The bridge, which links the Cattle Market car park and the Westway Shopping Centre, will be closed from Monday September 26th to Friday September 30th 2016.
While the bridge is closed, pedestrians are asked to use the nearby Jenson Button footbridge.
Stuart Finney, Group Manager for Neighbourhood Services, at Mendip District Council said: “The footbridge has deteriorated over time so we are going to completely re-deck it and improve the bridge for the many people that use it each day. I would like to apologise in advance for any inconvenience this closure may cause and would ask people to use the nearby Jenson Button bridge while we complete the work.”Call the Mendip District Council contact centre on 0300 303 8588 Monday to Friday 8.30am-5pm for further details.
