Source-derived summary

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 the relinquished portion of SR 160 as continuous through the city.

Route description

Route 160 is defined in section 460, subsection (a), of the California Streets and Highways Code:

Route 160 is from:

(1) Route 4 near Antioch to the southern city limits of Sacramento.

(2) The American River in the City of Sacramento to Route 51.

While control of the segment of Route 160 in Sacramento between the southern city limits and the American River was relinquished by the state to the city, subdivision (b) further mandates that the city must still "maintain signs directing motorists to the continuation of Route 160".

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.

Editorial analysis

Why this record matters

The phrase “state highway in Contra Costa and Sacramento counties in California, United States” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 26, 2026.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
