Update: A11 Babraham to Six Mile Bottom resurfacing

Please see the document below:


From Greater Cambridge Partnership:

Bartlow Road roundabout (Scheme 15, Phase 3)

Work on the new Bartlow roundabout and Dean Cross junction reconfiguration continues to make good progress, with safety improvements targeting known accident cluster sites.

Construction of the new roundabout at Bartlow, and improvements to the Dean Road junction with the A1307, began in May this year.
Phase 1 (temporary road widening) was completed as planned, and work on Phase 2 (the construction of a new roundabout and works to Bartlow Road South) is in progress. We now plan to start work on Phase 3 at the end of September.

Phase 3 road closures

Phase 3 will involve connecting the new roundabout at Bartlow to the existing A1307. To do this, we will need to close the A1307 in both directions between Fourwentways roundabout and Haverhill for two weekends:

  • Saturday 30 September until Monday 2 October (6am - 6am)
  • Saturday 7 October until Monday 9 October (6am - 6am)

As a contingency, we may also need to close the A1307 on the weekend of 14-16 October but hope to complete the works in full the previous weekends.

Outside of the planned weekend closures, and until the carriageway surfacing is finished, it will be necessary for road users to travel on sections of incomplete new surfacing with temporary road markings.

Traffic lights will be in use from 8pm on Friday 29 September and Friday 6 October, to commence construction activities before the full road closure the following mornings.
Signal controlled traffic management will be installed from 9-12 October to complete the remaining carriageway surfacing and road marking. The A1307 will continue to be open to one way traffic overnight, but localised signed diversions of Bartlow Road North and South will be in place.

A map of the diversion route can be found here.

Traffic Management during construction

To avoid diverting large vehicles such as HGVs through small village roads, the diversion uses other available A roads, including the A143 and A11. 

All efforts will be made to keep disruption to a minimum with warning boards and digital signage to be installed on site from Monday 11 September to inform road users of the upcoming closures. All diversion routes are available to view on the CSET 1 website here.

We would like to apologise in advance for any inconvenience these works may cause.
