NIGP 550: Markers, Plaques and Traffic Control Devices

NIGP 550 Markers, Plaques and Traffic Control Devices, a Class code, encompasses the physical infrastructure and signage that municipalities, counties, and transit authorities install and maintain to manage roadway traffic, pedestrian safety, and work-zone operations. State and local governments procure traffic signal equipment, pavement markings, delineators, message boards, barriers, signs, and associated installation services under this code in volumes ranging from routine supply orders to major infrastructure projects. The issuing bodies span city public works departments, county boards of commissioners, state departments of transportation, and special-purpose districts across the country, with recent activity heavily concentrated in Florida and Texas. The code sees steady activity across equipment supply (standalone purchases of signal heads, markers, or portable message systems), installation and construction services (traffic signal systems, pedestrian hybrid beacons, intersection improvements), and maintenance-of-traffic services (temporary control during utility work or emergency operations).

Recent opportunities show a diverse mix of procurement types and scales. The State of Texas is requesting bids on high-impact plastic traffic markers with UV-resistant coatings and reflective properties to read "CALL BEFORE YOU DIG" and "VALVE" (due July 17, 2026). Okaloosa County, Florida issued an ITB for maintenance of traffic and pavement markings under FDOT prequalification, covering 124 line items of temporary and permanent traffic control devices (due August 5, 2026). Orange County, Florida is accepting sealed bids for supply and installation of traffic signal equipment under a five-year term estimated at $20 million (due July 21, 2026). The City of Milpitas, California is conducting a five-year blanket-purchase-order IFB for MRO supplies including traffic control equipment across multiple categories, with local vendor preference applying (due August 4, 2026). The New Hampshire Department of Transportation sought bids on a skid-mounted variable message board with full-matrix LED display and wireless control (due July 28, 2026). The City of Detroit requested quotations for 5,000 traffic delineator posts meeting NCHRP Report 350 Category 1 standards and Reflexite reflective sheeting (due July 2, 2026). Harris County Toll Road Authority solicited bids on concrete traffic barrier services (due July 20, 2026). Geographic concentration reflects heavy procurement activity in Florida counties (Orange, Okaloosa, Hillsborough, Seminole), Texas (Houston, Dallas, Harris County, Austin-area), California (Santa Clara, Milpitas), and New Hampshire state government, with scattered activity across the Midwest and Northeast. The code represents active, recurring demand across all levels of local government.
