Econolite -Sole Source Letter 2026.pdf

This is a sole source authorization letter from Econolite Control Products, Inc. confirming that Traffic Control Corporation is the exclusive authorized distributor for all Econolite products and services in Missouri. The letter, dated January 1, 2026, establishes Traffic Control Corporation as the only approved source for Econolite's complete product line, which includes Cobalt NEMA and Rackmount series controllers, Safetran brand products, traffic signal and pedestrian signal hardware, detection systems, cabinet assemblies, and electronic components. The Missouri Department of Transportation, St. Louis District has determined that only Traffic Control Corporation can provide warranty support and repair services for existing Econolite equipment currently installed in the district. The contract period extends from execution through August 31, 2027, with options to renew for two additional one-year periods.

The sole source determination is based on the complete compatibility of Traffic Control Corporation's offerings with all current Econolite systems installed in the St. Louis District. Repairs performed by unauthorized facilities could void manufacturer warranties and compromise system functionality. This single feasible source designation meets Missouri's posting requirements for one calendar year in connection with the documented service and product needs. No pricing terms, bidding process, or competitive procurement is applicable given the sole source nature of the authorization.
