SPRINGDALE – Zion National Park will be using a digital 3-D scanner to map the inside of the Zion-Mount Carmel Highway Tunnel to assess its condition. Visitors through the tunnel should expect 20- to 30-minute delays due to tunnel closures on weekdays from March 12-27.
The tentative project schedule is as follows:
- March 12 – The tunnel will be closed three times for approximately 20 minutes each
- March 16-20 – From 6-8 a.m., the tunnel will be closed for up to 25 minutes at a time
- March 23-27 – The scanning may be finished by this time, but if not, it will continue on the same 6-8 a.m. schedule as the week before
The park’s cultural resources staff leased the 3-D laser scanners in order to create a digital 3-D model of the tunnel. Using this model, the park will be able to document the tunnel construction materials and methods in a way that would be impossible through any other means without closing the tunnel for extensive periods of time. The digital 3-D model of the tunnel may then be used to assess the condition of the tunnel, assess any damage, obtain measurements of tunnel elements, and assist in park planning.
