Update: Workers completed their repairs at 3112 Sunset Blvd. at 1:34 a.m. Saturday morning.
According to Jane Galbraith of the LADWP, the road is again ready for Sunday's LA Marathon runners.
The main break was first reported at 3:55 a.m Friday. Ed Pearl, an Angeleno Heights resident, reports seeing crews arrive at the site just before 8 a.m.
LADWP and Bureau of Street Services crews worked together on the job.
One restaurant owner along the busy commercial stretch reported slow business Friday evening, speculating that the traffic may have discouraged customers.
Earlier: Traffic was backed up along Sunset Boulevard in both directions Friday evening as crews worked on a water main break on an 8-inch section of cast iron pipe.
Seepage from the break had caused the street in front of the former La Parilla Restaurant at Westerly Terrace in Silver Lake to buckle Friday morning.
It also took service out for between 20 and 30 nearby customers, according to Joseph Ramallo of the Los Angeles Department of Water and Power.
Workers dug a 8-or-so foot deep hole to repair the main and nearby storm drains.
Depart of Public Works equipment to fill and repave the road was also on hand, waiting for the repairs to be completed.
"Typically, our crews repair the road first," said Ramallo. "Then Public Works finishes the job to a smooth finish a few days to week later."
Crew members said they hoped to have the road repaved by late Friday night, in time for the LA Marathon, early Sunday.
