CO 402 Under I-25 Closed Until Completion in October

By the end of 2019, the I-25 and Colorado Highway 402 interchange will undergo substantial changes, resulting in a new and improved interchange. To support reconstruction, the I-25 North Express Lanes Project team closed eastbound and westbound CO 402 under I-25, as well as the southbound I-25 on- and off-ramps to the new Southeast Frontage Road, for 120 days. Once completed in October, the new configuration at CO 402 will be fully operational, and future impacts at this interchange will be minimal. For detour information, visit:
