More traffic control coming to Alpine Road/I-280

 

To encourage drivers to pay attention to stop signs at the intersection of Alpine Road and Interstate 280, the state is installing additional traffic control mechanisms. Some are already there.

On Sunday, Feb. 22, workers from the California Department of Transportation etched the pavement on the exit ramp of northbound I-280 to create rumble strips ahead of the stop and yield signs at Alpine Road, according to Caltrans spokeswoman Gidget Navarro.

The corrugated pattern in the pavement creates vibrations inside vehicles so as to warn drivers of the need to stop.

Rumble strips are planned for Alpine Road itself ahead of the stop signs that control eastbound and westbound traffic, but it might be another 10 days, Ms. Navarro said. The truck that does the etching broke down.

Caltrans will also be replacing five stop signs at the intersection with new and much larger signs, Ms. Navarro said.

Safety is a concern. In 2010, at a spot where bicycle and vehicle traffic converged without pavement markings to direct traffic, a cyclist collided with a truck and died. In a long awaited response, San Mateo County Public Works installed green bike lanes in 2013.

Recently, a group of Portola Valley residents complained to Caltrans (which owns the right-of-way there) about drivers blowing through the intersection's stop signs. Caltrans responded within weeks, residents said.
