Cheyenne, WY

Client:  City of Cheyenne

At $28 million, the Norris Viaduct project is the largest public works project undertaken by the City of Cheyenne to date. The Norris Viaduct connects south and north Cheyenne over the Union Pacific Railroad and replaced a structure built in 1952, which had deteriorated to the point that required replacement. The project encompassed the two span steel box girder bridge, as well as, a pedestrian underpass, street realignments (Logan Ave., 6th Street, Campstool, and 5th/Morrie Ave, Cheyenne, WY), storm sewer (2,500’), water and sewer mains (9,000’). Special Design elements and aesthetic enhancements incorporated in the bridge design included MSE walls, and decorative bridge treatments (railing, lights, and wall patterns) street improvements with landscape amenities, pathways, and shelters.

AVI personnel working on this project have provided excellent service and good responsiveness. Very much team players and valuable as resources.

Marcia Murdock, AML Project Manager

AVI completed a very good report, detailing multiple surfacing options and developed cost estimates for each option — good job!

Kevin Stogsdill, PE-WYDOT Interstate 80 RECON

I was very impressed by the timely efforts including straightening out the problem R/W survey that had stalled the project for years.

Dan Lyons, PE-WYDOT Veteran Road

AVI is one of our best consultants. They have proven they can handle multiple projects at one time. WYDOT would be hard pressed to give AVI a project they could not handle.

Cliff Spoonemore, PE-WYDOT Snowy Range Road

I was impressed with your knowledge of the reporting requirements and processes, as well as how well you prepared for the pre-bid meeting and pre-construction meeting.
