Improving freight mobility and safety, as well as accessibility for trucks and automobiles, are among the goals of a project that could be completed in eight years.
Chris Hemmer, a supervising engineer with Parsons Brinckerhoff, provided information regarding the construction of a half-diamond interchange between Washougal River Road and 27th Street, during the Washougal City Council workshop last night.
The preliminary cost estimate for the project is $42.8 million. A 27th Street extension could cost an additional $15.2 million.
The next steps would involve working with the Washington State Department of Transportation and the Southwest Washington Regional Transportation Council and pursuing funding sources, followed by the preparation of environmental documentation and preliminary design during the next two years.
“There can be refinements, but this gives us something to talk about,” said City Administrator David Scott.
A final design could be completed by 2016, with construction to occur from 2017 to 2020.
A meeting with Mayor Sean Guard, Hemmer and a representative from the WSDOT is expected to occur in February, to further discuss the project.
