Capitol Boulevard is the primary north-south arterial through the City of Tumwater, serving a wide array of businesses, neighborhoods, and employment centers. The intersection improvements are part of a master plan to improve economic conditions, mobility, pedestrian and bicycle facilities, and aesthetic appeal throughout the corridor.
SCJ’s efforts, including obtaining timely WSDOT approvals, paved the way for $7 million in grants to rebuild the intersection and modify the northbound ramps in the I-5/Trosper Road interchange. Significant improvements include three new roundabouts, ramp realignments, raised center median to better control driveway access, treatment for stormwater runoff, enhanced pedestrian/bicycle facilities, and waterline upgrades.
