Water main break shuts down busy Mira Mesa street

SAN DIEGO (KUSI) – A water main break flooded an intersection in the Mira Mesa area and prompted authorities to shut down a stretch of a busy roadway during Wednesday morning’s commute.

The rupture at the intersection of Black Mountain and Mercy roads was reported shortly after 6 a.m., and a SigAlert was issued about 20 minutes later, San Diego police Officer Frank Cali said. Southbound Black Mountain Road was closed to all traffic, including pedestrians and bicyclists, at Park Village Road.

Northbound Black Mountain Road was closed at Mercy Road, according to the officer. Cali said the closure would likely remain in place until about 9 a.m.
