Part of a busy commuter route into Bath is likely to be closed until Friday afternoon after it was damaged by a burst water main.
More than 3,000 homes lost supplies after a nine-inch (23cm) pipe fractured on the A36 Lower Bristol Road, near Churchill Bridge, early on Wednesday.
The burst caused significant damage to the road and much of it needs to be dug up to allow access to the pipework.
A Wessex Water spokesman said water had now been restored to all properties.
He earlier said the leak had been isolated and alternative pipes were being used to supply the affected homes and businesses.
Bowsers were set up at different locations in Bath earlier.
The spokesman said they remained in place in Twerton and Oldfield Park "as a precautionary measure".
He added: "Wessex Water apologises for any inconvenience caused and would like to the thank the local community for their patience and understanding while the incident was resolved."
Leaving the city, diversions are taking motorists along Churchill Bridge, Broad Quay, Green Park Road, Midland Bridge Road, and then Pinesway to rejoin the A36.
Those entering the city travel via Midland Bridge Road, Green Park Road, Avon Street, Corn Street, St. James Parade, Broad Quay and then turn left over Churchill Bridge to rejoin the A36.
