From June 2020, Mill Road Bridge in Cambridge has been temporarily closed to all vehicles except buses, cycles and pedestrians. We put this measure in place, which acts like the bus gates in Cambridge city centre, under an Experimental Traffic Regulation Order (ETRO). It enables us to make changes to road layouts quickly and amend as needed in response to the Covid-19 pandemic.

We intend for the changes to this busy high street to help people social distance and encourage locals to travel actively by bike or on foot. The measures are funded by the Emergency Active Travel Fund, a Government grant to promote active travel during the current public health crisis.

Whilst the whole of Mill Road remains accessible to motorists, these trial measures mean they can no longer travel over the bridge. We enforce the bridge closure with Automatic Number Plate Recognition (ANPR) cameras. Those motorists who cross the bridge despite warnings will incur a fine. We have installed over 20 signs along Mill Road and on nearby streets to warn drivers about the new road layout. We invest all money received from fines in frontline highway works such as fixing potholes or improving road safety.

You can find out more information about fines on our bus gate page.

Separate to the trial bridge road closure and like other local high streets, we have put white and red 'build outs' at locations along Mill Road to extend the footway and help people social distance when walking along the high street.


We invite comments on the closure of Mill Road Bridge to all vehicles except buses, cycles and pedestrians. Please send your comments by email to The first six months of the Experimental Traffic Regulation Order (ETRO) are the consultation stage during which we record all feedback.

A survey runs between 12 noon on Monday 9 November until 23:59 on 24 December 2020 to offer an additional opportunity for people to have their say on the changes and their impact on Mill Road.

We will collate all feedback, whether from emails, letters or the survey and present it to the Highways and Transport Committee when they make their decision on whether to continue the trial, make the changes permanent or to re-open the bridge to motorists.
