Coverage details
Covers reported SR-140 conditions from listed sources — some nearby roads aren't monitored. See what's included.
This page shows full-road conditions reported by MountainSwitch's listed SR-140 sources, including District 10 feed rows outside the reviewed Mariposa / El Portal approach.
Those route-wide reports don't expand the Mariposa / El Portal destination verdict. That verdict covers the reviewed SR-140 approach from Mariposa through Midpines and El Portal to the Caltrans state-route endpoint at the Yosemite park boundary. National Park Service-managed El Portal Road and other in-park roads are separate authority surfaces; SR-120 west and SR-49 are context only and never part of the destination verdict.
Conditions can change quickly in the mountains. This page never replaces chain requirements, closures, or official Caltrans guidance. This boundary supports no destination-access claim beyond the reviewed SR-140 approach and no claim about in-park roads, context-only routes, reopening timing, or roads outside MountainSwitch's listed sources. Neither surface makes a safe-to-drive or all-clear claim.
