Past the southern terminus are Collinsville and Birds Landing around the Suisun Bay marshes.
The section running from Dixon to Woodland is a controlled-access freeway; the remainder is a standard road of two to four lanes.
After leaving Davis, SR 113 continues north through rural areas for a short while, entering Woodland approximately 7 miles (11 km) later.
It then heads northeast through the small community of Robbins, then turns east to end at State Route 99 towards Yuba City.
Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage.
