Shops and a footpath in Sheringham in Norfolk, which have been shut for a month because of a sinkhole, are due to re-open this morning.
Anglian Water said the high street had now been made secure. Work to repair the damaged pipe is ongoing.
An Anglian Water spokesperson said, "Following continued excavation on the sink hole in Sheringham High Street the Anglian Water team have made the surrounding area secure which means that we will be able to open the currently closed footpath and shops in the High Street from Wednesday 26th June.
"The excavation of the sink hole will continue, and the team are expecting to reach the damaged pipe by Thursday.
"Once the pipe has been exposed an assessment will take place of the damage caused and have a better estimate on the timescales for the repair will be made."
