Around 200 extra parking spaces will soon be available for motorists visiting Gloucester city centre.
The Barbican site, which has lain unused for a number if years, will shortly be turned into a car park while plans for its longer term future are developed.
The site has temporary planning permission for three years and should be opened to motorists in the early autumn with a mix of contract and pay and display spaces.
Work taking place on the site includes landscaping, drainage and fencing as well as marking out the parking spaces.
Gloucester City Council and Gloucestershire County Council recently signed an agreement looking at the potential development opportunities for the Quayside and Barbican area – which includes the now vacant former prison.
City Council Leader, Paul James, commented: " Major redevelopment projects, as we know, have long gestation periods. It is important, while we work behind the scenes, that this site is not left any longer as a sterile piece of land.
" Its use as a car park will be a useful addition to the parking opportunities available in the centre of the city – and for major events at The Docks. We have a little more work to do before it is ready but we hope that will be early in the autumn."
