A lorry hit the railway bridge at the entrance to the Holmethorpe Industrial Estate on the Redhill and Merstham border on Friday.
The lorry struck the bridge as it travelled from Frenches Road into Trowers Way. The road was closed over the weekend. It is uncertain when it will re-open. Access to the Holmethorpe Industrial Estate is past the Limetree School via New Battlebridge Lane and Ormside Way or via Watercolour.
Metrobus have had to divert their 430 and 435 services via Battlebridge Lane in both directions and are unable to serve the bottom of Nutfield Road, Canalside or Trowers Way.
