Tulalip Tribes Selects Parametrix for I-5 Interchanges Improvements Project

11.04.19

4th Street Interchange

Seattle, WA – Parametrix has been selected by the Tulalip Tribes to develop alternatives that increase capacity, safety, operations, and mobility at the 4^th Street NE and 88^th Street NE I-5 interchanges.

88th Street Interchange 

The Tulalip Tribes is a federally-recognized Indian tribe located on the Tulalip Reservation, bordered on west by the Puget Sound and on the east by the City of Marysville and Interstate 5. Access to the reservation is dependent upon three interchanges on I-5. One of those interchanges, 116^th Street NE, is currently in the final phase of construction.

Traffic on the 4th Street and the 88th Street I-5 ramps hinder commerce, commuters, and visitors on the reservation. Congestion at the interchanges cause delays on I-5 when the off ramps back up on to the mainline.

Quil Ceda Village serves as the economic engine for tribal jobs and businesses and is accessed via these interchanges. The heart of the reservation for residences, tribal government, and other enterprises is accessed at the 4th Street NE interchange. These improvements are critical to the Tribes, surrounding communities, and the I-5 corridor.

The Tulalip Reservation includes 22,000 acres of land abundant with natural resource including marine waters, tidelands, fresh water creeks and lakes, wetlands, forests, and developable land. The Reservation is home to the Snohomish, Snoqualmie, Skagit, Suiattle, Samish and Stillaguamish Tribes. Its boundaries were established by the 1855 Treaty and by Executive Order of President U.S. Grant dated December 23, 1873. The Tribes mission is to “create a healthy and culturally vibrant community.”
