The completion of the Banwell bypass has been pushed back to Winter 2027 due to essential water main diversion works, North Somerset Council has announced.

The diversions, managed by Bristol Water, are necessary to relocate underground services from the bypass construction area, ensuring future access and maintenance of water services to local properties. These works must be finished before certain aspects of the bypass construction can commence, as the project involves ground improvements including piling.
North Somerset Council and Galliford Try have made good progress on the Banwell bypass and have rearranged programmes where possible to accommodate the water main diversions. Despite these efforts, the overall project completion is now expected in Winter 2027, a delay from the original Summer 2027 estimate.

"Banwell bypass is a project with a 100-year history, set to finally tackle notorious traffic congestion in the narrows of Banwell village. Despite delay we continue to make good progress on site and the century-long wait will soon be over."

Councillor Mike Bell · Leader of North Somerset Council
Councillor Mike Bell, Leader of North Somerset Council, stated: “When it opens, the bypass will also improve road links between Weston-super-Mare and the A38, helping journeys flow smoothly on our wider road network. In addition to solving congestion issues in Banwell, the project includes miles of new walking, cycling and horse-riding track - connecting with the Strawberry line - along with new woodland, wetland and grassland.”
He added: “Banwell bypass is a vital project for our area, laying critical infrastructure for the future, which North Somerset Council is proud to finally deliver.” Further information about the Banwell bypass can be found at n-somerset.gov.uk/banwellbypass.
