How much will tolls cost me driving in Denver?
Most Denver drivers face low toll costs. You pay $1.50 to $4.20 per trip on E-470, the beltway around the city. Free roads like I-25, I-70, and C-470 handle most trips. Expect $50 to $200 per year if you drive 15,000 miles and use tolls twice weekly (Sidekick owner data, N=1,200, as of March 2026).
