Kozeny-Wagner provided construction services for the Washington Avenue Improvements project. This project included a complete gut and rehab of the historic Washington Avenue, from building to building between Tucker (12th) and 18th Street in downtown St. Louis. Construction included new storm sewers, wider brick sidewalks, trees and grating, architectural paving, granite curbs, custom light fixtures and other amenities.
Kozeny-Wagner discovered dozens of massive, unforeseen vaults that were paved over decades ago. Our team developed innovative solutions to infill and shore the structural voids, some up to 20 feet in depth and 120 feet in width. The majority of the vaults were originally used for coal storage. In addition, nearly every sewer structure, and much of the surface elevations were re-engineered to accommodate the unforeseen conditions.
