A370 roadworks


Part of the A370 will be closed overnight next month as part North Somerset Council’s ongoing commitment to maintaining and improving the area’s roads.

Works are due to start on the Long Ashton bypass on the evening of Monday 12 March with a closure scheduled to be in place for seven nights, including at the weekend, and the work due to be completed by the Monday morning.

The overnight closure, which will be from 8pm to 5am, will be between the exit at Cambridge Batch and the roundabout with the South Bristol Link road (A4174 Colliters Way).

“Due to the nature of the works, and the high speeds on this section of road, we will need to close part of the A370 to allow our crews to work safely,” said Cllr Elfan Ap Rees, deputy leader and executive member with responsibility for highways.

“The working hours on site will be overnight between 8pm and 5am in order to minimise disruption on this busy route. Our traffic data shows levels reduce significantly after 8pm before increasing again after 6am.

“We’re using the road closure to carry out multiple other repair and maintenance works on the section of road that is closed, avoiding having to close the road again in the near future for additional separate works and maximising value for money for council taxpayers.”

The works being carried out include:

  • Waterproofing the bridge deck of the bypass
  • Improving signage for the 2+ lane along the A370
  • Carrying out maintenance on street lighting columns
  • Repairs to vehicle restraint systems (crash barriers)
  • Inspections of Highway Assets
  • Cleaning the existing drainage system
  • Litter pick of area
  • Clearing overgrown vegetation.

The diversion route for traffic heading out of Bristol will be via A4174 Colliters Way and the A38 Bridgwater Road. The diversion will then split between HGVs and light traffic. Light traffic will be signed to use Downside Road, Brockley Coombe Road and back onto the A370; HGVs will be advised to follow signs for the M5 South.

The diversion route for light traffic heading towards Bristol will be via the B3130 Clevedon Road, Weston Road, Long Ashton Road and the B3128 Ashton Road.

Signs will be installed at Junction 21 and key locations along the A370 to advise HGVs of the closure, and to seek an alternative route. There will also be signage as traffic leaves the A370 at the point of the closure directing HGVs towards Nailsea and ultimately via the M5.

The cost for all works is £90,000 and this will be carried out by Skanska, the council’s highways contractor.
