WSDOT completed this project one full construction season ahead of schedule, delivering the new I-5, LaBree Road interchange (Exit 74) to the public on June 2, 2009. 

Interstate 5 is the backbone of the Washington State transportation system. It is the first stage of several with the goal of improving freight mobility, economic development and safety through the I-5 corridor between the Toutle River Safety Rest Area in Cowlitz County to Grand Mound Road in Thurston County.

As a result of this project, I-5 from the Rush Road interchange to the 13th Street interchange in Lewis County is a concrete barrier-divided interstate with three general-purpose lanes in each direction (six lanes total). In addition, access to the Chehalis Industrial Park is improved as a result of a new interchange at LaBree Road.

Why did WSDOT build an interchange at LaBree Road?
The new I-5, LaBree Road interchange (Exit 74) will help improve the economic viability of the Port of Chehalis, which results in creating more family wage jobs in the local community. 

It is estimated that following the construction of the interchange at I-5 and LaBree Road, round-trip truck travel time to and from the Port of Chehalis will be reduced by an average of seven minutes by the year 2030.

How You Benefit
Cross GlyphImproves Safety
The new LaBree Road interchange helps reduce collisions on I-5, the ramps and local roadways, and helps eliminate pedestrian and passenger vehicle conflicts with large trucks by moving truck traffic from the local roadways back onto the interstate.
Car GlyphRelieves Congestion
Widening this segment of I-5 improves traffic flow through Lewis County.

Additionally, this project improves roadway capacity by widening approximately four miles of I-5 from the Rush Road interchange to 13th Street interchange in Lewis County.
Dollar Sign Glyph Economic Incentive
The new LaBree Road interchange will help improve the economic viability of the Port of Chehalis, which results in creating more family wage jobs in the local community.

Partnerships & Cooperation
Several public involvement opportunities occurred beginning early 2004, when the preliminary project design and environmental review work began.

WSDOT first introduced the project to the public at an Open House and Scoping Meeting in April 2004 at W.F. West High School in Chehalis.

A combined Open House and Access Hearing for affected property owners occurred in April 2005 at W.F. West High School. The open house provided interested parties an opportunity to view project exhibits, and to meet project team members prior to the start of the access hearing.

In September 2005, WSDOT hosted an open house at its Chehalis Area Engineering Office to allow the public to review and comment on the recently completed Environmental Assessment for the project. Project staff also were also available to answer questions about the project and the Environmental Assessment. Read the press release, or the August 2005 Newsletter (.pdf 3.3 MB) for more information.

An opportunity to learn more about the project construction took place at an open house in June 2007 in Chehalis.

WSDOT makes every effort to assess and minimize environmental impact from our projects. In August 2005, WSDOT completed an Environmental Assessment for this project. This assessment determined what the potential impacts of possible alignments would be on the environment (natural, ecological, social and economic); evaluated options for lessening these impacts; and determined necessary regulatory approvals. The Executive Summary (.pdf 119 kb) from the Environmental Assessment is available on this Web page.

During project design, WSDOT worked to reduce the impact to wetlands, creeks and rivers in the project area. Any documented fish-passage barriers, such as culverts that prevent migration of spawning fish, were removed.

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 process was not applicable because the project did not impact tribal lands.
