State Route 16 (SR 16) is a state highway in the northern region of the U.S. state of California that runs from Route 20 in Colusa County to Route 49 just outside Plymouth in Amador County, primarily crossing the Sacramento Valley. Much of the route through the Sacramento area is unsigned as it runs on a concurrency with the I-5 and US 50 freeways.
