Pacific Highway South HOV Lanes, Phase V (S 359th Street to S 340th Street)



Weekly Project Update (January 26, 2018)

State Route 99 (Pacific Highway South) is a major north/south urban arterial that serves both local and regional traffic within the City of Federal Way. It serves as a major route to the City of Federal Way, and it connects the Federal Way Regional Growth Center to the Tacoma Regional Growth Center and Port of Tacoma to the south and SeaTac Regional Growth Center to the north.

Currently, Pacific Highway South experiences significant traffic congestion and unsafe pedestrian facilities. This project has been in the City's Comprehensive Plan since 1990, with the objectives of improving traffic and pedestrian safety and circulation; supporting the use of transit and carpools; providing landscaping; and enhancing the overall aesthetics of the urban route. This project is funded by the City and two federal grants.

The improvements will include widening of the existing five-lane roadway to a six-lane section, including two general-purpose lanes and one HOV lane in each direction, and a landscaped median with provisions for left turn lanes and U-turns at intersections.

Pedestrian improvements will consist of curb, gutter, and sidewalks incorporated along both sides of the roadway. The sidewalk will be separated from the roadway by a planter strip in most locations, providing room for street lighting, street trees, and other landscaping.

Aesthetic improvements will include a planter strip between the curb and sidewalk. The median islands will be landscaped where they are wide enough.

With the exception of the high electrical transmission lines, all overhead utility distribution lines will be undergrounded. The transmission lines will be relocated to new poles, which will be spaced farther apart than the existing poles.

The project design started June 2013. Right-of-way acquisition is complete. Project construction is under way and is expected to be complete in 2018.
