Staying environmentally responsible

MoDOT is making significant efforts on staying environmentally responsible during the construction and maintenance of the roads and bridges throughout the state. On the I-64 project, much of the concrete removed from the highway will be reused as part of the roadbed for the new concrete. In five years, the department across the state kept more than $3.6 billion pounds of waste from going into landfills (about the amount of household waste generated each year by the entire metropolitan St. Louis area). MoDOT reclaims about 70 percent of the state highway signs for re-use and uses recycled glass beads to increase the reflectivity of the roadways. In 2007, the department received an award from the Missouri State Recycling Program for its landmark efforts.
