San Gabriel Canyon Road (SR-39) Open!

Caltrans opened San Gabriel Canyon Road (SR-39) on Friday, April 22 at 3 p.m. to the public.
Gate open!
The highway was originally expected to open in early May.   The highway was closed to public access since January 6 at East Fork Road due to severe El Niño storms that cause several washouts and filled and damage debris basins along the roadside.   
Repaired slope, looking southward
Construction crews repaired the following:
  • Five washed out slopes were rebuilt and stabilized.
  • Roadside debris basins have been cleared.
  • Fiber mesh has been installed on the slopes to prevent future erosion from heavy rains.
  • 1,000 to 1,500 feet of asphalt concrete berms were reconstructed on the shoulder.
  • One hundred feet of the highway was repaved.
  • Nearly 2,000 feet of rip rap (rocks) was installed to prevent water and debris flows from damaging the slopes during heavy rains.
  • Over 10,000 yards of dirt was hauled out or used to rebuild slopes and berms. 
  • The highway was restriped.  
  • During heavy rains in January, mud and debris flows blocked drainage systems and washed out support slopes along the highway (post mile 28.0 to post mile 31.0) in the Cabin fire burn area. 
O’Donnell Construction Inc. of San Dimas, California was awarded this $2 million contract.  

Please Be Work Zone Alert.
