Finishing touches are being made to Marlow Bridge this week before it is reopened to vehicles on Friday (November 25) at 10am.
These involve three coats of paint to exposed steelwork that structural engineers have been stress-testing, removal of scaffolding around the two bridge towers, and reinstatement of timber work removed for inspection.
Buckinghamshire County Council Chairman Val Letheren and Town Mayor Bob Johnson will be first to drive across the reopened bridge after a ribbon cutting ceremony.
The bridge, with a three-tonne weight limit, has been closed for extensive inspection and stress-testing since a 37-tonne lorry tried to cross it on September 24.
Transport Cabinet Member Mark Shaw said: 'I'm delighted we've been able to open ahead of the Christmas trading, which is good news for everyone. I'm pleased we have the confidence of a thorough structural engineers' report that the bridge is safe to use.'
