Driving Highway 101 through Rohnert Park will be more complicated for the next two years, as the road is widened and reconfigured.
Located in Rohnert Park, this project will 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 will also realign and widen Highway 101 from 4 to 6 lanes for High Occupancy Vehicle (HOV) or carpool lanes between the Rohnert Park Expressway overcrossing to the Santa Rosa Avenue 0vercrossing, a length of approximately 1.6 miles.
The first big change affecting traffic in this section of Highway 101 will be implemented early on the morning of September 29th, explains CalTrans spokesman Bob Haus, and will affect southbound traffic as it approaches Rohernt Park from Santa Rosa.
The scope of the work area, and the anticipated final result can be seen in the images below. The upper photograph shows the work area as it was before the project began, while the second image has been modified to show the configuration of the new lanes, ramps and bridges.
