WSDOT built a bicycle/pedestrian bridge over I-5 and a connecting trail for Snohomish County to improve safety and traffic flow at the 128th Street interchange.
We built this project in two stages and opened the bridge for use once we finished the connecting trail. Contractor Mowat Construction began building the bridge in fall 2005 and finished in summer 2006. We began building the connecting trail in fall 2007 and opened both the bridge and trail in April 2008.
We improved pedestrian, bicyclist and driver safety on this section of I-5 by separating trail users from traffic on the interchange at 128th St.
The bridge will relieve some congestion for drivers exiting and entering I-5 at 128th Street.
| Protects Environment
As we built the overpass we incorporated state and county environmental guidelines. Some of these guidelines included erosion control methods to protect wetlands during construction and beautification of areas impacted by the work.
Partnerships & Cooperation
At WSDOT we seek to address the concerns of the tribal nations using the process outlined in Section 106 of The National Historic Preservation Act and the WSDOT Tribal Consultation Policy adopted in 2003 by the Transportation Commission as part of the WSDOT Centennial Accord Plan.
Section 106 consultation was initiated with relevant tribes and other interested parties as the project developed.
To learn more about the tribal consultation process please visit WSDOT's Tribal Liaison page, where you'll find links to WSDOT Centennial Accord Plan and WSDOT's Tribal Consultation Policy (Adopted by the Transportation Commission on February 19, 2003).
