How It Works

ExpressToll is an all-electronic toll collection system available on E-470, Northwest Parkway and CDOT’s Express Lanes on I-25, I-70, US36, and C-470. ExpressToll customers register their vehicle and payment information in an online account, and they receive a free, windshield-mounted transponder to install in their vehicle. When passing through a tolling point, the transponder is scanned and the toll is automatically billed from the prepaid account balance.

ExpressToll accounts can accommodate multiple vehicles within a household or business. In addition, customers save more than 35% on E-470 tolls over License Plate Toll customers.

An ExpressToll account requires an initial deposit of $35 (check or credit card accepted) in pre-paid tolls. Once you drive the road, your tolls are automatically deducted from your account. When your account balance runs below your threshold, your credit card will automatically be charged to bring your balance back up to $35.
