Wilfred Avenue Interchange Project

This Project Has Been Completed


Welcome to the Wilfred Avenue Interchange Construction page. The first link below is a full version of the most recent IS-EA document. While the 28MB document may quickly be downloaded by users with DSL and Cable access, it is too large for those with only a 56k connection. To assist users with 56k or other dialup access, we offer a smaller text-only version of the document. Within the document are references to the specific images, which users can also download below, one at a time, on this web page.

The project will construct two new lanes, one northbound, one southbound, with both lanes functioning as HOV lanes; construct new, wider on and off ramps; build a new overpass; and build a new, straight underpass linking Wilfred Avenue to Golf Course Road. When completed, the new HOV lanes will link to existing HOV lanes to the north, and to-be-constructed HOV lanes in the south.

In addition to relieving congestion, the project will resolve the long-standing problem of traveling from one side of Rohnert Park to the other. Currently, the east and west sides are linked in this area by Commerce Boulevard, a rather long, circuitous route under the highway. When completed, eastern and western Rohnert Park will be joined by a short, straight, wide road that runs beneath the highway.

The project stretches along U.S. 101 from Rohnert Park Expressway in the south to Redwood Road in the north, a distance of 1.6 miles. The $40 million dollar project is expected to reach completion in late 2012.

Project Scope
Located in Rohnert Park, Sonoma County, this project proposes to modify the Wilfred Avenue/Golf Course Drive Interchange by constructing a new bridge undercrossing structure linking Wilfred Avenue to Golf Course Drive, and modifying the existing ramps. This project also proposes to realign and widen Route 101 from 4 to 6 lanes for High Occupancy Vehicle (HOV) lanes from the Rohnert Park Expressway Overcrossing to the Santa Rosa Avenue Overcrossing, a length of approximately 2 kilometers or 1.6 miles . . .
