Gold: West 6th Avenue Viaduct RehabSubmitted by Edward Kraemer & Sons Inc. The West 6th Avenue Viaduct Rehabilitation completely removed and replaced the substructure elements of the westbound viaduct in Denver. Also included were replacement of three expansion joints, improvements to drainage and replacing 900 sq yd of bridge deck on the eastbound viaduct.
The many challenges included working with limited vertical clearance within an active railroad maintenance facility and in close proximity to live light-rail tracks, managing traffic throughout construction and lifting the bridge to rest on temporary and new permanent structures.
