There is a water main break in Danbury. The state contractor working on the North Street expansion project hit the main, flooding the exit 6 on ramp. Mayor Mark Boughton says the break has sent millions of gallons of water into the street. The break happened shortly before noon. The repair is expected to take 6 to 8 hours. This is the second time in recent months that the contractor has struck a water main in the project area.
