A Western Orbital would provide a fast and reliable bus link near to or on the M11 between major housing sites and the big employment areas avoiding the busy city centre. These employment sites include: Cambridge Biomedical Campus and the West Cambridge site as well as the North West Cambridge site.

The Western Orbital, along with a dedicated bus route from Cambourne to Cambridge, could ensure better bus journeys between Cambourne and Addenbrooke’s, which could take under half an hour on a traffic-free route. 

The Western Orbital project and Local Liaison Forum is currently on hold pending decisions by Highways England on their Roads Investment Strategy. This decision is due in 2019. Currently, a Park & Ride site at M11 Junction 11 is under consideration alongside changes to expand capacity at Trumpington Park & Ride.

A quick and reliable alternative to travel through the City Centre

The benefits of this scheme include:

  • a faster, more frequent reliable alternative to travelling through Cambridge city centre
  • supports the delivery of new homes across South Cambridgeshire
  • supports access to key employment locations and job creation
  • improves local public transport infrastructure

The Western Orbital is an important proposal for a new bus link between Junctions 11 and 13 of the M11 within the Local Transport Plan 2011-2026. This link could be on the M11 or off the M11 to the East or West. These bus links could be combined with various Park & Ride and cycling improvements.

There is significant housing and employment growth around the M11 area including the Cambridge Biomedical Campus, Trumpington Meadows and West Cambridge. A Western Orbital would provide a direct public transport link between these places.

A segregated bus link through the North West Cambridge site and Darwin Green developments is also planned. This would enable journeys, via the guided busway at Orchard Park, toward Cambridge Science and Business Parks and Cambridge North Station, creating an extensive high quality public transport network to the west, north and south west of Cambridge.

For further information on options for this scheme please continue reading.

Further engagement on the Western Orbital is expected in 2018, the form and timing of further consultation is at the direction of the Executive Board.


This project would be considered for funding from any second tranche of monies received from Central Government. 

Frequently asked questions

A.  This scheme is in its early conceptual stages and detailed plans or proposals of cycling improvements on Barton Road are not available. Cycle improvements can take many forms from improving existing paths by resurfacing and/or increasing path width to creating new cycleways, cycle priority and crossing points for both cyclists and pedestrians.

The level of interest and support for cycle improvements to Barton Road – and what form these should take – is one of the elements we would like to gauge through this consultation.  Any cycle improvements would be linked and proportionate to the measures suggested for Junction 12 under the various options.

A.  The existing Trumpington Park & Ride is very busy and will reach capacity shortly. Developments including Trumpington Meadows and Clay Farm will add to congestion at peak times along Trumpington Road, this will get worse if no action is taken.

An additional Park & Ride on County Council optioned land will encourage car drivers to access the City in buses and help to reduce congestion across the Junction and along the route.

A.  We would like your feedback on what facilities you would like to see at any new Park & Ride or Park & Cycle sites. Possibilities could include hire bikes, changing facilities, lockers, Brompton Docks, secure cycle storage and covered racks but have yet to be determined. 

A. Currently, there is no Park & Ride provision at the Barton junction of the M11. Options B, C and D suggest a Park & Cycle or Park & Ride near the junction in order to improve travel options from those living to the west and south west of Cambridge. No land has yet been identified for a site, and any decision on location would be subject landowner agreements and the decision of the City deal Executive Board. 

We are currently assessing the demand for parking and cycle facilities, which new P&R would generate. We need to consider not only current demand but also allow for future growth in demand.

A.  Creating an ‘Orbital’ bus (and possibly also cycle) link would encourage sustainable travel and offer an alternative to travelling through the busy city centre. Partially or fully segregated bus links would enable consistent journey times and deliver timetable reliability. Without bus priority measures, services get caught up in traffic congestion, become delayed and are less reliable.

A 'Western Orbital’ between Junctions 11 (Trumpington) and Junction 13 (Madingley Road) would enable travel between large housing developments such as Cambourne and Bourn Airfield and major employment sites as well as connecting to the Busway in the south at Trumpington Park & Ride and a bus route in the north at Orchard Park via the North West Cambridge site and NIAB/Darwin Green.
