US cycle writer and historian Jim Langley is urging Californian cyclists to write to State Governor Jerry Brown to try and halt plans by Caltrans to install rumble strips on scenic, coastal Highway 1.
"Rumble strips endanger all cyclists," Langley told BikeBiz.com. "Highway 1 from San Fran to Santa Cruz is among the world's most-famous cycling routes, and has been since the 1960s."
Caltrans - the California Department of Transportation - plans to install centre and shoulder rumble strips on what - in parts - is a popular route with roadies. The to-be-rumbled stretch of road is also on the route of the pro race, the Tour of California.
"I just sent a letter to Governor Brown asking him to stop Caltrans from ruining our precious cycling route Hwy 1," said Langley.
Rumble strips are installed to slow down motorists but can be dangerous for cyclists.
Parts of Highway 1 is a US National Scenic Byway, a road recognized by the United States Department of Transportation for its scenic qualities.
