Avon - Portway
The Portway is a trunk road, approximately 6.5 miles (10.5 km) long, which links central Bristol, England, with its port at Avonmouth. It is part of the A4 road, which was the primary east west highway in Southern England before the construction of the M4 motorway.
Construction of the Portway started in 1919, partly on the line of the Bristol Port and Pier Railway. In 1924, approximately 200 yards (180 m) of newly constructed concrete embankment slid into the river, posing a hazard to navigation and adding 12 months to the duration of the work. The Portway was the most expensive road in Britain when it was opened by the Minister of Transport, Colonel Wilfrid Ashley, in 1926, costing £800,000.
