The bridge is just east of the town and is a concrete construction carrying a dual carriageway, built as part of the two-mile (3.2 km) £2.4m Blunsdon-Cricklade Improvement which opened in June 1988.

Following the opening of the M4 motorway, the section from Hungerford via Aldbourne and Liddington to Commonhead was downclassified to the B4192.

Around 1971, a junction was created north of Cricklade with the newly built Spine Road (B4696) which runs west through the Cotswold Water Park.

[4] A flyover at Commonhead, the main junction for southeast Swindon and another source of congestion, was opened to traffic in 2007.

Parts of the newly dualled sections of road are surfaced in concrete, which is relatively unusual in the UK.
