic, including pedestrians and cyclists, for a week between 8pm on Friday 26 March and 6am Friday 2 April.

Diversion routes

For Motor Traffic: - Signed diversion routes will be in place for motor traffic while the road is closed.

For Bus Users: - Buses that currently use Newmarket Road will be diverted. The bus stops on Newmarket Road between Coldhams Lane Junction and the McDonalds roundabout will be temporarily suspended with no service. Bus operators will advise of changes to their services nearer the time. For details on Stagecoach bus services please visit or follow the operator on Twitter @stagecoach_east.

For Cyclists and Pedestrians: - There will be a separate, signed diversion route for cyclists and pedestrians across Coldhams Common. For pedestrians who are unable to use the diversion route there will be a free of charge shuttle service available from one side of the closure to the other. We are currently finalising arrangements to ensure this service is COVID-safe. Once we have confirmed the details they will be available at

Newmarket Rd Diversions 2021


The Chisholm Trail is an exciting new walking and cycling route, creating a mostly off-road and traffic-free route between Cambridge Station and the new Cambridge North Station. It will link to Addenbrooke’s Hospital and the Biomedical Campus in the south and to the business and science parks in the north.   In all the full trail provides a 26 kilometre route from Trumpington and Addenbrookes  to St Ives.  The central section from Cambridge central train station to Cambridge North train station, which this project deals with, is a 3.5 kilometre route.

The north-to-south, route which closely follows the railway line, provides a quicker and safer route across Cambridge. It would be largely off-road or along quiet streets, avoiding busy junctions and would link up green spaces in Cambridge including: Coldham’s Common, the Leper Chapel Meadows and Barnwell Lake area, with Ditton Meadows (as well as Stourbridge Common beyond).

Contracts were awarded  to Tarmac for construction of both the Greater Cambridge Partnership's Chisholm Trail foot and cycleway (Phase 1) and the Cambridgeshire County Council funded Abbey-Chesterton Bridge last last year.

A start of works ceremony was held on 8 March 2019 on Ditton Meadows. Temporary metal fencing now encloses the areas of work on Ditton Meadows and a site office has been constructed off Ditton Walk. Works to date include the creation of a 350m 'haul road' to the bridge construction area.

Phase One covers the area from Cambridge North Station to Coldhams Lane and links up green spaces in the north of the city creating an off-road route between Stourbridge Common, Ditton Meadows, the Leper Chapel, Barnwell Lakes and Coldhams Common.

The map (above right) is a representation of the proposed walking and cycling route including possible access points. The off-road sections are shown in orange and the on-road sections are shown in purple.

The Trail would make it easier for students cycling to Cambridge Regional College, for commuters arriving at the planned Cambridge North Station to walk to workplaces south of the river and for workers to travel between the Science Park, Business Park, Addenbrooke’s and the Biomedical Campus. It also links to leisure facilities like Cambridge Leisure Park and Abbey Pool.

Updates on the project are available via subscription to the the Greater Cambridge Partnership's e-news bulletins and emails.

A Local Liaison Forum (LLF) has been set up for this project to provide  dialogue between the project team and members of the local community. The Forum enables local communities to keep up to date and to have their say outside of formal consultation processes. The LLFs are open to the public.


The scheme will benefit residents, students and commuters by improving access to key locations and easing congestion on these routes

  • Cutting Congestion
  • Quick, direct route linking major employment and railway stations
  • Quiet, mostly motor traffic-free routes
  • Opens up currently private green spaces to the public
  • Makes cycling a more attractive way to get to work
  • Provides major health benefits
