Update at 4:35 p.m. — The leak has been stopped. Police are reportedly preparing to reopen the southbound lanes of Glebe Road.

Update at 3:55 p.m. — From Arlington Alerts: “Both north and southbound Glebe Rd will be closed between N. Pershing Dr and N. Piedmont St through evening rush hour due to an outside gas leak. Please Avoid traveling in the area if possible.”

All lanes of Glebe Road are closed near N. Pershing Drive due to a gas main rupture.

Traffic is backed up in the area as police redirect traffic. Crews from Washington Gas are on the scene digging up part of Glebe Road in an effort to repair what’s said to be a 3 inch gas line.

Arlington County says Glebe Road is expected to remain closed for an “extended time” — possibly several more hours.

This is the second time this month that Glebe Road has been closed due to a gas leak. On Jan. 6 the busy commuter artery was closed for part of the evening rush hour after contruction crews accidentally ruptured a gas line at Glebe Road and N. Piedmont Street, two blocks away from today’s incident.
