The M49 motorway is a small motorway west of Bristol, England, that forms a shortcut between the M5 motorway and the Second Severn Bridge on the M4 motorway. It begins at junction 18a of the M5, and merges with the M4 at junction 22, just before the Second Severn Bridge, cutting journey times for traffic to and from Avonmouth docks, Central and southern Bristol and South West England. Having a 2-way junction with the M4, it also fulfils the dual role of providing a bypass for the busy stretch of the M5 between the Avonmouth Bridge and the M4 in case of accidents, etc. A motorway (in the United Kingdom, Ireland, New Zealand and some Commonwealth nations) is both a type of road and a classification. ...

The motorway was constructed in the mid-1990s at the same time as the bridge. It is unique on the British network for being the only motorway accessible only from other motorways.

While this is more a structural than a logical issue, at junction 5 near Sevenoaks continuing around the M25 requires the driver to follow the slip roads, as the anticlockwise carriageway continues as the M26 to the east (towards the M20) and the clockwise as the A21 towards the south coast.
The distance of the motorway from central London (taken as Charing Cross) varies from approximately 12 miles (20 km) near Potters Bar to 20 miles (32 km) near Byfleet.
Beyond that is the split in height between the Northbound and Southbound carriageways, as the motorway climbs the sides of the hills above the Gordano valley, between Portishead and Clevedon.
