Getting around Colorado can be a breeze if you know which toll pass to use. The most versatile option for Colorado is the ExpressToll Pass, which works on all state toll roads and offers discounted rates. Whether you’re a daily commuter or just passing through, having the right toll pass can save you both time and money. Keep reading to discover the best pass for your needs and how to get it.

Colorado’s Major Toll Roads

Colorado’s toll roads offer several routes to help you avoid traffic and save time. Each road has unique features and payment systems that you should know about before you hit the road.


E-470 is one of the main toll roads in Colorado, running along the eastern perimeter of the Denver metropolitan area. This 47-mile road starts at I-25 in the north and connects to the same interstate in the south, passing through areas like Aurora and Centennial.

This toll road is entirely electronic. You will need an ExpressToll account or a Go-Pass to pay the tolls. There are no physical toll booths, which helps in maintaining traffic flow. The road also offers toll discounts for regular commuters.

Northwest Parkway

The Northwest Parkway is a 9-mile toll road connecting E-470 at I-25 with U.S. 36 in Broomfield. This route is essential for those traveling between the northern suburbs and Boulder, as it avoids congestion commonly seen on alternative routes.

Similar to E-470, this parkway uses all-electronic toll collection. You will require an ExpressToll account or a Go-Pass to travel on this road. It’s worth noting that the Northwest Parkway has fewer exits and entrances, making it a faster but more limited option.


C-470 is a free highway that has express toll lanes. These toll lanes were added to manage congestion and provide a quicker travel option between I-25 and Wadsworth Boulevard. The toll lanes stretch for about 12.5 miles and are a good choice during peak hours.

You can use ExpressToll to pay for the lanes. Unlike other roads, C-470 offers both free and toll options, giving you the flexibility to choose based on your needs.

I-70 Mountain Express Lanes

The I-70 Mountain Express Lanes are designed to ease traffic congestion in the mountainous regions, particularly between Empire and Idaho Springs. These lanes are open only during peak travel times, and their use is optional.

An ExpressToll pass is essential for these lanes. The Mountain Express Lanes are ideal if you want to skip heavy traffic on I-70, especially during weekends and holidays when traffic can be particularly challenging.

Using toll roads in Colorado can save you a lot of time, especially during peak travel periods. Each road offers unique benefits, making them valuable options for reducing travel times and avoiding congestion.

Types of Toll Passes

In Colorado, you have several options for toll passes that work on all toll roads, including Express Lanes, E-470, and the Northwest Parkway. Below, you’ll find the different types of passes explained in more detail to help you choose the right one for your needs.

ExpressToll Pass and Sticker Pass

The ExpressToll Pass is the most common type of toll pass in Colorado. It works on all Colorado toll roads and provides the added benefit of discounted toll rates. This pass can be mounted to your vehicle’s windshield, making it easy to use.

The Sticker Pass, which is a type of ExpressToll Pass, is smaller and more discreet. It also attaches to your windshield and offers similar discounts. Both passes require an ExpressToll account, which you can manage online.

License Plate Toll

The License Plate Toll (LPT) is a good option if you don’t want to bother with a physical pass. Cameras on the toll roads will take a picture of your license plate, and you will receive a bill in the mail. While convenient, this method is usually more expensive than using an ExpressToll Pass or Sticker Pass.

If you’re renting a car, some rental agencies might automatically enroll you in their toll programs, adding extra fees. Always check with the rental company to avoid unexpected charges.

Switchable HOV3+ Transponder

The Switchable HOV3+ Transponder is unique because it allows you to switch between toll-paying and carpool (HOV3+) modes. HOV3+ means that you have three or more people in your vehicle, which can allow you to use the express lanes for free.

This transponder must also be mounted to your windshield. Before using the express lanes, you switch the transponder to the carpool option to avoid tolls when you have enough passengers. Make sure your ExpressToll account is updated to reflect this pass.

Registration and Account Management

In Colorado, managing toll payments involves setting up and keeping track of accounts, such as ExpressToll and License Plate Toll accounts. Each type of account has its own procedures and benefits.

Creating an ExpressToll Account

Setting up an ExpressToll account is straightforward. Begin by visiting the ExpressToll website to register. You’ll need to provide your vehicle details and a credit card for payment.

Upon registration, you are required to make an initial deposit of $35, which goes into your prepaid account balance. This deposit is used to pay future tolls automatically.

Once registered, you’ll receive a windshield-mounted transponder to install in your vehicle. This device ensures seamless toll payments when driving through Express Lanes, including on highways like I-25 and C-470.

Maintaining Your ExpressToll Account

After creating an ExpressToll account, managing it is simple. You can access your account online to check your balance, view transactions, and update your vehicle details or credit card information.

You should regularly check your prepaid account balance to ensure it has enough funds to cover tolls. The system will automatically replenish your account using your credit card when the balance falls below a certain level, ensuring you never miss a payment.

Additionally, you can view statements and set up email notifications for important updates. This helps you stay informed about your account activities and any necessary actions, like updating expired credit card information.

License Plate Toll Account

If you don’t have an ExpressToll account, you are automatically enrolled in the License Plate Toll system when you use toll roads. This system captures an image of your license plate and sends a bill to the vehicle owner’s registered address.

The payment process is different as it bills you after the toll usage rather than deducting from a prepaid balance.

To manage this account, visit the E-470 website where you can view your bill and make payments online.

Keep your vehicle registration address up to date to ensure you receive the toll statements promptly, avoiding late fees and penalties. This system offers a convenient alternative for those who do not travel toll roads frequently enough to warrant an ExpressToll account.

Payment Methods and Tolls

When traveling on Colorado toll roads, it’s important to understand the different payment methods and how tolls are calculated. This helps in planning your travel expenses and ensuring a smooth journey.

Toll Rates and Discounts

Toll rates in Colorado vary based on the road, time of day, and your vehicle type. For instance, driving on E-470 can cost anywhere from $0.50 to $5.00. Some roads, like the Northwest Parkway, have fixed rates while others, like certain lanes on Interstate 25, use variable pricing. Carpool lanes often offer discounted rates or even free passage if you have an HOV (High-Occupancy Vehicle) transponder, such as the Switchable HOV3+ Transponder from ExpressToll.

Managing Payment Methods

You can manage your toll payments through various methods. The ExpressToll and Go Pass systems allow you to prepay tolls. You can set up an account online, prepay an amount like $35, and receive a toll transponder to place in your car. Payment can be done using credit cards, debit cards, or even prepaid accounts.

Understanding the Tolling Process

In Colorado, tolls are collected electronically, making travel smoother and more efficient. Knowing where tolling points are and how they are enforced helps ensure you can travel with ease.

All-Electronic Tolling System

Colorado uses an all-electronic tolling system, which means there are no toll booths and no need to stop your car. Tolls are either charged through an ExpressToll account or billed by mail using license plate recognition.

Setting up an ExpressToll Account involves prepaying $35 in tolls and getting a transponder for your car, as explained by the Colorado Department of Transportation.

ExpressToll transponders are stickers placed inside your vehicle. The system reads the transponder as you drive, automatically deducting the toll amount. This seamless process saves time and reduces traffic congestion.

Tolling Points and Enforcement

Tolling points in Colorado include mainline toll locations and ramp tolls. One such example is the Northwest Parkway which connects E-470 at I-25 with U.S. 36 in Broomfield.

If you don’t have an ExpressToll account, cameras will capture your license plate number. You will then receive a bill through the mail. This method ensures every vehicle is accounted for and tolls are collected efficiently.

Choosing the right toll pass and understanding how tolling points work will help you drive without interruptions. Always ensure your transponder is correctly placed and your account is up-to-date to avoid potential penalties and late fees.

Additional Considerations

When choosing a toll pass in Colorado, there are several key factors to keep in mind. From carpooling benefits to using rental cars and ensuring compatibility with other passes, these details can make a big difference in your travel experience.

Express Lanes and Carpool Options

Colorado has Express Lanes that offer quicker travel times. If you carpool, you can use the Switchable HOV3+ Transponder. This pass is unique because it has a switch that lets you indicate if you have a high number of passengers. When switched to HOV mode, you can avoid toll fees.

Keep in mind, only vehicles with at least three people in them can use the HOV mode. This means if you often travel with friends or family, this pass can save you money.

Motorcycle and Rental Car Tolling

If you ride a motorcycle, you’ll also need a toll pass if you want to use Express Lanes. Motorcycles are not automatically exempt from toll fees in these lanes. Consider getting an ExpressToll account for easier payments.

For rental cars, many agencies equip vehicles with non-removeable toll transponders. You’ll automatically be opted into the rental agency’s toll plan, and extra fees may apply. To avoid surprises, ask the rental agency about their toll policies.
