Emergency services were called to tackle a gas leak in Hebburn after a car hit the gas main.
The incident took place on Black Road around 9.10am and police evacuated a small number of houses in the area, but no one was injured.
Black Road and Ralph Street were closed to assist the emergency response, but there was no significant disruption in the area.
A Northumbria Police spokesman said: "Police have been on the scene of a gas leak in South Tyneside this morning after a pipe was hit by a car this morning.
"At around 9.10am this morning police received a report that a car had hit a gas pipe on Black Road in Hebburn.
"As a result police evacuated a small number of properties in the area and closed some roads as engineers repaired the pipe.
"Nobody was injured in the collision and the pipe has now been repaired.
"There have been no concerns for the safety of the public.
"Children at a nearby school were not affected by the incident and officers have been in the area to reassure anyone with concerns.
"Members of the public have been advised to respect the police cordon still in place and speak to local officers if they have any concerns."
A spokeswoman from Northern Gas Networks said their team arrived within 15 minutes and quickly made the situation safe.
The gas supply to one upstairs property has been temporarily turned off in order to allow repair work to take place.
Fergal O’Donovan, Customer Operations Area Manager for Wear said: “Our team were on site very quickly and made the situation safe.
“We will remain on site today until work to replace the service pipe is completed later this evening.”
