Major road works into Bournemouth are being put on hold as more freezing conditions are expected.
Work to clear verges and move reptiles away from the A338 began in November.
The works were initially scheduled to resume last week after the Christmas break, but were then delayed due to the icy weather until Monday.
The 6.5-mile (10.5 km) stretch of road between Cooper Dean and Ashley Heath roundabouts will now remain open as normal on Monday.
A decision on when the works will resume will then be taken.
More freezing weather and snowfalls are expected in southern England on Sunday and early next week.
"The county council will look at the weather forecasts again on Monday and make a decision about weather work can re-start once conditions improve, which could be the middle of next week," a spokesperson said.
The verge clearance work is being carried out in preparation for the whole road to be dug up and re-laid in the autumn at a cost of £26m.
Both carriageways have been reduced to single lane traffic while it takes place.
Boscombe beach was even covered in snow during the week
Bournemouth mostly escaped the heavy snowfalls seen last week in the north and west of the county.
Icy roads however have been a major problem.
A number of main roads were shut in Dorset on Wednesday and Thursday, but no road closures were in place by Friday morning.
The university of Bournemouth reopened on Friday after roads became dangerous.
The county council has said it will continue to salt and grit priority roads, access routes to hospitals, fire stations and bus routes, along with secondary roads.
