Change Order Notice I-25-2013 Tri-State Tollway (I-294) Drainage Improvements at 75th St Interchng

Illinois Tollway Authority (operating the Tri-State Tollway, I-294) issued Change Order Notice I-25-2013 on October 7, 2026 for drainage improvements at the 75th Street Interchange; this is the First Amendment to an existing contract, not a new solicitation. The notice was posted with an October 22, 2026 date, though this appears to mark document availability rather than a response deadline, as change orders notify the incumbent of approved modifications to contract terms, scope, or pricing rather than solicit competitive bids. The attached change order document (2013-Change Order Notice V.25.1.pdf, 1MB) contains specifics on cost adjustments, schedule modifications, and scope changes to the original drainage improvement agreement at the I-294 corridor. Interested parties should review the attached document for full details on the modifications and their effect on the existing contract.
