The Missouri Department of Transportation's Central District is issuing an Invitation for Bid (IFB) for traffic signal upgrades at the intersection of Highway 21 and Route E in Potosi, Missouri, located in Washington County. The procurement seeks a contractor to upgrade signal equipment in all four directions, converting existing 5-section heads to 4-section flashing yellow arrows with the addition of left turn yield on flashing yellow arrow signs, and adding a 3-section head to the upright post for straight-through signals in all four directions with high visibility back plates. MoDOT will provide all materials, and the awarded contractor must be responsible for traffic control in accordance with Section 3.8 of the Special Terms and Conditions, with work to be performed during non-peak traffic hours and in compliance with current Missouri Standard Specifications for Highway Construction. Bids are due electronically through MissouriBUYS powered by MOVERS by February 11, 2026, at 8:00 PM Central Time, with no pre-bid conference or site tour specified.
