1:00pm | Lane closures along Harbor Plaza in the Port of Long Beach are set to begin the night of Monday, March 19, as crews replace a primary water pipeline underneath the roadway near the Port’s Administration Building.

The project will take about three months to complete. The work will begin with an overnight closure of southeast-bound Harbor Plaza to put in traffic controls from Pico Avenue to Harbor Scenic Drive. Starting at 8:00pm Monday, March 19, the southeast-bound half of Harbor Plaza will be closed, as will the Harbor Plaza East off-ramp from Harbor Scenic. By 6:00am, Tuesday, March 20, the opposite side of Harbor Plaza — which normally takes only northwest-bound traffic – will become a temporary two-way street.

Access to the Port Administration Building’s driveways will remain open throughout. The project will stretch from Pico Avenue southeasterly to about 300 feet before Harbor Scenic Drive.

Toward the end of 2010, traces of crude oil were found in the Port’s 20-inch main waterline. Precautions have been taken since to ensure water quality. This $1.5-million replacement project is the last major step to address this issue with the Port’s water supply.
