Contractors have received permission from the Washington Department of Fish and Wildlife and the U.S. Army Corps of Engineers to continue driving piles for Pier 4 in the Tacoma Tideflats through Feb. 28.

Pile driving through this extension is expected to occur during standard hours of 7 a.m. to 9 p.m. weekdays and 9 a.m. to 9 p.m. on weekends.

Manson Construction of Seattle began driving the first of 1,241 piles in September to align Pier 4 with an adjacent pier to create one contiguous berth capable of serving two 18,000-TEU container ships at the same time.

After the fish migration season, pile driving will resume mid-July 2017. All pier construction is expected to be completed in 2018 in time for the arrival of new, larger cranes.
