About the Eisenhower Tunnel

When Colorado asks "is I‑70 open," this is the stretch it means: the mountain corridor from Floyd Hill west of Denver, up through Idaho Springs and Georgetown to the Eisenhower–Johnson Memorial Tunnel — 11,158 feet under the Continental Divide, the highest point on the entire Interstate system — then down to Silverthorne and Dillon, past Copper Mountain and over 10,662‑foot Vail Pass into Vail.

The drive is ski country's main street: Loveland at the tunnel's east portal (exit 216), Arapahoe Basin and Keystone via US‑6 from the Silverthorne/Dillon exits, Breckenridge down CO‑9 through Frisco (exit 203), Copper Mountain (exit 195) and Vail (exit 176). That geography writes the traffic pattern — on peak winter Saturdays the tunnel meters westbound traffic into 90‑minute queues by 9 a.m., and Sunday afternoons jam the eastbound side coming home.

The banner above the cameras reads CDOT's live COtrip feed, the same data behind the roadside chain-law signs. Colorado's rules arrive as numbered codes: the Passenger Traction Law (Code 15 — snow-rated tires, 4WD/AWD with adequate tread, or chains) and the Passenger Chain Law (Code 16 — chains or traction devices on every passenger vehicle, the last step before closure), plus the commercial chain laws (Codes 17 and 18); commercial drivers must carry chains on this corridor from September 1 through May 31. The cameras run east to west in drive order, Floyd Hill to Vail.

Driving the Eisenhower Tunnel in winter

  • Leave Denver before about 6:30 a.m. on winter Saturdays — tunnel metering can add 90 minutes by mid-morning, and the cameras show the queue forming long before the apps do.
  • Code 15 often activates corridor-wide before snow reaches your windshield — check the banner, not the sky, and remember the fines apply if you spin out unequipped.
  • Vail Pass chains up and closes separately from the tunnel — a clear tunnel frame doesn't clear the whole drive, so scan the Vail Pass summit and chain-station cameras before committing past Copper Mountain.
  • Hazmat trucks are banned from the tunnel and cross 11,990‑foot Loveland Pass on US‑6 instead; when that closes, CDOT escorts them through the tunnel in convoys — the sudden, unexplained holds the cameras sometimes show.
  • Continuing west past Vail? Glenwood Canyon closes for rockfall and mudslides with little warning — check the I‑70 Mountains map at /cdot-cameras/i-70-mountains, and confirm everything official on COtrip.org or by dialing 511.

Frequently asked questions

Is I-70 open through the mountains right now?
The banner at the top of this page shows the live corridor status — open, traction law, chain law, or closed — from CDOT's COtrip feed, and the cameras show the pavement from Floyd Hill to Vail. Official closure orders and reopening estimates are on COtrip.org or by dialing 511.
What are Colorado's Codes 15, 16, 17 and 18?
Code 15 (Passenger Traction Law): snow-rated or mud/snow tires, 4WD/AWD with adequate tread, or chains. Code 16 (Passenger Chain Law): chains or approved traction devices on every passenger vehicle — rare, and the final step before the road closes. Codes 17 and 18 are the commercial chain laws: Level 1 chains single-drive-axle combinations first, Level 2 chains every truck on the road.
How high is the Eisenhower Tunnel?
11,158 feet — the highest point on the Interstate system and its longest mountain tunnel, roughly 1.7 miles under the Continental Divide. The westbound Eisenhower bore opened in 1973, the eastbound Johnson bore in 1979.
Why is traffic stopped at the tunnel when nothing looks wrong?
Safety metering: the bores have two lanes and no shoulders, so CDOT stops traffic outside rather than let a queue form inside — routine on ski-season Saturday mornings westbound and Sunday afternoons eastbound. The other cause is a hazmat convoy: tunnel-banned trucks get escorted through when Loveland Pass is closed.
What about Vail Pass?
10,662 feet between Copper Mountain and Vail, with steep grades on both sides — it ices, chains up and closes independently of the tunnel, and it's routinely the last section to reopen after a storm. Treat the tunnel and the pass as two separate questions the cameras answer one after the other.
Where's the rest of Colorado?
The I‑70 Mountains map at /cdot-cameras/i-70-mountains widens the view to Loveland Pass, Berthoud Pass and Glenwood Canyon, and the statewide map at /cdot-cameras has all 900‑plus CDOT cameras. Continuing west, /udot-cameras picks up I‑70 across Utah's San Rafael Swell — 100‑plus miles with no services.
