California Department of Transportation (CalTrans): Stop the Use of Chip Seal on Highways Frequented by Bicyclists, and Repair Projects Already Installed on such Highways

    1. Petition by

      Pasadena Athletic Association

Angeles Crest Highway is the gateway to the Angeles National Forest for many Southern Californians. Hikers, road and mountain cyclists, motorcyclists, and more all use the stretch of highway between La Canada Flintridge and Wrightwood to access forest trails, patronize businesses such as Newcomb's Ranch, and simply enjoy the stunning views and scenery.

To the east, Highway 39 and Mt. Baldy Road are similarly frequented by cyclists and other recreational users. These roadways and others like them across the State of California provide wonderful recreational opportunities for residents and visitors alike.

The Facts:

CalTrans resurfaced Highway 2 from La Canada Flintridge to Wrightwood with a layer of chip seal in the summer of 2013.

This stretch of roadway was in fairly good repair, due in part to road work, repair and repaving conducted in 2010-11  following the Station Fire.  In contrast, other nearby sections of highway, such as Angeles Forest Highway to Palmdale, were in far greater need of improvements.

The rock aggregate used in the resurfacing is very rough, and makes riding a bicycle highly uncomfortable and more dangerous, especially when descending. This reality is plain in the photo above, which juxtaposes the chip seal and “old” roadway surface.

In September 2013, a section of Mt. Baldy Road also received a layer of chip seal, despite the safety concerns expressed to staff by local road users.

According to the Caltrans District 7 Public Information Officer, “Caltrans is committed to providing the safest, most comfortable experience for all users of the state highway system.” Yet this road treatment continues to be employed by the agency, despite its awareness of the cycling community’s concerns regarding the safety and comfort of chip seal.

      Thanks to the over 1600 of you who expressed concern about the chip-seal roadway surface unnecessarily applied to Angeles Crest Highway, CalTrans has volunteered to test a Sand-Seal mitigation treatment along a segment of the roadway.

      We are already working with UC Davis to address this issue. We are working on a similar solution as what was done in San Luis Obispo County. We informed several members of the cycling community during our Bicycle Advisory Committee meeti...

      The chip sealing (downgrading) of road surfaces that have smooth paving should never be done.

      The prison laborers that helped build this highway in 1936 put more care, pride and thought into it than Caltrans did in 2013. It's now noisy and unsafe for all wheeled vehicles.
