associated engineer
John Smeaton
date  1768 - 1770
UK era  Georgian  |  category  Bridge  |  reference  SK788556
ICE reference number  HEW 1822
The seventy-four Newark Flood Arches carry the A616, once the Great North Road, over the River Trent valley from Newark north west to South Muskham, in an area prone to regular flooding.
Smeaton's Newark Flood Arches are in fact a very long bridge: more than 1.6km long. The brick structure is Grade II listed. Its arches are mostly 3.7m wide, and 1.8m high from foundation level to springer. The passageways through the arches are 10.1m long, across the width of the road. The 74 arches are bunched in eight groups, and the whole was built between 1768 and 1770 at a cost of 12,000.
The road over the arches is bounded by parapet walls with stone copings. There are cutwaters on the piers between arches.
Smeaton designed the bridge so that the crown of the road surface would be approximately 300mm above the level of an extreme flood in this area one of which he observed from a boat in February 1766.
The west side of Newark Flood Arches was widened by 4m in 1929. In 1990, Nottinghamshire County Council replaced some of the fill above the arches with concrete. Smeaton's arches are still all visible on the east side of the bridge.
