Avonmouth Bridge

The bridge was built with three lanes each way, with full hard shoulders. In 1995–2000, it was widened to four lanes each way, with the result that the hard shoulders are no longer of full width. The bridge was built to allow tall ships to pass underneath. This gave the bridge steep gradients that cause heavy vehicles to slow down, resulting in congestion during rush hour and the summer tourist season: traffic can back up both on the bridge and on the approaches. The construction contract was let to Fairfield-Mabey and commenced in 1969; Fairfield-Mabey placed a sub-contract with Tarmac Civil Engineering for the foundations, piers and deck concreting works.
