Source-derived summary

State Route 86 (SR 86) is a north–south state highway in the U.S. State of California that connects the Imperial and Coachella valleys in the southeastern desert region of the state. It runs from State Route 111 near the Mexican border crossing at Calexico north through the Imperial Valley via El Centro and Brawley, and around the west side of the Salton Sea into the Coachella Valley. It then goes through Coachella before terminating at Interstate 10 in Indio. Though some maps and signs may mark SR 86 as continuous through the City of Imperial, control of the route within the city was relinquished to that local jurisdiction and is thus no longer officially part of the state highway system. There are further plans for the state to relinquish control of the entire southern segment of SR 86 between its terminus at SR 111 and SR 78 near Brawley.

Route description

Route 86 is defined in section 386, subdivision (a), of the California Streets and Highways Code:

Route 86 is from:

(1) Route 111 to Route 8 near El Centro.

(2) Route 8 near El Centro to the southern limit of the City of Imperial.

(3) The northern limit of the City of Imperial to Route 10 in the City of Indio via the vicinity of City of Brawley.

Subdivision (b) permits the state to relinquish control of the southern portion of the highway between its terminus at Route 111 and Route 78/Fredricks Road north of Brawley to local jurisdictions. Since the City of Imperial took control of its segment of the highway by 2018, subdivision (e) further mandates that the city must still "maintain within its jurisdiction signs directing motorists to the continuation of Route 86".

Editorial analysis

Why this record matters

“California State Route 86” is worth following because a concise public description often conceals a longer documentary argument. Here, California, State and Route provides the most credible route into that argument.

Critical limits

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.
