Extra sailings are planned for the Clinton-to-Mukilteo ferry route during the nighttime closure of Deception Pass Bridge later this month.

The Washington State Department of Transportation made the announcement Friday.

The added runs are intended to accommodate traffic to and from Whidbey Island during a week that may otherwise leave some motorists stranded for hours.

The five overnight closures of the bridge are scheduled to begin Sunday, July 12. The closures are scheduled from 7:30 p.m. to 5:30 a.m.

State Transportation is planning no extra runs on the run between Coupeville and Port Townsend.

Vehicles taking the ferry from Port Townsend to Coupeville after the 5:15 p.m. sailing will not be able to cross the Deception Pass Bridge.

Drivers should plan to use the Clinton/Mukilteo ferry and Interstate 5 as an alternate route to travel north, according to the DOT.

The extra additional trips are as follows:

n Leaving Clinton at 9 p.m., 1:30 a.m., 2:30 a.m. and 3:30 a.m.

n Leaving Mukilteo at 9:30 p.m.,  2 a.m., 3 a.m. and 4 a.m.

Work on the bridge spans is weather dependent and the date could be pushed back because of rain or cool temperatures.

If all goes well, the bridge paving should be done by Friday morning, July 17.

The bridge work is the last portion of a project to repave State Highway 20, from Frostad Road on Whidbey Island to Sharpes Corner on Fidalgo Island.

Contractor crews finished the roadway paving on June 23.
