The Agency has advised road users of changes to the layout of the A46 as part of the ongoing Newark to Widmerpool improvement project.
Traffic will switch on to a 3.5 mile section of the new northbound carriageway allowing contractors to excavate what will become the new A46 southbound carriageway.
The Inholms Road at Flintham will then be closed for up to eight weeks to enable the eastern link road on to the A46 to be constructed.
During this time there will be a signed diversion route in place via Elston and Shelton.
Geoff Bethel, senior project manager for the Highways Agency said: “This is the fifth major traffic switch on the project and takes us another step closer to completing the scheme.
“We are pleased to report work is progressing well and we’d like to thank road users, residents and landowners for their continued patience during all the changes.”
It is the latest stage of the project by contractors led by Balfour Beatty.
It has seen a new railway bridge installed within 83.5 hours, as part of the Highways Agency’s A46 Newark to Widmerpool improvement in Nottinghamshire.
The new A46 needs to go under the existing railway line at Bingham, so the new bridge, designed by URS/Scott Wilson, was provided to take the railway over the road.
The 1300-tonne bridge was then jacked onto two hydraulic platforms, each one with 75 wheels, and raised up.
It was driven into position at a speed of around one mile an hour, lowered onto the six concrete columns and fixed into place. The railway line was re-opened shortly afterwards.
