California 16

This view looks west along California 16 (Jackson Road) just after the Grant Line Road intersection in Sacramento County. California 16 travels northwest along Jackson Road until the intersection with Howe Avenue and interchange with U.S. 50 (El Dorado Freeway). Photo taken 03/15/15.

California 16 is currently divided into two segments. The western segment of California 16 begins at its junction with California 20 just east of Clear Lake, then heads southeast via Cache Creek Canyon to Rumsey, Esparto, and Woodland. The state route ends at Interstate 5 north of Woodland. The eastern segment of California 16 begins at its junction with U.S. 50 in Sacramento at Exit 9 and follows Howe Avenue and Jackson Road east to California 49 near Plymouth. Portions of the state highway nearest U.S. 50 within the city of Sacramento are being considered for transfer to local jurisdictions for operations and maintenance.


California 16 was commissioned as a state sign route in 1934. Originally, California 16 was one continuous state highway, with a signed alignment connecting the western and eastern segments. The route between Woodland and Sacramento followed Main Street (Business Loop I-5) east through downtown Woodland, Yolo County Road 22 east, Old River Road southeast (curving along the west bank of the Sacramento River), Harbor Boulevard south into the city of West Sacramento, Sacramento Avenue east, Sixth Street north, C Street east, Kiline Street east, I Street Bridge over the Sacramento River into the city of Sacramento, Third Street south/Fifth Street north (one-way couplet), Capitol Mall east (along Historic U.S. 40-99W), Seventh Street south/Eighth Street north (one-way couplet), N Street east (back when this was a two-way street; today is it one-way eastbound), 16th Street north/15th Street south (one-way couplet), Capitol Avenue east (along Historic U.S. 50), and Folsom Boulevard east until connecting with Jackson Road. The downtown Sacramento routing for California 16 described here was accurate as of the 1968 California State Automobile Association (CSAA) map of Sacramento; it may have had minor variations as streets converted between one-way and two-way status. A scan of this map is provided below

A portion of California 16 overlapped with former California 24 northwest of Sacramento. A later realignment may have moved California 24 (and definitely California 70) away from former California 16 and onto Garden Highway (which follows the east bank of the Sacramento River) and possibly Jibboom Street to link with the downtown Sacramento street grid. In 1964, California 24 was removed from Sacramento, and Cailfornia 70 was commissioned to follow the Jibboom Street and Garden Highway route leaving Sacramento to the north (see 1968 CSAA map of Sacramento below); its southern terminus was later truncated north to its split from California 99 northeast of the Sacramento International Airport. California 16 more or less remained on its route. Regardless, with the completion of the central Sacramento freeway network, the state highway designation along these streets became less necessary and redundant in keeping with California's general philosophy (post-1964) about limiting parallel state routes and removing urban streets from the state highway system when possible. In 1984, California 16 was removed from the local street network. After California 16 was removed, some maps show California 16 following the freeway network via Interstate 5, Business Loop I-80 (Capital City Freeway), and U.S. 50 between Woodland and Sacramento, but it is unclear if California 16 was ever signed along this route. Some remnant signage for California 16 remained in downtown Sacramento as late as the 1990s, but it apparently is gone as of 2015.

California 16 east
In Yolo County, eastbound California 16 approaches Interstate 505. The advance signage for Interstate 505 is not too good, so be prepared for the exit ramps to appear without much warning. Notice how little vegetation there is here, aside from the agricultural fields. Photo taken by Joel Windmiller (03/29/01).
Eastbound California 16 meets Willow Creek Road. Photo taken by Joel Windmiller (03/29/01).
Continuing east, California 16 approaches Yolo County E-7 in Woodland. Yolo County E-7 travels south from here via Road 98 and Pedrick Road, parallel to the California 113 freeway. Photo taken by Joel Windmiller (03/29/01).
California 16 west
Back in 2000, a roadside sign and end California 16 shield assembly were posted along northbound Howe Avenue at the U.S. 50 interchange just north of Jackson Road. By 2011, signs here were replaced with a new end shield and overhead guide signs (not shown). There is a gap in California 16 between this interchange and Woodland. Photo taken by Dominic Ielati, 03/00.
A set of three route markers for California 16 west, Yolo County E-7, and Business Loop I-5 (posted as To Interstate 5) used to be found in Woodland. It is doubtful these shields remain in place today. Photo taken by Trevor Carrier (Summer 2002).
Westbound California 16 approaches the on-ramp to Interstate 505 southbound. Photo taken by Joel Windmiller (03/29/01).
