Work has begun on a park-and-ride service for Truro in Cornwall.
The £5m car park, near Threemilestone on the western side of Truro, will have parking for about 1,200 cars and is due to open in mid-2008.
It is the first phase of the city's planned park-and-ride strategy, with more sites planned for east and south Truro in the future.
Councillors gave the scheme the go-ahead in July after successful trials in recent summers.
The buses will leave every 10 minutes during busy periods with stops at the Royal Cornwall Hospital, County Hall and the city centre.
It is hoped the scheme will help ease congestion on Truro's busy A390.
About 6,500 people travel to work each day along the route causing severe congestion.
