As part of a Various Various contract with IDOT District 9, the District assigned TWM a work order to rehabilitate the bridge carrying I-24 over the Ohio River. The mile-long bridge spans from Massac County, Illinois to McCracken County, Kentucky and consists of continuous 2-girder units and two tied arch spans over the navigation channels.

The project is in the final stages of design and will be completed using four stages of construction to allow for one lane of traffic in each direction throughout construction and to allow the contractor to overlay both eastbound and westbound lanes at once. The rehabilitation will extend the bridge’s service life by 15 to 20 years, ensuring continued safe and efficient transportation across this vital interstate connection.

Scope of Work

  • Replace finger plate joints with modular joints to accommodate expansion lengths of up to 1,500′, allowing for total movement of approximately 20″

  • Clean and paint steel components near the deck to prevent corrosion

  • Repair deck surface and parapet defects

  • Apply a microsilica concrete overlay to extend deck life, followed by diamond grinding for a smooth riding surface

  • Extend outside parapets and add a glare screen to the median barrier to enhance safety
