Dirt: On the Tacoma side of the bridge project, crews will start removing dirt around the on-ramp from Jackson Avenue to westbound Highway 16.
The dirt will be moved to near the off-ramp from eastbound 16 to Jackson.
About midweek, crews will start building a retaining wall under Jackson Avenue.
Trucks will return to the old War Memorial Park to remove tainted soil and take it to a landfill. Tests have shown levels of arsenic and lead in the dirt on the northern side of the existing bridge. The work will last about two weeks.
Caissons: Crews have excavated down nine feet on the Tacoma side caisson and plan to be done with the round of dredging on Thursday.
A concrete pour is scheduled Wednesday for the Gig Harbor caisson.
Streets: On Saturday, 22nd Avenue Northwest was reopened to traffic. The road had been closed except to local residents since last summer while crews elevated and realigned the roadway.
