PHILADELPHIA (CBS) — A large water main break along the Roosevelt Boulevard was repaired on Tuesday afternoon.

The southbound outer lanes of the Roosevelt Boulevard between Harbison and Tyson Avenues were shut down for several hours Tuesday morning after a water main break.

The lanes were fully re-opened at about 7:45 a.m. The water main break was discovered at about 1 a.m.

Traffic in the southbound inner lanes was never impacted.

The main is eight inches and located under a sidewalk.

Water Department crews were able to turn off the water valve at about 6:45 a.m. Approximately 40 customers were without water service.

After the water was shutoff, crews laid down salt in an attempt to prevent the free-standing water from freezing.

There may be lane closures or restrictions in the late morning or early afternoon, when Water Department crews can begin repairs on the main.

The Fire Department also responded to check hydrants in the area.

Fire Battallion Chief Jim Renninger says, “We come in and make sure there is no basement flooding and there’s adequate water supply for firefighters.”

The water department says water was able to be restored to area residents around 1 p.m. on Tuesday.
