Brea Canyon Cutoff Road

Diamond Bar, CaliforniaMay 02, 20070 Comments

LASD usually parks in the center meridian (near the fire road) after the curve. Vehicle is usually pointing downhill, but u-turns are easy enough. Speed limits vary between 35 @ E. Oak Crest Dr. to 40 on the uphill to 45 @ Pathfinder. Sheriff is also there during some evening rush hours. CHP also uses this as a shortcut to Starbucks between the 57 (dimond bld exit) & 60 (fairway exit).

Speed limit starts at 50 mph when heading south from Temple Avenue. As soon as you pass Highland Valley Road, it becomes 40 mph. Motorcycle cops hide out in the business center on your left side with a radar gun, knowing that the speed limit just dropped 10 mph and you may still be going 50.

Around 8AM in the mornings Monday – Friday, there is often a motor cycle patrol with some type of speed gun beneath a tree at Sycamore Canyon Park on Golden Springs Drive between Diamond Bar Blvd and Grand Ave. He is difficult to pick up the first time through. I think there’s a sign that says 45 mph.
