Northern Corridor Freeway - Washington County

from: Smart Choices, Less Traffic: The 50 Best and Worst Transportation Projects In the United States, Sierra Club Beyond Oil Campaign, November 2012

This proposal is for a freeway through the Red Cliffs Desert Tortoise Reserve and Bureau of Land Management's Red Cliffs National Conservation Area in Washington County, Utah. The stated purpose of the road is to reduce congestion on east-west corridors in the region. The Northern Corridor is in direct conflict with the terms of the Habitat Conservation Plan enacted in 1996 to protect the threatened desert tortoise whose Mojave population is in continued decline. If the road were to bisect the habitat, it would not only degrade the tortoise habitat, but also establish an undesirable precedent undermining Habitat Conservation Plans nationwide. The tortoises would face additional stresses, including light, noise, vibration, vehicle traffic, habitat fragmentation, and degraded air quality. This project was first proposed in the early 2000s and its environmental assessment was rejected in 2009 by the US Fish and Wildlife Service. However, UDOT is currently in the process of pursuing a feasibility study for the project.
