The bridge was designed for a 75-year lifespan. It was built in 1961, meaning it will reach the end of its design life in 2036. Several factors contribute to this lifespan, including that the bridge was never designed for today's volume of traffic. As a result, an increased need for repairs and/or replacement is expected.

The bridge was designed for a 75-year lifespan. It was built in 1961, meaning it will reach the end of its design life in 2036. However, current factors could contribute to a shortened lifespan, including that the bridge was never designed for the current volume of traffic. As a result, an increased need for repairs and/or replacement is expected.
The 10 project objectives are evaluation criteria for the Entrance to Aspen. They were developed by our community in 1994. While the development process for a Record of Decision (ROD) always includes public participation, it is unusual that community-defined objectives are included in a ROD.The Draft Environmental Impact Statement (EIS), on Page I-3 of August 1995, further states:“The objectives were developed based on known problems and concerns related to the State Highway 82 transportation system and corresponding issues raised by the Aspen area community. Consensus on the objectives was developed from the affected agencies, elected officials and staff of area governments, concerned members of the public through a series of individual meetings (community focus groups, open house exhibitions, community leadership workshops) and a technical advisory committee (TAC) consisting of various local governments and state and federal agency staff.”
A number of elements of the Preferred Alternative have been implemented since 1998, including the Maroon Creek Bridge, roundabout, 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, the Main Street bus lane addition, new signals on Highway 82 at Buttermilk, and 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.)
Yes. To ensure this, they will be re-evaluated again by a consultant team, CDOT and FHWA.
