A large water main break on Sunday caused the closure of State Route 20 in Port Townsend near the ferry terminal.
Around 3 a.m., Police and Public Works responded to the 1800 block of Water Street where the break was reported near the Tides Inn and Suites.
Portions of State Route 20 pavement were raised several inches above the original road bed as pressure from the water pushed up to the surface. When crews first arrived on scene they found water running west down the road. At least one business, The Food Co-op, 414 Kearney Street, had flood damage as water rushed into the building.
The closure affects commuters traveling to the Port Townsend-Coupeville ferry route. Detour routes for ferry traffic have been set up through city streets.
Water to at least a dozen businesses and residents was shut off but was restored by 3:30 p.m.
The Department of Transportation will not have materials available to begin repairing the highway until sometime Monday, according to Claudia Bingham Baker, WSDOT communications manager.
Detours will remain in place until crews determine the road is safe to reopen, which would occur Monday at the earliest.
The cause of the break is under investigation.
