UNSPSC 46161500: Traffic control

UNSPSC 46161500 Traffic control, a Class code, encompasses pavement marking, line striping, traffic signal equipment installation and maintenance, and road salt procurement—work state and local governments solicit across cities, counties, townships, and transit authorities. Recent opportunities show municipalities purchasing treated rock salt for winter maintenance (Milford Township, Pennsylvania), line painting and pavement markings on 350+ miles of roadway (Orange County, California), traffic signal equipment upgrades and retiming (Lewisburg Borough, Pennsylvania; York City, Pennsylvania), on-call signal maintenance services (City of Stamford, Connecticut), and street sign replacements (Union City, Georgia). The issuing-body mix spans townships (Milford, Penn Forest, West Rockhill, Honey Brook, Upper Nazareth, Caln, Exeter), boroughs (Millersburg, Lewisburg, Penndel, West Leechburg), county public works departments (Orange County California, Mifflin County), cities (York, Lancaster, Harrisburg, Stamford), and the Massachusetts Department of Transportation. Pennsylvania dominates recent activity with road paving, sealcoat, and line-marking solicitations across Bucks, Chester, Lancaster, Luzerne, Schuylkill, Dauphin, Carbon, Montgomery, and Cumberland Counties, alongside activity in California, Massachusetts, Connecticut, Georgia, and Florida.

Representative recent opportunities include Orange County Public Works (orange County, California) requesting competitive bids for traffic marking services covering approximately 350 miles of unincorporated and contracted-city roadways, with an initial five-year term and 81 line items for pavement striping, curb markings, and raised pavement markers, bids due July 21, 2026 via IFB; Milford Township (Pennsylvania) issuing sealed bids for 200 tons of Type 2 LMC organic-based bulk rock salt and 300 tons of standard rock salt for winter road maintenance, bids due July 20, 2026 via IFB; Lewisburg Borough (Pennsylvania) seeking electronic bids for traffic signal retiming and equipment upgrades across five signalized intersections on Market Street, including NEMA TS-2 controllers, emergency preemption systems, signal heads, and conduit infrastructure, bids due July 1, 2026 via PennBid; and the City of York (Pennsylvania) requesting sealed bids for the Bridge 358 Superstructure Replacement project involving bridge reconstruction and traffic control, with bids due May 27, 2026 via PennBid. Prevailing wage requirements apply to most Pennsylvania-based work; California enforces prevailing wage compliance with active District Attorney enforcement. The code shows consistent small-ticket to moderate-value activity across maintenance, capital improvements, and on-demand services, with most opportunities concentrating in the Northeast and California.
