DANVILLE, Calif. – Today at Mount Diablo State Park, California State Parks held an event to commemorate recent road safety enhancements. California Senator Steve Glazer (D-Orinda), Assemblymember Catharine Baker (R-San Ramon), Diablo Cyclists and a number of partners were in attendance.  

Mount Diablo State Park, located in Contra Costa County, offers a picturesque panorama of the surrounding low, rolling hills and broad, flat valleys. When conditions are best, you can see almost 200 miles of remarkable views, including the Golden Gate Bridge. The state park is visited by countless motorists and bicyclists annually on the parks’ three narrow and winding roads.

Some of these narrow roads also contain blind curves where solo-cycling accidents, as well as accidents between cyclists and motorists have occurred. In an effort to decrease these types of accidents, parks officials, with the help of community leaders, identified resources and explored alternatives to implement additional safety measures throughout the state park.

Recent road safety enhancements include:  

  • Solid double yellow lines and designated passing areas
  • Bike “sharrows” or share-lane markings
  • “Do Not Pass Bikes on Blind Curves” signs,
  • “Avoid Crash, Slow Down” signs
  • Additional Stop signs for safety
  • Revised warning Curve/Speed Advisory signs
  • Improved Safety Communication to Mount Diablo State Parks’ Visitors

California State Parks extends its gratitude to the partners and community members who helped us make Mount Diablo State Park a safer place for all. Additionally, thank you in advance to all visitors who adhere to the improved safety enhancements and share the park with one another.
