Traffic is now using the new bridge over the canal at Wallbridge.
Surfacing was carried out throughout the nights of Monday, Tuesday and Wednesday.
This allowed the traffic to begin using the new roadway at 3am on Thursday morning.
The road immediatly in front of Bell House, formerly The Bell Hotel simultaneously reverted to a cul de sac.
Gloucestershire Highway's project manager Nigel Edgeworth commented, "We shall monitor the traffic flows on the new layout for a month and are eager to hear what the people think.
Many people who feared the changes during the bridge build have told us that they prefer the system that gives easy access onto Dr. Newtons Way."
The bridge will shortly be officially named as Stroud Brewery Bridge. The whole site will be tidied up over the next few weeks.
