A section of a busy road in Acle has been closed due to a burst water main.
New Road has been closed for emergency repairs near the junction with New Close.
Engineers from Anglian Water are working to fix the issue, with "delays likely".
An alternative route is available via New Road, Old Road, De Carle Smith Road, The Drive, Acle Link Road and the A47.

The closure, which began on Thursday, is expected to last until midnight on November 4.
Anglian Water has confirmed that emergency access will be maintained at all times.
In July, a burst water main in The Street flooded the road and left locals with low water pressure, and in some cases, no water at all.
The road was closed for several days while the infrastructure was repaired.
