Construction on a project to improve the 62nd Avenue Northwest and 144th Street Northwest intersection began April 9. The project is expected to be complete in late December or early 2020.
About the Project
The improvements are intended to improve safety and increase the efficiency of the intersection. Improvements will include the following:
Installing a traffic signal system.
Providing street lighting on 144th Street Northwest.
Adding a westbound left-turn lane on 144th Street Northwest at the intersection.
Adding a two-way left-turn lane on 144th Street Northwest from 62nd Avenue Northwest to the school parking lot entrance.
Providing a northbound left-turn lane and a right-turn lane on 62nd Avenue Northwest.
Constructing retaining walls.
Adding stormwater treatment facilities and detention vault.
The majority of the work will be completed during the summer months to minimize impacts to Peninsula School District students, staff and parents.
From April 9-16, crews cleared bushes and trees, removed guardrails and excavated shoulders.
Utility companies will be onsite relocating utility lines and poles starting April 26.
Construction work will start back up on July 1, with crews installing retaining walls and temporary drainage facilities, and constructing a temporary one-lane bypass road along the shoulder of the east side of 62nd Avenue Northwest.
While the bypass road is in place, crews will excavate and rebuild 62nd Avenue Northwest. A stormwater detention vault will be installed under the road before the road is rebuilt. The bypass is expected to be removed Aug. 15 and 16.
From late August to late September, crews will widen and resurface 144th Street Northwest, continue installing storm drainage facilities and retaining walls, install street lights, apply temporary striping, and install guardrails.
Work will be suspended from late September to mid-December while poles for the traffic signal system are ordered. The new traffic signal will then be installed.
Final striping is expected in late December or early 2020.
During construction, crews will work from 7 a.m. to 3:30 p.m. Monday to Friday. Crews may work until 5:30 p.m. for several weeks this summer when the vault is being installed.
There will be alternating one-way traffic on 144th Street Northwest during work hours throughout the project as needed.
There will be alternating one-way traffic along 62nd Avenue Northwest 24-hours a day, seven days a week while the bypass road is in place from late June to mid-August.
Active Construction Inc. is the contractor. The construction cost is approximately $2.4 million and is funded with County Road Funds.
