The road was originally constructed as a trunk route by the Highways Agency as the second part of a two-phase improvement of the A10 between Ware and Cheshunt. On 29 September 2006 the road was de-trunked,[4] and the viaduct is now the responsibility of Hertfordshire County Council.
Major works
The expansion joints were replaced by the Highways Agency in July 2005.[5]
Improvements to the bridge parapets to bring them up to modern standards were carried out by Hertfordshire Council from July to September 2008.[6]
