The views show the approach to the tunnel on the Chamonix side. Waiting times, the direction of traffic and closures are published by the operator: this page does not show them.
In short. The Mont Blanc Tunnel links Chamonix with Courmayeur over 11.6 km (source: ATMB). Savoie Snow has no traffic data: the waiting time at the toll, the direction of traffic and closures are published on ATMB’s official page. The views and weather on this page describe the approach to the tunnel, not the traffic.
This page brings together 2 views: Tunnel du Mont-Blanc and Chamonix-Mont-Blanc-Rampe du Tunnel du Mont-Blanc, vue orientée vers Chamonix. They let you see the approach to the tunnel and the sky above Chamonix, not the queue at the toll.
The tunnel is regularly closed at night or for maintenance. These closures are announced by ATMB on its traffic page; the schedule should be read at that source, for the date of your journey.

Text of this page last revised on . This date says nothing about how recent the images or data are: the webcams are supplied by the credited operators and their timestamp shows when the image was taken; model forecasts and official reports are separate pieces of information, each with its own time. The forecast applies to the point and altitude shown in the weather block.
