A gas leak has prompted an emergency road closure in Diss after locals noticed a chemical smell in the area.
Sunnyside in Diss has now been closed by Cadent following the leak.
The road will remain closed for utility repair and maintenance work until further notice.
A spokesman for Cadent said: "A temporary road closure was put in place in Sunnyside, Diss, on Tuesday, May 30, following a report of a gas leak.
"Our engineers will be working to repair the pipe as quickly as possible but until the source of the leak is identified, we are unable to confirm how long the road will need to be closed.
"Please be assured that we will be doing everything we can to keep disruption to a minimum and get the repair completed in a timely manner."
A diversion has been put in place via Shelfanger Road, Saint Nicholas Street and Mount Street.
