Please visit our page on the North I-25 Express Lanes Project for the most current travel updates. The I-25 North Express Lanes Project: Berthoud to Johnstown section will increase highway capacity by adding an Express Lane in each direction, rebuild interchanges, replace aging bridges, straighten highway curves to improve safety, make major utility and drainage improvements, and add carpool and transit facilities. During construction on the I-25 North Express Lanes Project, motorists should expect speed reductions to 65 mph, minor lane shifts, temporary concrete barriers and median bridge work. Motorists should also expect delays during the scheduled work hours. Construction on the Berthoud to Johnstown segment is expected to be complete in early 2024.
