The potential of a split diamond interchange at Washougal River Road and 27th Street will need federal and/or state financial support to move forward.
Washougal Interim Public Works Director Jim Dunn said funding for the potential $98 million project would be needed for project planning, design, permitting and construction. The process is expected to take up to 10 years.
The option, recommended by Dunn, would include frontage roads with grade separation of railroad tracks at 27th.
Another option recently presented to the Washougal City Council and Port of Camas-Washougal Commission included full diamond interchanges at Washougal River Road and 32nd Street, with grade separation of railroad tracks at 32nd. The estimated cost of that option is $105 million to $120 million.
Option “C” includes a half diamond at Washougal River Road and 32nd, with full frontage roads and grade separation of railroad tracks at 27th. Its cost is estimated at $108 million to $134 million.
