DALLAS - An underground natural gas leak in Dallas’s West End area forced some road closures and evacuations on Tuesday morning.

What we know:

According to Dallas Fire-Rescue, the leak was reported around 9 a.m. near Ross Avenue and North Market Street. 

A Hazmat team and a crew from Atmos Energy were called to the scene. They discovered a 6 to 8-inch natural gas main that was leaking.

Several roads around North Market Street were blocked off. About 300 people were also evacuated from four buildings, including two commercial and two residential buildings.

Atmos said it has since sealed the gas line. Its crews are still working to make repairs.

Only the area enclosed by N. Record Street/Ross Avenue and Corbin Street/N. Market Street remain closed.

DFR officials said its team began venting the evacuated buildings once the gas was shut off. The evacuations will remain in place until readings inside the building were considered safe.

Dallas Area Rapid Transit service in the West End was also suspended as a safety precaution and because of the repair work.

What we don't know:

The cause of the gas leak is still unknown.
