From Cotati to Rohnert Park on Highway 116

West California 116 exit from US 101 northbound in Cotati

This exit sign marks the end of the nine-mile concurrence ("multiplex") between California 116 and US 101 in Sonoma County. In this photograph, taken in July 2009, you should be able to tell that the sign was still making use of button reflectors rather than the newer reflectorized signs, despite a minor amount of blurriness caused by less-than-optimal lighting conditions.
