Major repair works to two bridges are currently underway in Jarrow. The project will see the structural refurbishment of Albert Road and Kirkstone Avenue bridges, both approximately 2 miles apart.
Located on the A185 and spanning two Nexus metro lines and one Network Rail line, the Albert Road bridge was last refurbished in 1988. The 51-year-old structure will undergo strengthening works, concrete repairs, resurfacing, installation of new bridge joints, replacement parapets and full re-waterproofing of the bridge deck.
The Kirkstone Avenue footbridge spans the A19 south of the Lindisfarne roundabout. The footbridge will be lifted and removed from site to be fully refurbished, repaired and modified before being installed and re-opened later in the project.
On site works at Kirkstone Avenue will include replacement of the parapets as well as raising the level of the bridge above the A19 to enable removal of the existing limited headroom restrictions on the A19 slip roads.
Awarded on a design and build basis, the brief was to provide access that met current design standards and provided an extended lifespan of 60 years.
The works involved the demolition of the existing bridge and the fabrication and fitting of a new bridge with limited access from one side of the river whilst maintaining the travel operations in the SYPTE Bus Interchange below.
The supporting pier foundations were assessed as being suitable to meet current requirements and were retained but required concrete repairs and strengthening works to bring them up to standard. New parapets were also provided to bring them up to the required safety standards.
