The motorway was planned concurrently with the M4 in the 1960s, and construction was complete to
Eastville in northeast Bristol by 1970. The southernmost section was delayed by engineering challenges and industrial action, and did not open until 1975. Since the mid-2000s, there have been plans to use the M32 as part of a

facility which would reduce congestion in Bristol.
Though the M32 has a small traffic flow, it is one of the most congested motorways in the region as it connects a number of key areas. As well as providing one of the few high-quality routes into the centre of Bristol, it is the only significant link from the M4 to the
A4174 Bristol Ring Road. Parts of the M32 are reaching the end of their intended lifespan, leading to reduced speed limits and occasional closures for remedial work. Local residents have criticised the M32, complaining that it has severed communities and has an unacceptable noise level.
Route

The M32 is long. Its northern end is at junction 19 of the M4, near
Winterbourne Down.

History
Construction
The M32 was planned to be a key radial link through to the hub of a network of radial and ring road

facility would be developed next to the M32 to help alleviate congestion in the city centre. The project was expected to create 1,500 parking spaces and cost £191million. In 2015, construction began on a bus-only junction between junctions 1 and 2, on land partly allocated to the Stapleton Allotments and near the Stoke Park estate. The project is part of the North Fringe to Hengrove MetroBus rapid transit route package, and involves creating new slip roads, a connecting route to Stoke Lane and a new bridge over the M32 to be completed by mid-2016. The bridge was lifted into place in June, which required closing the M32 to all traffic.
Traffic
The M32 is a relatively lightly trafficked route compared to neighbouring motorways such as the M4 and M5, yet has still been described in the West of England Combined Authority
The West of England Combined Authority (WECA), branded as the West of England Mayoral Combined Authority, is a combined authority within the West of England combined authority area, consisting of the local authority areas of Bristol, South G ...
's Joint Transport Plan as "by far, the busiest road corridor into Bristol." In 2001, the average daily traffic flow was 40,400 vehicles northbound and 39,900 southbound, while in 2014, the combined flow for both directions averaged 75,000 vehicles. Despite this, the M32 is frequently congested as it is a popular route into the centre of Bristol. During the morning rush hour, queues can tail back onto the motorway from the city centre. In 2014, the Highways Agency reported that the M32 between junctions 1 and 2 was the most unreliable motorway journey along the entire M4 corridor between London and South Wales, with over 56 per cent of journeys taking longer than predicted. The problem is exacerbated whenever there is an incident on the M4 around Bristol, as drivers attempt to use the M32 as a diversion route, creating further traffic and congestion.
The M32 forms a bottleneck

at its northern end as it is the only link between the M4 and the A4174 Bristol Ring Road. In 2015, Chris Skidmore, Member of Parliament for Kingswood, launched the Gateway2Growth campaign, which would see a new road running from the M4 at Emersons Green to the A4174.
Highways England were concerned that the M32, especially its elevated sections, will reach its planned end-of-life around 2020. Urgent works were recommended on the Eastville Viaduct in particular, which had deficient surfacing, barriers and lighting. A speed limit was placed along the viaduct, while surveying work was carried out in 2016 during the Metrobus junction refurbishments.
Community and environment
The M32 has been criticised for severing longstanding links in Bristol. Older residents have claimed that formerly close-knit communities such as Easton have been shut off by the imposing concrete barriers next to the motorway.[ It has been criticised for running through the grounds of Stoke Park, spoiling the local atmosphere and requiring part of the estate including the Duchess Pond to be demolished.
