Key Findings of the Study

• The $2.25 Billion Annual Economic Toll: The report calculates that congestion, delays, and corridor closures cost Colorado’s economy approximately $2.25 billion each year. This marks an increase from $839 million in a comparable 2005 baseline study, representing a 53% real increase even after adjusting for inflation.

• Productivity & GDP Losses: The largest share of the financial hitan estimated $1.9 billionstems from lost worker productivity and reduced business efficiency across approximately 2 million regional employees affected by long transit delays and commute unpredictability.

• Tourism and Recreation Vulnerability: Unreliable travel times actively deter recreational trips, ski visits, and mountain tourism. The study notes that just a 1% decline in mountain resort tourism spending puts roughly $47 million in annual resort revenue and over $2 million in local and state sales tax revenue at immediate risk.

• Freight and Supply Chain Strain: Freight carriers logged more than 159,000 truck delay hours along the corridor in 2024, adding upwards of $14 million in annual shipping and detour expenses statewide. Mountain communities bear acute consequences through delayed deliveries, inventory volatility, and increased retail prices.

• Cost of Inaction: The study emphasizes that delaying structural fixes compounds the expense. Estimated corridor capital improvement costs have escalated to roughly $30 billion, while annual highway maintenance alone exceeds $44 million.

The study frames the I-70 bottleneck not simply as a commuter nuisance, but as a major structural limit on Colorado’s statewide economic growth, serving as leverage for regional policymakers pushing for transit alternatives, safety investments, and multimodal rail initiatives.
