“Earth Day is an excellent opportunity to demonstrate how states are taking a wide-ranging approach to responsible environmental stewardship,” says Bud Wright, AASHTO executive director. “In our video Hawaii DOT is seen working across jurisdictional lines to reach statewide sustainability targets. And the examples presented here are but a handful of the ways state DOTs are working to preserve and protect the environment.”
AASHTO also produced a summary sustainability efforts by other state DOTs. These include:
Michigan DOT LED lighting project
The Michigan Department of Transportation began this month replacing the first of more than 15,000 outdated and inefficient highway light fixtures and bulbs in the metro-Detroit area.
The work is being done under a first-of-its kind public-private partnership agreement signed last fall between MDOT and Freeway Lighting Partners. The installation project will be completed late next year. MDOT estimates that over contract’s 15-year term, Michigan taxpayers will save an estimated $13 million in energy costs.
