California State Route 16
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. There is a gap in the route in the Sacramento area, which can be transversed along the I-5 and US 50 freeways.
SR 16 is part of the California Freeway and Expressway System, and the eastern segment is part of the National Highway System, a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration. SR 16 is eligible to be included in the State Scenic Highway System, but it is not officially designated as a scenic highway by the California Department of Transportation. It is known as the Stanley L. Van Vleck Memorial Highway from Dillard Road in Sacramento County to the Amador County line, honoring a former prominent leader in the state's agricultural organizations.
State Route 16 begins in Colusa County near Wilbur Springs at the junction with State Route 20. SR 16 goes south alongside Bear Creek, which enters a narrow canyon and joins with Cache Creek near the Yolo County line. SR 16 continues in the canyon, running close to the river, passing Cache Creek Canyon Regional Park, and emerging from the canyon north of Rumsey. This section is so prone to rock slides that there are permanent gates at each end.
SR 16 continues to parallel Cache Creek, at a greater distance, going south-east through Capay Valley, with Blue Ridge to its west and the Capay Hills (including Bald Mountain) to its east. It goes through Rumsey, Guinda, Brooks, Cache Creek Casino Resort, Capay, Esparto (intersecting with County Route E4 to Dunnigan), and Madison.
East of Madison, and now in the Central Valley, SR 16 interchanges with Interstate 505 before heading east toward Woodland. In west Woodland, it merges with County Road 22 and then turns north, concurrently with County Route E7 and Interstate 5 Business, until it meets its interchange with Interstate 5, where its western segment ends.
The eastern segment begins at US 50, heading southbound on Howe Ave for a very short distance, then runs eastbound on Folsom Boulevard. SR 16 then peels off from Folsom Boulevard, less than a mile later as Jackson Road. After it passes near Sloughhouse and Rancho Murieta, where it crosses the Cosumnes River, SR 16 enters Amador County. SR 16 then ascends into the Sierra Nevada foothills, leaving the Central Valley. In Amador County, SR 16 passes near Forest Home before intersecting with State Route 124 and terminating at State Route 49.
The two ends of SR 16 were added to the state highway system by the third bond issue, passed by the state's voters in 1919: Route 50 from Lower Lake east to Rumsey and Route 54 from the Sacramento-Amador County line east to Drytown. Each was connected to Sacramento by existing or planned paved county highways. Although the exact alignment of Route 50 was not specified, the state Department of Engineering had already surveyed a 35-mile (56 km) route through Cache Creek Canyon pursuant to a 1915 law, which defined the Yolo and Lake Highway "following generally, the meanderings of Cache creek" but did not make it a state highway. By 1924, the California Highway Commission's engineers had realized that building Route 50 through the canyon was impractical, and adopted a substitute plan for two highways connecting Lower Lake and Rumsey with the planned Route 15 (Tahoe-Ukiah Highway, now State Route 20) to the north in September 1925. The western connection, to Lower Lake, became part of Route 49 (now State Route 53 there), which continued south from Lower Lake to Calistoga.
Each route was extended to Sacramento in 1933 over the aforementioned county highways, taking Route 50 southeast from Rumsey to Woodland near Cache Creek and then alongside the Sacramento River to the I Street Bridge, and Route 54 west from the county line to Route 11 just outside Sacramento. The entirety of both routes, from SR 20 near Wilbur Springs through Sacramento to State Route 49 just north of Drytown (and initially overlapping SR 49 to Jackson), was included in the initial state sign route system in 1934 as Sign Route 16. Through downtown Sacramento, SR 16 followed U.S. 40 (Legislative Route 6) and U.S. 50 (Legislative Route 11), mostly on Capitol Avenue, while Legislative Route 50 continued south on 5th Street (later a one-way pair of 3rd and 5th Streets) and turned east on Broadway, carrying Sign Route 24 most of the way to Freeport Boulevard.
