Purpose and Need

The Lone Tree Overpass will create a new north-south roadway connection extending Lone Tree Road between Butler Avenue to the south and Route 66 to the north. The roadway will be on a grade-separated bridge that will go over the BNSF Railway main line corridor and the United States Army Corps of Engineers (USACE) future Rio de Flag Channel. Much like the popular Fourth Street railroad crossing constructed in 2006, this new overpass will provide connectivity, traffic congestion relief on streets like Milton Road, San Francisco Street, and Beaver Street, and improved mobility to surrounding neighborhoods. The overpass connection will also complement the community’s need for multi-model options with bicycle and pedestrian access points connecting to the Flagstaff Urban Trail System (FUTS).
