A well-used stretch of road faces having single-file traffic flow for up to 18 months due to major engineering works.

The Westley Rail Bridge in Newmarket Road, Bury St Edmunds will be restricted to just one lane across the bridge, with the use of traffic lights, from Thursday.

It is the latest traffic measure to be implemented on the bridge since the county council completed a structural assessment on it in May.

he assessment identified ‘structural deficiencies’ on parts of the bridge, while further examination has revealed another area where the bridge could need strengthening.

The 7.5 tonne weight limit currently in place on the bridge will be lifted, but safety barriers will be installed.

There will be night closures on the road tonight before traffic lights come into effect from 6am tomorrow.

Suffolk County councillor Graham Newman said: “These works are needed to improve the safety of the bridge, and lifting the weight restriction will help ease traffic flow in the area.”
