Gila Catwalk Trail Reconstruction

NV5, as a subcontractor to the design-build team of AUI, Inc. and Bohannan Huston, Inc. (BHI), performed the environmental permitting (EPA 401/404), geotechnical investigation & design, and construction materials testing for the Gila Catwalk Trail reconstruction project. The design-build project was awarded in August of 2015, design was completed around Christmas 2015, construction began the second week of January 2016 and was complete by Memorial Day 2016.

Located in a remote slot canyon, the Catwalk Trail was built in 1933 by the Civilian Conservation Corps and designated a National Recreation Trail in 1978. In 2012, the Whitewater/Baldy Fire burned over 290,000 acres near the Catwalk Trail. In 2013, record rainfall flooded Whitewater Canyon, destroying the historic Catwalk.

The reconstruction project included design and construction of three bridges; 700 feet of cantilevered, rock-bolt-supported, catwalk in the overhanging, narrow, slot canyon; stabilization of an oversteepend slope made up of altered rock and soil; and trail improvements employing gabion baskets. The project also included trail restoration, creek & structures cleanup, erosion control, historical & archeological preservation, and parking lot rehab. Tourism in the area has been rejuvenated dramatically, and the project has received international attention.
