Carbon Canyon Road Speed Limit Changes

Sorry for the long delay between posts and this is not exactly the latest news, but, about two weeks ago, the speed limit in the Orange County/Brea portion of Carbon Canyon Road (State Route 142) was changed.  Here is what is noticed with the new progressive limits:

Westbound

County line to near the old Manely Friends stables:                            40mph

From Manely Friends to former La Vida Mineral Springs resort:       45mph

From La Vida to Valencia Avenue:                                                       50mph


Eastbound

Valencia Avenue to near Manely Friends:                                            50mph

Manely Friends to west of Sleepy Hollow:                                           45mph

From west of Sleepy Hollow to county line:                                         40mph

It should be added that, so far as this blogger knows, there have been no changes on the San Bernardino County/Chino Hills side (Eastbound: 35 through Sleepy Hollow, 45 from there to just past Fairway Drive/Ginseng Lane, 40 through the S-curves [though no one can actually drive that speed through virtually all that section] and then 45 from past Old Carbon Canyon Road to Chino Hills Parkway; westbound: 50 from Chino Hills Parkway to approaching Summit Ranch, 45 to just before Old Carbon Canyon Road, 40 through the S-curves to Fairway Drive/Ginseng Lane, 45 to just before Sleepy Hollow, 35 to the county line)

There are two CalTrans districts operating within the Canyon and it was District 12 that made the decision to revise limits on the Orange County side, while District 8 handles the San Bernardino County portion.  Why the change was made, especially to increase from 45 to 50 eastbound from Valencia, is not known.  Vehicles, when the road is clear, generally fly downgrade from Valencia and it is surprising the limit is not lower when approaching and passing through Olinda Village.  The higher limit through sections with some strong curves through the canyon is also somewhat eye-opening.  We'll see if more accidents result from the change, though some people drive way beyond these limits anyway.
