Design and Construction
OTIA III Bridge Program
The OTIA III Bridge Delivery Program is using the innovative Context Sensitive and Sustainable Solutions (CS³) approach to build a new generation of bridges. Various aspects of the OTIA III Program support greenhouse gas reductions and thus climate change mitigation:
  • The OTIA III Access/Staging Performance Standard limits truck idling to five minutes, except in extreme cold weather or when needed for other reasons.
  • The OTIA III Materials Procurement and Use Performance Standard requires contractors to use ultra-low sulfur fuel, bio-diesel, or EPA-verified fuel additives in vehicles and equipment where possible and available, or minimum of highway grade fuel where alternative fuels are not possible.
  • The OTIA III Materials and Contamination Performance Standards require extensive reuse and recycling of bridge materials.
    • For example, in 2009; 44,800 tons of asphalt pavement, 21,500 tons of clean fill, 40,200 tons of concrete, 2,700 tons of metal, and 400 tons of wood were captured, reused, and recycled.

CS³ Guidebook explains ODOT’s CS³ approach, initiated in the OTIA III State Bridge Delivery Program, and how the process can be applied to other projects.

ODOT is currently in the process of evaluating three pilot projects, in various levels of completion, based on the Greenroads sustainability performance metric. Greenroads was developed out of the University of Washington in consultation with CH2M HILL. The Greenroads performance metric awards points for more sustainable practices during the design and construction phases of roadway projects and awards a certification level based on the number of points earned, much like the LEED program does for buildings.
