Funding Secured for DuPont-Steilacoom Road Expansion

The 2019 Washington State Transportation Budget allocated $3.9 million to fully fund the construction of expanding of DuPont-Steilacoom Road.

The project will expand the current two-lane road to four lanes from Exit 119 to Wharf Rd/JBLM Integrity Gate. This 1.3-mile stretch is part of WSDOT’S Connecting Washington project, which will construct a new Exit 119 and connect to DuPont-Steilacoom Road. The project will also include a sidewalk for pedestrian and bicycle travel from Bell Hill to Wilmington Road.

Approximately $3 billion in commercial activity travels on this road annually.  In addition to the freight use of this road, it is also a popular commuter path. On average 23,000 vehicles use this road daily. For JBLM it connects two of their busiest gates, DuPont Gate to Integrity Gate and is the only connection for oversized military equipment from Lewis North to Lewis Main.

Widening the road preserves the ability to recruit and retain major business, provides better access for soldiers, helps secure the future of JBLM in Washington, and lessens congestion for traffic. 

DuPont-Steilacoom Road is on federal land and is maintained and operated by Pierce County. The easement will be transferred to DuPont to operate the stretch of road.

The City of DuPont has been working diligently for three years to get this project funded. Thank you to Senator O’Ban, Representative Kilduff, and Representative Leavitt for their support.

This project is a regional effort by the 28th Legislative District Delegation, Pierce County, Port of Tacoma, Town of Steilacoom, City of DuPont, and JBLM. $650K has been committed to the design/environmental study. Of that the City of DuPont is paying $350K, Pierce County is paying $100K, Port of Tacoma funded $50K, Sound Transit has allocated $150K and JBLM has provided land for the expansion.

Mayor Courts was quoted as saying “This is a major win for the City of DuPont and Pierce County. Today, approximately $3 Bil worth of commerce leaves DuPont’s commercial/industrial section via DuPont-Steilacoom Road annually. As new developments come on line this amount will only grow. Additionally, 23,000 passenger vehicles pass the intersection of Center Drive and DuPont-Steilacoom Road daily. DuPont-Steilacoom Road has also become a major I-5 bypass when I-5 becomes blocked North or South of the City. This expansion, tied to the new exit 119 and I-5 expansion will dramatically ease congestion and facilitate commerce. The area in front of the Historic Village will see a significant reduction in traffic as the exit 119 entrance/exit shifts to North of Barksdale Station. I am grateful for the cooperation from Port of Tacoma, Pierce County, JBLM Garrison, Department of Commerce, WSDOT, Town of Steilacoom and our Legislative Delegation. This was a team effort that took over three years to bring to reality. I look forward to completing the design and environmental work and moving onto the construction phase. As someone who lives off of DuPont-Steilacoom Road, I understand the inconvenience we will experience during the construction phase, but look forward to the improved traffic flow upon completion.”
