More cracks have been found in a broken Maryland water main which burst last week stranding commuters on a busy road into Washington, D.C., and the road may not open until the middle of the week.
Washington Suburban Sanitary Commission officials said River Road in Bethesda, Md., will remain closed following last week's water main burst which sent millions of gallons of water rushing down the road and forced the rescue of about a dozen motorists.

WSSC spokesman John White said the best estimate for reopening the busy commuter artery is the middle of next week.
It is too early to know the exact cause of last Tuesday's break, but WSSC said there was "considerable corrosion of the pipe" where the break occurred.
Engineers said two other 16-foot sections of the 5 1/2-foot diameter pipe showed cracks and must also be replaced.
