The Cambourne to Cambridge Public Transport Route is a priority project for the Greater Cambridge Partnership (GCP) and a first phase of Cambridgeshire and Peterborough Combined Authority’s plans for a Cambridgeshire Autonomous Metro (CAM).

A new reliable, public transport route will ease congestion, create sustainable travel choices, connect communities and support growth.


Parts of the current Cambourne to Cambridge road network, in particular the A1303/Madingley Road, suffer heavy traffic congestion at peak times. Without action, by 2031 car trips into the city are set to increase by up to 70%, with already lengthy journey times expected to double.

A new route, bypassing other road traffic, will provide a public transport alternative to avoid congestion and make quicker journeys, with provision for walking and cycling. 

The dedicated route will create reliable transport links, running regular, ‘turn up and go’ services operating to high service standards.

My target is to get in and out of central Cambridge in the fastest possible manner during peak hours - driver and frequent A428 user


Traffic congestion is damaging to the environment, public health and local economy. The Cambourne to Cambridge route will create sustainable travel choices, be served by modern public transport vehicles, designed to limit emissions and pollution, with additional walking and cycling provision.

Local Plans for Cambridge and South Cambridgeshire propose new housing in towns and villages to the west of the city. Between 2011 and 2031, there are a planned additional 8,000 new homes set for development in the Cambourne to Cambridge area and 44,000 new jobs to be created in or around the city.

A new transport link running regular, quality services will provide a vital connection for growing communities to access jobs, services and other opportunities

A three panel image, illustrating the potential impact of growth without transport improvements. First panel: more than 44,000 jobs to be created in or near Cambridge by 2031. Second panel: more than 8,000 homes planned in the Cambourne to Cambridge area alone by 2031, with a further 3,700 planned at St Neots. Third panel: Increasing journey times between Madingley Mulch roundabout and Cambridge, with no action, expected to go from 23 minutes to 45 minutes.


The Cambourne to Cambridge public transport route is a first phase of Cambridgeshire and Peterborough Combined Authority’s plans for a wider, regional metro network – the Cambridgeshire Autonomous Metro (CAM).

The route is made up of three key elements:

  • A public transport route between Cambourne and Cambridge, providing reliable and sustainable services bypassing general traffic congestion.
  • A new Park & Ride site off the A428/A1303.
  • New cycling and walking facilities.

The route is divided into two sections serving the new Park & Ride site:

Phase 1 - from the Madingley Mulch roundabout to Cambridge - a key area of congestion.

Phase 2 – linking the route west of Madingley Mulch roundabout to Bourn Airfield.

From the proposed housing development at Bourn Airfield, the route continues into Cambourne using existing roads.    



June 2019 – Phase 2 consultation findings released.

Key findings

  • 48% respondents indicated an off-road option as their preferred choice for the link between Madingley Mulch roundabout and Bourn Airfield
  • 20% respondents indicated their support for an on-road option that would feature public transport priority lanes
  • 19% respondents indicated their support for an on-road option that would feature junction improvements

For the Park and Ride site options, 63% of respondents indicated they preferred the Scotland Farm site compared with 17% supporting the Waterworks site

Initial consultation during late 2015 proposed six route options and location of a new Park & Ride site in the vicinity of Madingley Mulch roundabout. 

Early 2016 – public consultation response published and made available online.

October 2016 - the GCP’s Executive Board agreed in principle to an off-road segregated route, given the wider economic benefits, and to undertake further work.

Following further planning and technical work, a late 2017/early 18 consultation proposed more detailed plans for three routes between the Madingley Mulch roundabout and Cambridge:

  • A - on-road bus lane option (inbound only)
  • B - on-road tidal bus lane route suggested by local stakeholders
  • C - off-road segregated route.

As well as two Park & Ride sites: Scotland Farm and The Waterworks.

May 2018public consultation response published and available online.

May 2018 – Cambridgeshire and Peterborough Combined Authority requests a pause to work whilst a review considers alignment with the planned Cambridgeshire Autonomous Metro.

October 2018 - a Combined Authority review has concluded that GCP’s work to recommend a preferred, off-road route is robust and identifies the optimal solution for the Cambourne to Cambridge corridor.  

December 2018 - GCP’s Executive Board reviews strategic and technical Phase 1 route assessment, incorporating responses from public consultation, presenting the off-road route as best delivering project objectives and aligning with future CAM proposals. Phase 1 route assessment will continue, taking into account feedback from stakeholders including residents, landowners and businesses. A single, end-to-end link will be presented to the GCP Executive Board as part of an Outline Business Case for decision in autumn 2019.
