The M4 motorway connects the city on an east–west axis from London to West Wales, and the M5 is a north–south west axis from Birmingham to Exeter.
The M49 motorway is a shortcut between the M5 in the south and the M4 Severn Crossing in the west, and the M32 is a spur from the M4 to the city centre.
The Portway connects the M5 to the city centre, and was the most expensive road in Britain when opened in 1926.

As of 2019, Bristol is working on plans for a Clean Air Zone to reduce pollution, which could involve charging the most polluting vehicles to enter the city centre.

Several road-construction plans, including re-routing and improving the South Bristol Ring Road, are supported by the city council.

Private car use is high in the city, leading to traffic congestion costing an estimated £350 million per year.

Bristol allows motorcycles to use most of the city's bus lanes and provides secure, free parking for them.
