At the time that this unusual tunnel was dedicated in 1930, it was the longest tunnel of its type in America. Oversized vehicles get assistance through this tunnel with the help of rangers stationed in what National Park?

This is the Zion-Mt. Carmel Tunnel, so-named for its location within Zion National Park and its proximity to the Mt. Carmel junction. The tunnel was originally built so that drivers could have access to Bryce Canyon and Grand Canyon from Zion National Park.
