I-25 North

Expanding I-25 with an Express Lane in each direction, this project will provide trip reliability, safety improvements and more for Northern Colorado, and will do it about 15 years earlier than originally expected.

The goal of the I-25 North Express Lanes: 120th to Northwest Parkway/E-470 project is to increase mobility and travel choice along a six-mile segment of I-25 by building an Express Lane in each direction of a highway that connects downtown Denver to major growth in northern Colorado.

Expanding I-25 from Denver to Wyoming has been in the works for years and there's lots more to come. See where we have been and where we are going.
