High-Crash Corridors
I-70, I-76, and Wadsworth Boulevard
Interstate 70 runs east-west along Arvada's southern boundary as the main mountain freight corridor into the Rockies. Interstate 76 terminates at the I-70 and Wadsworth Boulevard (SH-121) interchange in Arvada, connecting to northeast Denver. Wadsworth Boulevard (Colorado State Highway 121) is a CDOT-maintained north-south state highway documented as Arvada's most dangerous road corridor by city traffic safety records, with high vehicle speeds and heavy commuter and freight traffic running the full length of the city. Colorado State Highway 72 (Ward Road) carries additional traffic through Arvada's corridor, with signals maintained by CDOT. These roads concentrate commercial truck volume and crash risk in the same stretch of city.
