CDOT I-270 Critical Bridge Replacements Project

About the Project

The I-270 Critical Bridge Replacements project will rebuild eight bridges along the I-270 corridor that are deteriorating and have been in service for more than 50 years. These structures, which require frequent emergency deck repairs, are at the end of their service life and need replacement for the sake of public safety. CDOT is advancing the bridge design so reconstruction of these critical structures can begin as soon as possible.

The 7-mile-long I-270 corridor serves as an inner beltway for the Denver region, providing a direct connection between I-25 and I-70. It is a corridor of commerce, where the region’s key industry clusters of energy, advanced manufacturing, and logistics reside.

CDOT has conducted more than 300 emergency repairs on I-270 bridges since 2006, totaling over $1 million in repair costs.
