Soundwall Pays Off
January 2010
Patrick Murphy of San Rafael likes what he doesn’t hear. Crews are finishing the installation of thousands of sound-absorbing panels as part of a $3 million retrofit of the existing Highway 101 soundwall to give area neighbors relief from freeway noise.
It’s already making a difference.
“It’s a significant change,” said Murphy, who lives on Lincoln Hill in San Rafael and has lobbied Caltrans for more than a dozen years to improve the soundwalls. “The white noise that you hear is gone. What’s missing is the ‘shhhhh.’”
Application of the 11,400 sound-absorbing panels along the mile stretch of the existing east soundwall has been going on for the past six months.
