Design Construction Impacts
This project will construct a new highway connecting I-5 and SR 7. To accommodate 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 interstate traffic congestion. 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
During the EIS phase, the selected alternative was chosen because it avoids many sensitive areas. In locations where impacts are not avoidable, designs will minimize impacts to the environment by use of retaining walls and bridges.

Impacts to Traffic
Project designs will incorporate sound traffic management practices to minimize impacts to motorists.
