Rush hour delays were caused this morning after an Aberdeen road was made one-way due to a suspected gas leak.
Workers have now sealed off Riverside Drive between the Queen Elizabeth Bridge and the roundabout stopping traffic heading south from the city centre.
It comes after SGN staff were forced to close the southbound lane on Great Southern Road near the King George VI roundabout after the leak originally broke out on Tuesday night.
An SGN spokeswoman said: “We’ve been working since last night in Great Southern Road, Aberdeen, near the Great Southern Road/Riverside Drive roundabout, carrying out emergency repair work.
“It’s been necessary to put inside lane closures in place in Great Southern Road and Riverside Drive while we carry out our work.
“In Great Southern Road traffic is able to pass our work area in the outside lanes.
“From 6pm this evening, Riverside Drive will become one way only from the roundabout for traffic heading towards the city centre.
“Traffic heading south from the city centre will not be able to travel via Riverside Drive, which is closed between Queen Elizabeth Bridge and the roundabout.
“There will be a signed diversion in place with an alternative route.”
