The divergence of the A419 and A417
|Length||36 mi (58 km)|
| M4 J15 |
The A419 road is a primary route between Chiseldon near Swindon at junction 15 of the M4 with the A346 road, and Whitminster in Gloucestershire, England near the M5 motorway. The A419 is managed and maintained by a private company, Road Management Group, on behalf of the UK Department for Transport.
From the M4 to Cirencester it is a dual carriageway road, which generally follows the course of the Roman road Ermin Way, but dualling work completed in the late 1990s, and the bypass of Cirencester, has taken it off-course in some places. East of Cirencester the A417 continues straight ahead as the major road and the A419 separates through Cirencester and Stroud, becoming mainly single carriageway. West of Cirencester the road loses its primary status; it crosses the M5 at junction 13 close to a former Little Chef restaurant, then finishes 0.4 miles (0.64 km) further west at a roundabout with the A38.

The bridge is just east of the town and is a concrete construction carrying a dual carriageway, built as part of the two-mile £2.4m Blunsdon-Cricklade Improvement which opened in June 1988.
When it was first designated in 1922, the A419 ran from Hungerford, Berkshire, to Gloucester. Before the war, the section from Cirencester to Gloucester was renumbered the A417, and the A419 was extended from Cirencester to Stroud and then on part of the route of the former A434 through Stonehouse to a junction with the A38 at Hardwicke, just south of Gloucester.
Following the opening of the M4 motorway, the section from Hungerford to Commonhead was downclassified to the B4192. The old lay-bys remain, showing that this was once a major route south. The road was extended south from Commonhead for 0.8 miles (1.3 km) to the M4 on the route of the old A345.
When the M5 motorway was opened, the road was rerouted west of Stroud. A new alignment, known as the Ebley by-pass, was built south of the old route from Cainscross to a point just south of Stonehouse, and from there the road was rerouted on the former line of the A4096 to Eastington, and then to the M5 and the A38 at Whitminster. The old route became the B4008.
The 3-mile (4.8 km) £4m Stratton St. Margaret (Swindon) Bypass opened in October 1977, the 2-mile (3.2 km) £2.4m Blunsdon-Cricklade Improvement opened in June 1988 and the 4-mile (6.4 km) Latton Bypass opened on 24 December 1997.
The major bottleneck in Swindon at Blunsdon traffic lights and the nearby Turnpike roundabout, where local traffic mixes with through traffic for the M4 and the Cotswolds has recently been addressed. Construction of a bypass at Blunsdon commenced on 13 September 2006, and was fully completed in February 2009, although the new dual two-lane carriageway (with an additional crawler lane going southbound up Blunsdon hill) was open by January 2009. A flyover at Commonhead, the main junction for southeast Swindon and another notorious source of congestion, was opened to traffic on 6 February 2007.
