US 34 bridge reconstruction requires full closures overnight at I-25 Tuesday night

Travel Advisory

March 18, 2022 - Northeastern Colorado

Loveland – I-25 widening and US Highway 34 bridge reconstruction continues as the Colorado Department of Transportation progress on the second section of the new US 34 bridge over I-25. After rescheduling multiple times due to weather, crews will pour the new concrete deck on the new portion of the US 34 bridge during nighttime hours on March 22.

When complete, the new US 34 bridge will add an additional through lane in each direction, reconfigure the on- and off-ramps, and improve pedestrian access. The project will also increase capacity on I-25 by adding an Express Lane in both directions, constructing inside and outside shoulders, and replacing aging bridges. The project will also improve multimodal access to regional transit.
