Recent Progress
The completion of the environmental impact statement process was signified by the receipt of the record of decision in August. With that milestone, WSDOT has officially taken the lead project role, beginning preliminary design. A preliminary agreement was reached with Pierce County to transfer more than $5 million in grant funds to WSDOT. Pierce County is pursuing the acquisition of an environmental enhancement site near Roy.

Design Construction Impacts
This project will construct a new highway connecting I-5 and SR 7. To accomodate the I-5 connection, the project will modify the Thorne Lane interchange. A new southbound connector roadway will link Gravelly Lake Drive to Thorne Lane to minimize construction impacts on interstate traffic. The Thorne Lane interchange reconstruction will be accomplished south of the existing interchange, allowing motorists to use the existing facility during construction of the new Thorne Lane bridge over the Interstate.

Environmental Impacts / Compliance
The Record of Decision was delayed from June to August 2004 as Pierce County engineers addressed impacts the project will have on a bald eagle that recently created a nest on the proposed alignment.

Impacts to Traffic
Project designs will incorporate sound traffic managment practices in order to minimize impacts to motorists.
