See the summit before you drive it. Live ODOT cameras and real-time conditions on I-5 over Siskiyou Summit — the highest point on the entire Interstate 5, and the winter wildcard between Oregon and California.
Siskiyou Summit carries I-5 over the Siskiyou Mountains at 4,310 ft. Here's what to watch, and when it bites.
If any part of I-5 is going to close in winter, it's usually here. At 4,310 feet, Siskiyou Summit gets snow and ice that shut the interstate or force chain requirements several times a season — and because it's the only I-5 crossing of this range, a closure here backs up traffic for hours in both states.
Siskiyou Summit is the highest elevation on all 1,381 miles of Interstate 5, from Canada to Mexico. That's why it, and the Grapevine far to the south, are the two spots drivers actually have to plan around in winter. Southbound, it's the last climb before the long drop into California.
