Maintenance Scheme

Part of our ongoing programme of work to maintain England's strategic road network

Cost:  Approx.£900,000

Managed by:   Area 2


Where was the project located?

The scheme took place at Winterbourne Lane underbridge continuing to the junction of B4058/B4057 High Street /Beacon Lane in South Gloucestershire.

Why was the scheme needed?

Water was leaking from the top of the bridge deck surface which had caused corrosion to the underside of Winterbourne Lane underbridge.

What work was carried out?

The works addressed the root cause of the leakage by removing the existing central reservation where the water was running through and replaced it with new solid slab cast in-situ barrier. We also carried out new waterproofing. New drainage channels were also installed.

How did this benefit road users?

The scheme will maintain the integrity of the structure and avoid costly repairs at a later date.
