Traffic Information

Water traffic update: Although the sun is out, boaters are still requested to avoid travel on the Stanislaus River near the McHenry Avenue Bridge.

The Improve McHenry Avenue construction team is advising boats to stay clear around the McHenry Avenue Bridge construction site on the Stanislaus River.  The recent heavy rainfall caused a rise in water flow requiring construction crews to remove the decking of the temporary bridge trestle. Water levels are too high for boats or rafts to pass under the remaining steel beams. If water levels continue to rise, the remaining beams could become submerged creating potential underwater obstructions. The high-water flow is also cause for excess river debris to travel through the construction area, which may aggravate conditions. 

With the consistent rainy weather and upcoming snowmelt, the water flow will remain high. Boaters are advised to avoid the McHenry Avenue construction work area.

Project Information

The McHenry Avenue Corridor Improvements project will enhance safety, inter-regional traffic circulation, and air quality. The improvements will include:

  • 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.
