Denver Gas Prices Hit $3.92: What It Means for Your Commute

Denver drivers saw average unleaded prices climb to $3.92 a gallon at stations across the metro area on July 9, a 14-cent jump from the prior week tied to reduced tanker traffic through the Strait of Hormuz.

The spike arrives just as the city finalizes its 2027 transportation budget and residents plan summer road trips on routes like Interstate 25 and Interstate 70. Local households already spend an average of $2,800 yearly on fuel according to Colorado Energy Office figures, so even modest increases quickly cut into grocery and rent money for families in neighborhoods from Five Points to Lakewood.

Commuter Routes and Neighborhood Stops Feel the Pinch

Staff at the RTD operations center near the Federal Center in Lakewood report higher ridership on the W Line and bus routes serving downtown from Aurora, as some workers switch from driving after filling up at stations along Colfax Avenue. The Denver Metro Chamber of Commerce noted that small delivery firms based in the RiNo Art District have added fuel surcharges to invoices this month, passing costs to restaurants and breweries that rely on daily shipments of ingredients and kegs.

City planners at the Denver Department of Transportation and Infrastructure are reviewing contingency options for the upcoming FasTracks expansions, including potential delays on the East Line extension that serves the Central Park and Montbello areas. Those projects depend on stable diesel prices for construction equipment and material hauls.

Budget Numbers and Practical Steps for Residents

The Colorado Department of Transportation logged a 9 percent drop in diesel sales at its I-70 mountain corridor pumps between June 25 and July 8, data released Wednesday. At the same time, the regional average for regular gasoline reached $3.92 according to the American Automobile Association’s daily survey covering 1,200 stations in the eight-county metro area.

Drivers can track real-time prices through the GasBuddy app and consider the RTD EcoPass program, which offers monthly transit access starting at $114 for unlimited rides on buses and trains. The city’s website also lists free bike-share kiosks at 22 locations, including Civic Center Park and the 16th Street Mall, as lower-cost alternatives for short downtown trips while prices remain elevated.
