Post Date:12/05/2018 4:55 PM

Maple Valley, Wash. – December 5, 2018 – On November 26, 2018 the City of Maple Valley was awarded a Washington State Transportation Improvement Board (TIB) Grant in the amount of $4,000,000 for the construction of improvements on Maple Valley-Black Diamond Road (SR-169).

The full cost of the project including design, right of way acquisition, construction materials, and construction management fees is estimated at approximately $7,257,000. The remaining project costs will be funded through a variety of City revenues that include traffic impact fees, transportation benefit district funds, stormwater funds, and real estate excise taxes.

The project boundaries are on SR-169 from Witte Road SE to SE 240th Street. The project scope includes intersection improvements, adding a second northbound travel lane, bike lane, sidewalk, retaining walls, and drainage improvements. This project will add capacity to the SR-169 transportation corridor, improve traffic flow, and provide multi-modal (bicycle and pedestrian) enhancements.

This project is included in the City’s 2019 – 2024 Six-Year Transportation Improvement Plan that was adopted by the City Council on July 9, 2018 (Resolution No. R-18-1257).  A Request for Proposal (RFP) for project construction is scheduled to be issued in January 2019 with construction anticipated to begin in Spring 2019. The anticipated project completion date is scheduled for October 2019.

Since this road construction project is expected to impact traffic and cause delays drivers are encouraged to plan their trips accordingly. Please visit the Public Works section of the City’s website at www.maplevalleywa.go for more project information and updates.
