J19 → M4 motorway
The M32 is a short motorway in South Gloucestershire and Bristol, England. It provides a fast link from Bristol city centre to the M4 and is part of the Bristol Parkway. At about 4.6 miles (7.4 km), it is one of Britain's shortest motorways. Most of the road has four lanes, though there is a climbing lane for 440 yards (400 m) north of Junction 2, and the short section between Junction 1 and the M4 has six lanes. Because of this, the motorway suffers daily rush hour congestion, which is worsened during school holidays and in the summer months.
The northern end of the M32 is at junction 19 of the M4, near Winterbourne Down. This junction was originally a grade separated roundabout junction, but was modified so that traffic joining the M4 need no longer give way at the roundabout, therefore increasing the freeflow of the junction slightly. However any M4 traffic wishing to U-turn must now do so at junction 1 of the M32. The road then runs south between Filton in the west and Frenchay in the east. After meeting the A4174 at junction 1, it passes to the east of Horfield, Lockleaze and Easton. Junction 2 is located next to Eastville Park, and meets the B4469 which provides access to Horfield. Midway through the junction a 60 mph (97 km/h) speed limit begins. The motorway continues further south and terminates immediately south of junction 3, north of St Paul's. The road continues as the A4032 into the centre of Bristol, with a much lower speed limit of 30 mph (48 km/h).
- M4 Junction 19 to Junction 1 opened in 1966.
- Junctions 1 to 2 opened in 1970.
- Junctions 2 to 3 opened in 1975.
It was originally planned to be a key radial link through to the hub of a network of radial and ring roads within a rectangle encompassing Bristol. Of this three convenient sides were the M4 (north eastern side), the M5 (north western side) and the tidal reaches of the River Avon (south western side), the south eastern side not being defined by landmarks.
A bus lane was constructed in 2008 on the southbound carriageway of the A4032, Newfoundland Way, the short road which links the end of the M32 at Junction 3 with the Cabot Circus development. The lane starts just south of Junction 3, at an offside merge, and runs for 370 yards (340 m), adjacent to the central reservation. It becomes a general running lane for its final 165 yards (151 m) to a signal controlled junction, which is part of the new road layout for Cabot Circus. The hard shoulder and the remaining width of carriageway were rebuilt as two narrowed running lanes for general traffic, and a lower 30 mph (48 km/h) speed limit was imposed on both southbound and northbound carriageways of this section.
Bus only junction
Construction began in 2015 between Junctions 1 and 2, to construct a new bus only junction on the land where the Stapleton Allotments are located adjacent to the M32 and the land next to the Stoke Park estate. It is part of the North Fringe to Hengrove MetroBus rapid transit route package. The construction work involves creating new slip roads, a new road connecting the slip roads with Stoke Lane and the installation of a new bridge over the M32, which will be installed in summer 2016.
