After years of campaigning and months of construction delays the new A11 bypass between Fiveways roundabout and Thetford will be opened on Monday.
The new bypass will run with one lane open in each direction, and with a 40mph speed limit, between Chalk Hall Farm to near the end of the scheme, just before Thetford roundabout.
Subject to weather conditions all traffic will use the new by-pass from 6am on Monday.
MP for West Suffolk, Matthew Hancock, said: “This is fantastic news for Suffolk. The Highway Agency has made great progress in such a short time and I am excited that the bypass will be opening this quickly.
“Although there will only be one lane at 40 mph to start with, I’m sure it will make a real difference to the local residents as it marks the beginning of a major project for safer and less congested journeys in Suffolk.”
Once the bypass is opened, work will begin to construct the new southbound slip road less than a mile south of the Thetford roundabout. This work is expected to take approximately 12 weeks.
Highways Agency project manager, Geoff Chatfield, said: “Work on the A11 dualling and improvement scheme is progressing well, and with the opening of the A11 bypass we have reached a key milestone.
“This opening brings us one step closer to delivering smoother, faster journeys along and around the A11 in Suffolk. We have worked closely with local partners to ensure disruption to road users during the closures is kept to a minimum.
“Although this is just a partial opening with one lane in each direction with a 40mph speed limit for the time being, road users and local residents will see an immediate benefit of reduced congestion and smoother journeys.”
