Mary Carter Greenway Trail closure notice
As part of the C-470 Express Lanes construction project, northbound and southbound Mary Carter Trail will require a full closure to complete demolition work of the South Platte Bridge. The trail will be closed 24/7 beginning mid- June for approximately 2 weeks.
Western detour: Follow the Columbine Trail along Chatfield Avenue and Platte Canyon Road. Take the Mineral Trail along Mineral Avenue to connect back onto Mary Carter Greenway Trail. Detour is approximately 3.2 miles, 0.3 miles longer than original route.
Eastern detours: Follow the High Line Canal Trail to Southpark Lane. Take the Mineral Avenue Trail. After crossing Santa Fe Drive, continue on the Railroad Spur Trail back onto Mary Carter Greenway Trail. Detour is approximately 3 miles, 1 mile shorter than original route.
Follow detour signs accordingly and go slow for the cone zone. Construction activities are weather-dependent and the schedule is subject to change.
The $276 million C-470 Express Lanes project will increase mobility and user choice along 12.5 miles between I-25 and Wadsworth Boulevard. In the westbound direction, two additional Express Lanes will be built from I-25 to Colorado Boulevard and one additional Express Lane from Colorado Boulevard to Wadsworth. In the eastbound direction, one additional Express Lane will be constructed along the length of the project between I-25 and Wadsworth Boulevard. The project also includes full reconstruction of existing pavement, the addition of auxiliary lanes at selected locations, on- and off-ramp improvements, realignment of substandard curves, widening of existing bridges, replacing the bridges over the South Platte River, the installation of tolling equipment and new C-470 trail underpasses at Colorado and Quebec. When complete, motorists will have the option to use the Express Lanes on C-470 for a faster, more reliable commute in exchange for paying a toll, or drive the general purpose lanes for free. Completion is scheduled for 2019.
