  • 1.1 miles of widening along McHenry Avenue from 1,487 feet south of River Road to 190 feet south of Jones Road.
  • Stanislaus River and SSJID Canal Bridges will be replaced with wider and safer bridges, satisfying current seismic design standards.
  • Installation of a two-way left turn center lane to facilitate turns into and out of driveways on McHenry Avenue.
  • Increased width of roadway shoulders to accommodate alternative travel modes, including bicyclists.
  • Installation of a traffic signal on McHenry Avenue and River Road that will accommodate existing and future traffic demands.
