Bridge Preventative Maintenance for 10 Structures in Region 4

This project involves preventative maintenance work on ten bridge structures located in Region 4 of Colorado, with a focus on enhancing the durability and safety of these structures over I-70. For structures G-22-BD and G-22-BE, the work includes removing the existing concrete deck topping, performing Class 2 and 3 removals, and applying a polyester concrete overlay to extend the lifespan of the decks. The remaining eight structures, which carry county roads over I-70, will undergo removal of their existing hot mix asphalt (HMA) deck toppings, followed by necessary repairs, waterproofing membrane installation, and overlaying with HMA using a specified mix (SX)(75)(PG 64-28). The project aims to improve the structural integrity and waterproofing of these bridges to prevent future deterioration. The contract is valued between one million and five million dollars and is managed by the Colorado Department of Transportation.
