The Highways Agency has gone out to tender for a complex £11M project to strengthen the A14 Huntingdon railway viaduct in Cambridgeshire.
The winning contractor will be required to fabricate and install structural steelwork beams to the underside of the existing viaduct, that carries the A14 dual carriageway trunk road over the East Coast Main Line.
The scope of work also includes design and installation of enabling temporary works, removal of existing steelwork beams, and the installation of headroom traffic warning signs and modifications to the local road. Major constraints include having to work at height above the East Coast Main Line Railway, the proximity of station car parks and a local road. The A14 trunk road, the railway and local facilities are also to have minimal restrictions during the works.
The works are expected to cost between £8.5M and £11M and take 18 months.
