I-5, Mellen Street to Blakeslee Junction

Overview
This project widened four miles of I-5 from two to three lanes in each direction between the Blakeslee railroad junction in Lewis County (milepost 83.5) and just south of the Grand Mound interchange (Exit 88) in Thurston County. This section of I-5 is now a barrier-divided interstate with three general-purpose lanes in each direction.

Why did WSDOT build this project?
I-5 is the most significant freight freeway on the West Coast. The interstate links markets in Canada, the United States and Mexico, and is critical to the regional, state and national economy.

WSDOT is investing $390 million from the 2003 and 2005 gas-tax packages in four projects – including this project – to improve traffic flow and safety along 18 miles of I-5 in Lewis and Thurston counties. By widening and improving the interstate corridor, this project helps reduce congestion, improve traffic flow and reduce the chance for collisions caused by traffic backups and merging conditions.

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. This project did not impact any tribal resources since the work was entirely above ground on existing WSDOT right of way. For more information visit our WSDOT Tribal Liaison website.

WSDOT makes every effort to assess and minimize environmental impacts from our projects. A detailed analysis of the project’s environmental impacts was completed as part of the environmental documentation and environmental permitting processes.
