A1 Allerdene Bridge northbound refurbishment works
Part of our ongoing programme of work to maintain England's strategic road network
Where was the project located?
Allerdene Bridge is on the Gateshead/Team Valley section of the A1 over the East Coast Main Line.
Why was the scheme needed?
Back in summer 2009, we carried out work on the southbound carriageway to repair the corroded bridge beck reinforcement and to rewaterproof the bridge. The damage was found to be extensive, but was thought initially to be confined to the southbound side of the bridge. However during the repairs it was discovered that the edge of the adjacent deck, the northbound side, was also beginning to show similar signs of deterioration. It was decided that similar repairs would be required on the northbound carriageway.
What work was carried out?
The scheme involved the following works: -
- Installation of traffic management to allow the works to the northbound deck of the bridge to be carried out safely utilising day time lane closures and night time carriageway closures.
- The removal of surfacing and waterproofing
- Carrying out any repairs required to the concrete deck (including replacement of corroded reinforcement where necessary
- Replacement of waterproofing
- Installation of bridge deck drainage
- Replacement of bridge expansion joints
- Resurfacing of northbound carriageway
- Reinstatement of road markings and studs
How did this benefit road users?
The successful completion of this essential maintenance has extended the working life of this important asset.
