A308

The A308 is a road in England that runs from Sunbury-on-Thames in Surrey to Egham in Surrey. It is approximately 9 miles long and passes through several towns and villages including Staines-upon-Thames and Ashford. The road is a significant transport link in the area, serving both local and commuter traffic.

Historically, the route of the A308 has evolved over time. Parts of it were once part of the Roman road network. In more recent times, it has been subject to improvements and diversions to accommodate growing traffic demands and urban development. The road connects to major arterial routes such as the A30 and the M25 motorway, providing access to wider national networks.

The A308 is predominantly a single carriageway road for most of its length, though some sections are dual carriageway, particularly around Staines. It features a mix of urban and rural environments, with sections passing through residential areas, commercial centres, and green spaces. Traffic congestion can be a factor, especially during peak hours, due to its importance as a commuter route and its proximity to Heathrow Airport. The road also crosses the River Thames at Staines Bridge.
