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. It is discontinuous near Sacramento, being an unsigned route that runs concurrently with Interstate 5, Route 99, and U.S. Route 50.[3]

Route description[edit]

SR 16 is part of the California Freeway and Expressway System[4] and is eligible for the State Scenic Highway System.[5] However, it is not designated as a scenic highway by Caltrans.[6] It is known as the Stanley L. Van Vleck Memorial Highway from Dillard Road in Sacramento County to the Amador County line.[7]

Western section[edit]

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 Central Valley, SR 16 interchanges with Interstate 505 before heading east toward Woodland. In west Woodland it merges with County route 22 and then turns north, concurrently with County Route E7 and Interstate 5 Business, until it merges with Interstate 5.

Although SR 16 continues south on Interstate 5 south to U.S. Route 50, this concurrency is not signed or designated on most maps.[3][8]

Eastern section[edit]

The eastern segment of SR 16 begins at U.S. Route 50 east of Sacramento. SR 16 heads east through Perkins as Jackson Road. After it passes near Bridge House 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.[3][8]

History[edit]

SR 16 heading east through Yolo County, California.

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.[9] Each was connected to Sacramento by existing or planned paved county highways.[10] 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.[11][12] 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[13] in September 1925.[14][15] 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.[16][17] 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.[18] 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.[19][20] In the 1964 renumbering, Route 16 became the new legislative designation,[21] and Sign Route 24 through Sacramento was replaced with State Route 99 and State Route 160. As neither of these used what had been Sign Route 24 along 3rd and 5th Streets and Broadway, part of Route 16's new definition ("Route 5 near Woodland to Sacramento") was used for several years on this alignment until it became part of State Route 99 later that decade. This left the western segment of SR 16 ending at Interstate 5 near the east end of the I Street Bridge[22] until 1984, when the Woodland-Sacramento portion, which had become redundant with the parallel Interstate 5 complete, was deleted from the legislative definition.[23] It was at about this time that SR 16 was rerouted from the intersection with County Route E7 to continue north on a bypass of Woodland instead of east to Interstate 5.[1]

Major intersections[edit]

Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, and do not necessarily reflect current mileage. R reflects a realignment in the route since then.[24] The numbers reset at county lines; the start and end postmiles in each county are given in the county column.
