I-70 & Harlan Street Bridge Replacement & Interchange Safety Improvements

Cost: $18.6 Million

Contractor: ACC Built

Timeline: August 2022 to August 2024


Description:  This project will replace the I-70 bridge over Harlan Street which was originally built in 1967. With close proximity to Interstate 76, US 287 (Federal Boulevard) and CO 121 (Wadsworth Boulevard), this bridge experiences the highest daily traffic volumes in this corridor. Due to its age, heavy usage, and the seasonal weather, this bridge experiences frequent deck and concrete cracking. 


As a part of this project, additional safety improvements will be made to the Harlan Street, 48th Avenue, and westbound I-70 ramp intersection. These improvements were determined during a traffic study CDOT completed in 2021. This traffic study was a continuation from a 2015 safety study completed by CDOT, which identified the north intersection of the North Harlan Street and I-70 interchange as a safety concern location. This location experienced a higher-than-expected incidence of crashes during the study period of 2009 and 2014. The prevailing crash pattern and type was broadside crashes, which are statistically a more severe type of crash. Engineering improvements to the intersection can help reduce the number of crashes, specifically broadside crashes.
