About the project
Bidston Moss Viaduct is a 730 metre long box girder bridge carrying road traffic on the M53 over both the A554 roundabout and the Birkenhead to New Brighton railway. It is the main route into the Kingsway Tunnel under the River Mersey and is used by over 50,000 vehicles daily including 3,000 heavy goods vehicles.
The 2 year construction process was complete in the first quarter of 2012. Working with the main contractor Costain, CBUK undertook the steel bridge strengthening works.
