The Record of Decision was intended as a phased approach. Elements that have been completed as of 2022 include:
- Maroon Creek Bridge.
- Pedestrian overpasses over Maroon Creek and Castle Creek Roads.
- Harmony Road underpass and intersection improvements.
- Owl Creek Road realignment and new signals at Highway 82 at Buttermilk Mountain.
- Main Street bus lane addition.
- New signals on Highway 82 at Buttermilk.
- Conveyance of right-of-way. In 1996, Aspen voters approved an easement across Marolt-Thomas Open Space for two lanes and a light rail in exchange for Mills Ranch property as open space.
- Transit Management Program. Programs and policies encourage people to use the bus, bike, or walk.
In addition, the City of Aspen implemented additional programs with the intent of increasing the use of alternative modes of transportation. These include:
- Main Street bus lane.
- Roaring Fork Valley vehicles car share program.
- Carpool matching and parking programs.
- Transportation Options Program that provides grants and other benefits to employers.
The next phase of the ROD is the Highway 82 realignment and a new Castle Creek Bridge.
