A temporary speed limit has been lifted on a new link road.
A 30mph (48.2km/h) limit was put in place when the A30 to St Austell Link Road opened while engineers completed work on and near the 3.9-mile (6.3km) single carriageway, Cornwall Council said.
The road, which connects the A391 at Singlerose Roundabout in Carluddon with the A30 at Victoria, has been built to divert traffic away from villages such as Roche and Bugle.
Steve Trevelyan, councillor for Roche and Bugle, said the road would make a “massive difference” but there had been frustration over how long the work had taken.
In October, Trevelyan said motorists were not using the road because the speed limit and ongoing work meant it was quicker to use the old route through the villages.
The councillor said the road was “brilliant” and long overdue, but there had been “no urgency” to get the work done and temporary speed limit lifted.
“It’s like someone coming round and doing your kitchen and then leaving and saying ‘oh we’ll finish it off’ and it takes forever,” Trevelyan said.
He added he would like to see measures set up in the future to stop similar delays.
Trevelyan said: “I would like to see contracts put in place where there’s time constraints and possibly fines, because it just seemed like ‘we’ll finish it when we can with the few men we’ve got’.”
The BBC has approached the council for comment.
