Design Construction Impacts
Stormwater treatment is a major factor in determining the amount of additional right of way needed, the total cost and the project scope. This design element has been identified as one of the most important aspects for successful project delivery.
The project Geotechnical report identified there will be both short and long term settlements on the new bridges and roadways. Both over-excavation and replacement with borrow material and pre-loading construction methods will be utilized to address the settlements. The LaBree road bridge over I-5 has been designed as a single span structure based on the current information.

Environmental Impacts / Compliance
The North Fork Newaukum wetland bank credits will be used to mitigate wetland impacts. A hazardous material site has been identified and is located in the southwest quadrant of the LaBree Road interchange.
|
Impacts to Traffic
No impacts during design. 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. LaBree road overcrossing will be closed during construction due to the construction of the new interchange at this location.
