The Mary Carter Greenway is one of the busiest regional multi-trails in the metro area with over 300,000 recorded trail users annually within South Platte Park. Spanning 8.25 miles from C-470 to Hamilton Place, the trail crosses through the cities of Littleton, Englewood, and Sheridan. In the fall of 2022, South Suburban and Arapahoe County Open Spaces kicked off a study to identify potential improvements to enhance access and experience for trail users. The completed study can be found below in the news feed. This study identified the Mineral Avenue Bridge Realignment and the South Platte Park East Trail Bridge Replacements as priority projects. The second phase of the Mary Carter Greenway Trail Study will take these select projects through the design process to produce construction drawings.
