I-25 North

Express Lanes - Mead to Fort Collins

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.

I-25 North Express Lanes: 120th to Northwest Parkway/E-470

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.
