An electronic message sign for eastbound 120 Bypass traffic approaching Airport Way is the latest effort by Caltrans in a bid to reduce carnage on what has become the deadliest section of freeway in the Northern San Joaquin Valley. While the sign can be programmed remotely to flash whatever message Caltrans wants, its primary focus is to warn motorists of traffic slowdowns or stopped traffic ahead. There is already an electronic message sign in place closer to Highway 99.
