SAN DIEGO — A 106-year-old water main ruptured underneath a busy Hillcrest thoroughfare Tuesday afternoon, flooding the street and adjacent businesses.
The failed cast-iron pipe began inundating the 3600 block of Fifth Avenue about 3 p.m. Witnesses reported that the roadway was soon beginning to cave in, creating a sinkhole.
Repair workers had the overflow under control by shortly after 4 p.m., said Arian Collins, a spokesman for the San Diego Water Department.
The mishap flooded some nearby commercial structures, forced the closure of two blocks of Fifth Avenue and left five blocks of the north-south boulevard without functional plumbing, according to Collins.
Full repairs to the 20-inch-diameter water main — installed in 1907 — and the roadway were expected to be complete sometime Wednesday afternoon, he said.
