The Grapevine / Tejon Pass

Sources: Caltrans District 7 for the Los Angeles interval · Caltrans District 6 for the Kern interval.

Covers I-5 from Parker Road through Tejon Pass to the I-5 / SR-99 separation — some nearby roads aren't monitored. See what's included.

This status covers the reviewed I-5 corridor in two county-strict intervals: Los Angeles from Parker Road at R59.01 to the Los Angeles / Kern county line at R88.605, and Kern from the county reset at R0.0 to the I-5 / SR-99 separation at Wheeler Ridge at R15.86. Lake Hughes Road is the official northbound closure gate, and Grapevine Road is the official southbound closure gate.

It doesn't include Operation Snowflake detours or any conditions on SR-58, SR-166, SR-46, SR-41, or US-101; those routes are context only and never part of this status answer. Verify those routes separately before traveling. Grapevine, Lebec, Frazier Park, and Castaic are orientation labels only, not members, pages, access hubs, or separately monitored destinations.

Conditions can change quickly in the mountains. This page never replaces chain requirements, closures, or official Caltrans guidance. Missing or stale required feed data, incomplete coverage, or a report that cannot be classified never becomes Open. This boundary supports no claim about detour routes, community roads, reopening timing, or any road outside the two reviewed county-strict I-5 intervals. Northbound and southbound conditions can differ, and neither surface makes a safe-to-drive or all-clear claim.
