I-70 Rural Bridge Rehabilitation

About the Project

Bridge preventative maintenance work will occur just east of Limon on a 33-mile stretch from Limon to Flagler, Mile Points 362 to 394.5. The phases of the bridge preventative maintenance project will be:

  1. Structure G-22-AX on CR 28/I-70 Frontage Road and structure G-23-AM on CR 36/Bovina exit from late June 2025 to July 2025
  2. Structure G-24-Z on CR 3/I-70 Frontage Road and structure G-24-Q on CR 5/Flagler exit from late July 2025 to October 2025
  3. Structures G-22-BD and G-22-BE on I-70 over the Kyle Railroad. Full closure of I-70 is necessary for the safety of the traveling public and the integrity of the structure.

The above order of construction maintenance of structures is tentative and dates and this schedule is subject to change.

The work will include:

  • Removing the existing concrete deck topping or hot mix asphalt
  • Receiving a polyester concrete overlay or waterproof membrane and hot mix asphalt overlay.

The preventative maintenance work will feature repairs to the existing bridge deck and expansion joints, improving the bridge's durability. The maintenance will also feature new overlays, including Polyester and Asphalt, designed to increase the lifetime of the bridge decks.
