UNSPSC 95121629: Railway viaduct

A bridge of several small spans used to span an obstacle for the purpose of allowing railways to traverse the obstacle

UNSPSC 95121629 Railway viaduct (Commodity) represents intelligent transportation system infrastructure and safety detection work at roadway viaducts experiencing over-height vehicle strikes and flooding, based on recent state and local solicitations that diverge substantially from the code's nominal scope. The Henry County Water Authority, Orange County Florida, and Louisville/Jefferson County Metro Government have posted bids for projects that span pump station construction, bridge replacement, security systems, and viaduct-monitoring technology, but the most decision-relevant recent activity clusters around two Via-Smart demonstration projects funded through federal SMART grants—one with Louisville Metro (IFB260244, posted May 5, 2026, due May 19, 2026) and another (IFB260165, posted March 25, 2026, due April 16, 2026)—both procuring detection devices, signage, traffic control equipment, cameras, conduit systems, LIDAR and infrared sensors, and web relay controllers to transmit real-time information about flooding, approaching over-height vehicles, and confirmed strikes to the public and government agencies at four identified viaduct intersections across Jefferson County.

The code shows sparse and scattered recent activity concentrated in two states. Georgia and Florida dominate the posting volume with water authority pump station work (Henry County Water Authority, City of Tallahassee, City of Palm Bay) and bridge replacements (Orange County), while the Kentucky viaduct-safety projects represent the only direct match to the code's infrastructure monitoring purpose. Colorado, California, South Carolina, and Texas show secondary activity focused on utility relocation, drainage improvement, sidewalk replacement, and stream restoration—work that is not aligned with railway or roadway viaduct systems. The Louisville Metro Via-Smart Project is the clearest representative opportunity under this code, requiring prequalification with the Kentucky Transportation Cabinet, minimum 30 percent self-performance, Davis-Bacon compliance, and a five percent bid bond, with award to the lowest responsive and responsible bidder and performance and payment bonds equal to 100 percent of contract price. No other recent solicitions in the block are substantively tied to viaduct infrastructure; the code itself appears underutilized or inconsistently tagged across state and local procurement systems.
