Design Construction Impacts
The project Geotechnical report identified that there will be both short and long term settlements on the new bridges and roadways. Both over-excavation and replacement of unsuitable material and pre-loading construction methods will be utilized to address the settlements.

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.
During the earthwork for the realignment of the local roads a site requiring a cultural investigation was located. Upon completion of the investigation it was determined that this discovery was not eligible for National Register listing.

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. The LaBree Road overcrossing will be closed during construction due to the construction of the new interchange at this location.
