The A429 is a main road in England that runs in a north-northeasterly direction from junction 17 of the M4 motorway (4 miles (6.4 km) north of Chippenham in Wiltshire) to Coventry in the West Midlands.
It links the M4 in Wiltshire to Coventry in the West Midlands, by way of Malmesbury (bypassed), Crudwell, Cirencester, Stow-on-the-Wold, Moreton-in-Marsh, east of Stratford-upon-Avon, Warwick, and Kenilworth.
In the 1990s the dual carriageway between Chippenham and the M4 motorway became part of the extended A350.
Heading northeast, the road meets the Fosse Way near the southwestern outskirts of Cirencester.
Until circa 1937 this junction was some 2.6 miles (4.2 km) further south, near Jackaments Bottom; when RAF Kemble (now Cotswold Airport) was built, the A429 was diverted south of the airfield to follow an upgraded existing road through Kemble village, and the section of the A429 north of the airfield became a continuation of the A433.
