Award outcome

Description

The Tamar Bridge and Torpoint Ferries are jointly owned by Cornwall Council and Plymouth City Council. The two crossings are operated, maintained and improved by the Tamar Bridge and Torpoint Ferry Joint Committee (also known as Tamar Crossings) on behalf of the parent authorities. The Tamar Bridge forms a vital road link on the A38 across the river Tamar estuary connecting the town of Saltash in Cornwall and the city of Plymouth in Devon. The Torpoint Ferries cross the lower reaches of the river Tamar (also known as the Hamoaze) between Torpoint in Cornwall and Devonport in Plymouth. The Tamar bridge was opened in 1961 and at the time of opening was the longest suspension bridge in the UK. It is a conventional suspension bridge with a total length of 642m, a main span of 335m and each side span is 114m. The stiffening truss is approximately 5.5m deep. The road deck level is approximately 35m above the River Tamar. Each main tower and side tower is constructed from concrete. The main towers are approximately 76m tall. On average the bridge carries 45,000 vehicles daily. The bridge was strengthened and widened between 1999 and 2001 increasing the capacity of the bridge from 3 traffic lanes to 4 traffic lanes and adding a dedicated pedestrian and cycle path. Tamar Crossings employ a small in house engineering team that manage bridge inspections, maintenance works and engineering projects.
