After a delay, a major construction project is slated to begin at the north-end ferry dock next week.

Cars will line up differently during the yearlong project, and officials believe the construction could cause ferry delays, particularly during busy times.

When construction begins, vehicles will no longer queue up on the dock. Instead, traffic bound for Fauntleroy will line up starting on Vashon Highway, and Southworth traffic will line up on 103rd Avenue S.W., which will become a one-way street. Buses and ADA vehicles can still unload at the end of the dock, but there will be no drop-off or pick-up area.

In addition, Southworth-bound vehicles longer than 38 feet will be limited to six sailings a day.

In response to feedback from ferry riders, Washington State Ferries will install signs along the highway that estimate what place in line cars in that location are. WSF spokesman Ian Sterling said the signs should give drivers an idea of whether they’ll make the next boat.

While ferries will still unload two lines of cars at a time during the construction, it won’t be possible to load one boat while unloading another. To help keep boats on time, WSF tweaked the regular schedule, changing some sailings by 5 minutes to try to accommodate loading and unloading.

State officials say the 1950s-ear dock needs renovation in order to make it more earthquake resistant. Workers will build large braces at 10 spots along the dock and will replace 200 feet of wooden pilings with steel ones. The $15 million project is funded by federal grants and state dollars.

Construction was originally slated to begin in June, but the state was held up getting the proper permits and securing a contractor. Sterling said WSF still expects the project to finish in June of 2016.
