I-25 North Forty
The North Forty transportation project on Interstate 25 encompasses 14 miles of the state’s high-priority transportation projects, as well as an Environmental Impact Study (EIS) of an additional 26 miles of highway.
Construction projects along this corridor have and will include interchange reconstruction, highway widening and capacity improvements that will accommodate multi-modal transportation improvements well into the future. Currently no construction is underway.
