Thane Road Avalanche Hazard Reduction and Closure Notices

January 14, 2026

Thane Road is now OPEN. Drivers are reminded not to stop in the avalanche zone. Thank you for your patience and understanding during the closure.

January 13, 2026

Thane Road will be closed at the avalanche gates today, Tuesday, 1/13 at 12:00 pm (noon) due to high avalanche hazard to the roadway. This emergency closure will be re-evaluated at 6:00 a.m. on Wednesday, 1/14. If a natural avalanche reaches the roadway, DOT&PF may not be able to safely remove avalanche debris until conditions improve through mitigation work or a natural decrease in avalanche hazard.

January 8, 2026

Thane Road will be closed at the avalanche gates Friday, Jan. 9, 2026 at 12 p.m. (noon) due to high avalanche hazard to the roadway. This emergency closure will be re-evaluated at 8 a.m. on Saturday, Jan. 10.

The avalanche hazard is expected to remain high over the next few days. If a natural avalanche reaches the roadway, it is unlikely DOT&PF will be able to safely remove the avalanche debris until the hazard can be minimized from mitigation work or once the hazard has decreased naturally.

Thane residents should be prepared for the possibility of extended road closures. Please visit the CBJ emergency management site for personal and household preparedness details.

December 31, 2025

DOT&PF plans to conduct avalanche hazard reduction above Thane Road tomorrow, Thursday, Jan. 1, between 11:00 AM and 2:00 PM (weather dependent).

Thane Road will remain closed at the avalanche gates until hazard reduction work is complete and conditions allow for a safe reopening.

This work is intended to reduce the risk of larger avalanches impacting Thane Road. If avalanche debris reaches the roadway, an extended closure may be necessary to safely remove debris.

Updates will be posted on 511.alaska.gov, on this page, and on the DOT&PF Facebook page.

December 31, 2025

Thane Road remains CLOSED at the avalanche gates due to continued high avalanche hazard to the roadway.

DOT&PF crews are continuing to assess conditions. We will provide an updated status around 12:00 PM today.

Updates will be posted on 511.alaska.gov, on this page, and on the DOT&PF Facebook page.

December 30, 2025

Thane Road will be closed at the avalanche gates today, Tuesday, Dec. 30, at 8:00 p.m. due to high avalanche hazard to the roadway. This emergency closure will be re-evaluated at 8:00 a.m. on Wednesday, Dec. 31.

The avalanche hazard is expected to remain high over the next few days. If a natural avalanche reaches the roadway, DOT&PF may not be able to safely remove avalanche debris until the hazard can be minimized through mitigation work or once conditions decrease naturally.

Thane residents should be prepared for the possibility of extended road closures. Please visit the CBJ emergency management site for personal and household preparedness details.

DOT&PF is monitoring conditions closely and will provide updates as needed.

December 26, 2025

There is potential for heavy snowfall, strong winds, and warming at higher elevations over the next several days (December 27-30, 2025). These conditions may rapidly increase avalanche hazard above Thane Road and increase the likelihood of an avalanche reaching Thane Road.

DOT&PF reminds all travelers to obey posted warning signs. Do not stop or park in the avalanche zone. If Thane Road is blocked by avalanche debris, it is unlikely DOT&PF will be able to safely clear the road until conditions allow mitigation work or the hazard decreases naturally.

Thane residents should be prepared for the possibility of extended road closures. Please visit the CBJ emergency management site for personal and household preparedness details.

DOT&PF is monitoring conditions closely and will provide updates as needed.

Here’s how DOT&PF will typically share information out to the Thane residents about potential road closures:

  1. Early notification typically uses the orange avalanche control signs on Thane Road.
    • If DOT&PF is planning an avalanche hazard reduction mission, we will try to have those signs updated as soon as we anticipate needing a mission.
    • So, the signs could be updated a day or two (as conditions allow) in advance of a mission.  
       
  2. The second notification goes out via a GovDelivery alert within 24 hours of a potential road closure.
    • Once the GovDelivery alert is sent, it is highly likely that a road closure/hazard reduction mission will occur.

By using the warning signs, DOT&PF can give Thane residents a heads up that a mission will likely occur. Once the GovDelivery alert is sent, a mission is planned and residents should expect a road closure.

Because the avalanche hazard mitigation work depend on changing snow conditions and weather, it’s possible that DOT&PF uses the signs or both signs and alerts, then calls off the mission.

DOT&PF recommends that all Thane residents sign up for GovDelivery alerts and share sign up info widely.
