LAUREL, Md. -- The Washington Suburban Sanitary Commission hopes to be able to reopen the 8500 block of River Road in Bethesda by Sunday, officials said.
The commuter route has been closed since a 66-inch water main ruptured on Tuesday, flooding the roadway and trapping several motorists.
Four sections of the water main have been replaced, and a fifth is expected to be replaced within two days, according to the WSSC.
The road will remained closed between Bradley Boulevard and Seven Locks Road through Saturday and possibly longer. Detours have been set up in the area.
The cause of the rupture is under investigation, but WSSC officials said there was considerable corrosion where the break occurred.
The cost estimate for the repairs has risen from $510,000 to $1.3 million, WSSC spokesman John White said.
