California State Route 160
State Route 160 (SR 160) is a state highway in the U.S. state of California consisting of two sections. The longer, southern section is a scenic highway through the alluvial plain of the Sacramento River, linking SR 4 in Antioch with Sacramento via the Antioch Bridge. The northern section, separated from the southern by Sacramento city streets, is the North Sacramento Freeway, running from the 16th Street Bridge over the American River to Interstate 80 Business towards Roseville.
This northern section was erroneously deleted from the definition in the Streets and Highways Code in 2003 when the relinquished portion through downtown Sacramento was removed; the segment was restored in a 2010 amendment to the code. Although it is no longer officially part of the state highway system, some maps may still mark SR 160 as continuous through the city.
State Route 160 begins in eastern Antioch at SR 4 as a four-lane freeway. After two interchanges, SR 160 becomes a two-lane expressway and rises onto the Antioch Bridge over the San Joaquin River. It cuts north across the center of Sherman Island as a two-lane surface road, reaching the Sacramento River on the opposite shore. From there to Sacramento, SR 160 remains near the river, first following the east levee over the 1949 Three Mile Slough Bridge, a lift bridge, across the Three Mile Slough and past Brannan Island State Recreation Area. SR 160 intersects with SR 12 near Rio Vista, right before SR 12 crosses the Sacramento River via the Rio Vista Bridge. After passing Isleton, SR 160 crosses the Sacramento River on the Isleton Bridge, a bascule bridge built in 1923, and runs along the west shore on Grand Island, where it meets the east end of SR 220. The Walnut Grove Bridge carries SR 160 and CR J11 east concurrently across the river to Walnut Grove, and, at the north end of the island, SR 160 crosses the 1924 Steamboat Slough Bridge onto Sutter Island and then the 1923 Paintersville Bridge across the Sacramento River to the mainland, both bascule bridges.
On the mainland, SR 160 once again runs atop the east levee, now 1–2 miles (1.6–3.2 km) west of I-5. The final bridge over the river is the Freeport Bridge, which carries CR E9 to the west levee, where it turns south to return to SR 160 at the west end of the Paintersville Bridge. About 1 mile (1.6 km) beyond the Freeport Bridge, SR 160 leaves the levee, enters the city of Sacramento, where the southern portion of SR 160 ends and state maintenance and control ends. It then passes under I-5 and enters into a more suburban landscape. Here the former SR 160 is known as Freeport Boulevard, a major surface road that passes the Sacramento Executive Airport and Sacramento City College. Freeport Boulevard turns to the northwest at about 4th Avenue. It was formerly a one-way pair with 21st Street with Freeport Boulevard heading one-way southbound and 21st heading one-way northbound. The city converted these streets back to two-way streets for traffic calming purposes in 2008. After a short distance on Broadway, former SR 160 turns north on the one-way pair of 15th (southbound) and 16th (northbound) Streets and enters downtown Sacramento after an interchange with US 50.
15th and 16th Streets lead traffic north past the east side of the State Capitol grounds, which lie between L and N Streets. At F Street, the path of southbound former SR 160 turned west for three blocks on F street before turning north again on 12th Street; both 12th and 16th Streets pass under the Union Pacific Railroad's Martinez Subdivision, where B Street would be, in four-lane subways, but 15th Street meets a dead-end after its intersection with C Street. 12th Street remains a one-way southbound roadway while the two-way SacRT light rail occupies its east side. 12th Street turns northeast at North B Street, and the two directions of former SR 160 come together at Richards Boulevard, just south of the 16th Street Bridge over the American River and the south end of the state-maintained North Sacramento Freeway. The light rail, which crosses the river between the two directions of SR 160, soon leaves at the Del Paso Boulevard interchange as the four-lane freeway turns east, ending at the Capital City Freeway (Interstate 80 Business) at Arden Way, near Arden Fair Mall.
The northern portion is also part of the California Freeway and Expressway System, and so is the piece south of SR 12 near Rio Vista, though only the southernmost piece of SR 12 in Antioch is built to freeway standards. The northern and southern pieces south of SR 12 are also 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. The entire southern portion from SR 4 to Sacramento is eligible to be included in the State Scenic Highway System and is officially designated as a scenic highway by the California Department of Transportation, meaning that it is a substantial section of highway passing through a "memorable landscape" with no "visual intrusions", where the potential designation has gained popular favor with the community.
In the late 1910s, Sacramento County improved the county road along the levee of the Sacramento River between Sacramento and Rio Vista, which crossed the river twice on free ferries near Paintersville and Isleton. A toll ferry across the San Joaquin River connected Sherman Island, south of Rio Vista, with Antioch, where drivers could head west through the Broadway Tunnel to reach the San Francisco Bay, but the road between Rio Vista and the ferry was poorly paved. In 1922, the Victory Highway Association selected this "Netherlands Route", though locally promoted as the "Netherlands of America", for the Victory Highway west of Sacramento, as it was both shorter than the Lincoln Highway route via Stockton and more scenic. In particular, the river district would "impress [the motorist] with the enormous productive resources of this state as well as supply him with an unmatched scenic drive", and the Broadway Tunnel approach to the bay would bring him "over the Victory Highway to the end of his journey in such a fashion that he will never forget the view spread before him as he first comes into sight of the San Francisco Bay region".
Two bascule bridges—the Paintersville Bridge and Isleton Bridge—replaced the free ferries in 1923, and are of a type patented by Joseph B. Strauss, who went on to design the Golden Gate Bridge. Local businessmen Aven Hanford and Oscar Klatt replaced the toll ferry with the tolled Antioch Bridge in mid-1926, almost a year before they opened the larger Carquinez Bridge to the west. The counties of Contra Costa and Sacramento organized a joint highway district in November 1925 to fund an improvement of the northern approach from Rio Vista; the concrete highway was completed in July 1927, creating a fully paved continuous route between Sacramento and the Bay Area.
