During the summer and fall of 2007, construction of 2 multi-use pathways took place for Teton County, Wyoming. Included in the process was the construction of a keystone retaining wall as well as the creation of additional wetlands next to Flat Creek. Approximately 2,700 feet of the project occurred adjacent to State Highway 22 (one of the busiest roadways in the state). Further complicating matters, another 600 feet of pathway had to be constructed over existing wetlands. Once completed in the spring of 2008, total costs for the projects exceeded $500,000.
