Project Description
Improves freight mobility, economic development and safety by adding one lane in each direction from Rush Road to 13th Street and constructing an interchange at LaBree Road. There are currently four lanes (two in each direction). There will be six lanes when this project is completed.

Recent Progress
In February 2004, the LaBree interchange was conditionally approved by the Federal Highway Administration. The conditions for approval were to improve the operational efficiency and the safety of the Interstate corridor in the Centralia/Chehalis area.
The consultant, CH2M Hill, has started the preliminary engineering to define the foot print of the project so the environmental documentation can proceed.
Two of three stormwater workshops were held in February and March. The workshops are a crucial element in helping define solutions to methods for treatment of the water runoff.

Design Construction Impacts
Stormwater treatment is a major factor in determining the need and amount of additional right of way, the total cost and the project scope. This design element has been identified as one of the most important aspects for successful project delivery.

Environmental Impacts / Compliance
Some wetlands will be unavoidably impacted. The North Fork Newaukum wetland bank credits will be used to mitigate these impacts. A hazardous material site has been identified and is located in the southwest quadrant of the LaBree Road interchange. Project impacts are unknown at this time.

Impacts to Traffic
Construction will be staged and an aggressive public awareness campaign will be used to minimize traffic impacts. I-5 may be restricted to one lane, each direction at night while staging is completed. Two lanes will be open in each direction during the daytime and at night as staging allows.
