VIEW SISKIYOU SUMMIT CAMERAS →Siskiyou Summit on Interstate 5 is the highest point on the entire 1,380-mile west-coast I-5 spine at 4,310 feet per Wikipedia's Siskiyou Summit entry. Located about 4 miles north of the Oregon-California state line near Ashland, Oregon and Weed, California, Siskiyou is renowned for challenging winter conditions — heavy snowfall, high winds, and chain controls. Per Dangerous Roads, the northbound descent drops approximately 2,300 feet over about 6 miles on a 6% grade. ODOT has installed two runaway truck ramps northbound at Mile Post 6.3 and Mile Post 9.5 — gravel-filled escape paths for out-of-control vehicles with brake failure. Snow typically falls November through April, peaking in December with four or more heavy snow days per year. Chain restrictions on I-5 at Siskiyou typically require chains even on vehicles with traction tires — chains on all vehicles except 4WD/AWD unless towing per Rogue Valley Times.

VIEW SISKIYOU SUMMIT CAMERAS →Siskiyou Chain Law — Chains Required on All Non-4WD Vehicles
Per Rogue Valley Times, during chain restrictions on I-5 at Siskiyou Summit, traction tires alone are insufficient — chains are required on all vehicles EXCEPT 4WD and AWD vehicles (unless towing). This is stricter than typical Oregon chain rules elsewhere. Always carry chains November through April on I-5 crossings of Siskiyou — even on 4WD vehicles, you may still need to install chains while towing.
Pro Tip: Siskiyou Is the Primary I-5 Chokepoint
I-5 is the US West Coast freight and traveler spine — from the Canadian border to Tijuana. Siskiyou Summit is its single most significant winter chokepoint. When Siskiyou closes, there is no major freeway alternative — secondary routes (US-97, US-101) add hours. Plan winter I-5 drives between Eugene/Portland and Redding/Sacramento with major buffer time:
- Chains required: Assume at least 60-90 minutes added
- Closure (episodic): Multi-hour waits or detour via US-97 east through Klamath Falls
- Wildfires in summer: Smoke and closures possible

What is Siskiyou Summit's elevation?
Siskiyou Summit is 4,310 feet per Wikipedia — the highest point on the entire 1,380-mile Interstate 5 corridor from the Canadian border to the Mexican border.
When does Siskiyou close?
Episodically during major winter storms. Per Wikipedia, the pass is occasionally closed during winter for severe weather — anywhere from several hours to all day. Chain restrictions are far more common than full closures. Snow typically falls November through April.
Are traction tires enough on Siskiyou?
Not during chain restrictions. Per Rogue Valley Times, when chain restrictions are posted, traction tires alone are insufficient. Chains are required on all vehicles except 4WD/AWD (unless towing). Always carry chains during Siskiyou winter travel.
Are Siskiyou Summit cameras free to view?
Why are there runaway truck ramps on Siskiyou?
Per Wikipedia, the 6% grade and 6-mile northbound descent create brake failure risk for heavy trucks. ODOT installed two gravel-filled escape ramps northbound at MP 6.3 and MP 9.5 to safely stop out-of-control vehicles. These ramps have saved lives — drivers are trained to use them when brake failure occurs.
