Grant applications
The City of Longview and its partners are seeking an additional $13 million through the Infrastructure for Rebuilding America (INFRA) discretionary grant program. The City submitted this proposal in mid-March. WSDOT is continuing work with local partners to modify the design of the project and reduce the cost while maintaining key benefits.

Draft Environmental Impact Statement (DEIS)
The Draft Environmental Impact Statement (DEIS) was published on March 2, 2018, and its 45-day comment period concluded on April 16, 2018. The DEIS evaluated two design alternatives against a no-build alternative.
The DEIS outlines direct impacts and benefits of the alternatives to the natural and built environment. It also takes into account construction, indirect and cumulative effects of the alternatives and identifies ways the impacts can and should be mitigated as the project progresses.
