Colorado State Highway 82 provides the primary access into Aspen. The highway crosses the wide and deep Maroon Creek basin on the oldest bridge in service on the state highway system. Originally constructed as a railroad trestle bridge in 1888, the Maroon Creek Bridge was converted for highway use in 1929 and currently has the lowest sufficiency rating in the state.

Parsons was selected by the Colorado Department of Transportation for the design of a Maroon Creek replacement structure and given the notice-to-proceed for design in September 2004.
 
The project required a fast-track schedule to meet the March 2005 bid date required for funding reasons. The design was required to follow the 1998 “State Highway 82, Entrance to Aspen, Record of Decision.” This stipulated that the design of the replacement bridge not only meet the needs of the S.H. 82 transportation improvement project but also complement the historic look of the existing bridge and be constructed with minimal impact to the wetlands in the deep creek basin.
 
Preliminary design studies determined a safe, cost-effective, environmentally friendly and aesthetically pleasing bridge structure. The recommended alternative for a single-cell, cast-in-place concrete segmental box girder was approved unanimously, meeting all of the project design requirements.

 The 620-ft-long structure features a 270-ft main span 100 ft above the Maroon Creek basin, supported by A-shaped piers developed to complement the design of the existing historic bridge.

The new bridge is 73 ft wide, including a 12-ft pedestrian and bike path. The structure section is a constant 13 ft, 6 in. deep, with 19-ft-long deck overhangs, using ribbed elements for support. The concrete box girder is constructed from above in balanced cantilever, using form travelers to protect the environmentally sensitive and difficult access area below the bridge.

The project was awarded for construction in June 2005 for $13.97 million, and the bridge is scheduled for completion in November 2007.
