FAQs
General Information
What’s the difference between Northwest Parkway and E-470?
The Northwest Parkway and E-470 are two entirely separate toll roads, joined together at I-25, north of Denver. Both Northwest Parkway and E-470 use the ExpressToll® prepaid pass system. The same ExpressToll® tags may be used on Northwest Parkway and on E-470, as well as all HOV Lanes in Colorado. If, however, you do not have an ExpressToll® account and you receive a GO-PASS™ bill from Northwest Parkway and a License Plate Toll bill from E470 for your tolls, you must pay each of these bills separately. E-470 is the toll road that circles the eastern metro Denver area and extends from I-25 in the south at approximately Lincoln Avenue to I-25 in the north between 144th Avenue and State Highway 7. Northwest Parkway extends from E-470 at I-25 in the north to Highway 36 (the Boulder Turnpike).
Where can I get on the Northwest Parkway?
While traveling north/west on E-470, after crossing under the I-25 bridge
From I-25, take Exit 228 toward Broomfield
From US 36, take the Interlocken Loop exit and head north
Sheridan Pwky (just east of Lowell Blvd) going west or east
Dillion Rd (directly off HWY 287) going west or east
Why should I have to pay tolls to drive on your road when I pay my taxes?
Northwest Parkway is a fully privately funded road open for public use, should motorists choose to use this toll road. No federal or state tax dollars went into building the road, or goes into operating, maintaining and improving the road. These costs are paid exclusively by the users of the Parkway from the tolls collected
Are bicycles allowed on the Northwest Parkway?
What is the speed limit?
The speed limit on most of our main road is 75 mph. However, on the west end of Northwest Parkway, westbound traffic is to reduce their speed to 45 mph before approaching the 96th Street intersection. This is the one and only traffic signal on the main road of the Parkway where it begins the urban area and slower speeds are required for safety. On the entrance and exit ramps to the toll road, where there are tolling locations, the speed limit is 35 mph. All ramps have posted speed limits.
Are motorcycles allowed on the Northwest Parkway?
Yes. ExpressToll® customers who have motorcycles should add their motorcycles to their accounts. Unless the motorcycle is listed and receives its own tag, the customer’s ExpressToll® affiliation will not be recognized, and the customer will receive a GO-PASS™ bill from Northwest Parkway for the toll(s), plus any applicable fees.
Customers of the road who do not have an ExpressToll® account are also welcomed to drive their motorcycles on Northwest Parkway. Motorcycles are treated as any other 2 axle vehicle.
How do I contact the Northwest Parkway?
Please click here for all of our contact information and hours.
Can I use the “emergency turnarounds” on the toll road?
No. All the turnarounds are signed as “EMERGENCY and AUTHORIZED VEHICLES ONLY”. If you are not one of these two types of drivers, you are not allowed to use these turnarounds and will be treated as a traffic offense subject to a fine. It is extremely dangerous for other drivers to use these turnarounds, and their use is strictly prohibited.

What if I get on the toll road by mistake? Do I still have to pay the tolls?
Yes. Everyone who travels on the Northwest Parkway must pay the tolls that are due. Signage is installed in advance of entering the tollway to indicate to drivers that they are approaching or about to enter a toll road. There are opportunities after the signage to avoid taking the toll road. If, however, you miss seeing the signs and end up on the toll road by mistake, you are required to pay the tolls and any other applicable fees.

As I drove through the tolling area I saw a flash. I think a picture was taken of my vehicle. Is that a problem?
Why have the toll roads in Colorado (Northwest Parkway and E470) closed their tollbooths and gone to non-stop tolling?
Non-stop tolling is safer, more environmentally friendly and convenient. With non-stop tolling you don’t need to slow down in order to pay at the toll booth, and then accelerate again to merge back into traffic. This not only helps avoid accidents, but it also saves you time and helps your fuel economy by maintaining a consistent speed.
ExpressToll® Account Info
Can I move my ExpressToll® tag from vehicle to vehicle?
No. An ExpressToll® tag is assigned to a specific vehicle/license plate number (LPN). If, for any reason, a tag fails to read properly when going through a toll collection point, the back-up is the vehicle LPN. Our system will take a picture of the LPN and then search through the database to find a match listed on an active ExpressToll® account. If no match for the LPN is found, the system classifies the transaction as a GO-PASS™ transaction and a GO-PASS™ bill will be created for the toll and fees may also apply. Therefore, customers should obtain a tag for each vehicle that they will drive on the toll road. There is no charge for receiving additional tags. All tags listed on an account will draw from the same account balance. You can order your tags online at www.expresstoll.com.
I am an ExpressToll® customer. I sold my car and purchased a new vehicle. Do I need to report the change of vehicles?
Yes. It is important that you keep your ExpressToll® account updated with current vehicle/license plate information. If your account is not updated, you will receive a separate GO-PASS™ bill for your Northwest Parkway transactions. You may update your account by calling ExpressToll® Customer Service at 303-537-3470, or you may update the account through the website, at www.expresstoll.com.
I am an ExpressToll® customer, but I just got a GO-PASS Bill in the mail from Northwest Parkway. Why?
The Northwest Parkway accepts ExpressToll® passes as payment for our tolls. If, however, you received a separate bill from us, that could indicate something does not match up with the ExpressToll® account. Potential causes can be the license plate number is not listed on your account, the license plate number was added to the account after the time the toll occurred or the credit card used for your ExpressToll® account has expired. Just give us a call at 303-926-2500 so we can help determine the reason to avoid receiving separate bills from Northwest Parkway in the future.
Why can’t you run the tolls that I was billed for on the GO-PASS Bill through my ExpressToll® account?

We are committed to offsetting our carbon footprint and moving closer to a future of sustainable and responsible mobility.
Environment
We are proud to feature nine solar panel sites along the Northwest Parkway.
The most recent panels were installed in April 2025 at our administrative building and maintenance facility, the latter of which now produces over 100% of its electricity needs from solar energy. The Parkway's nine solar sites collectively produce 150kw of energy and have reduced our emissions by an equivalent of 900 tons of CO2 since 2011.
We are grateful to the Northwest Parkway Public Highway Authority for their support in this green energy initiative. The project reflects VINCI Highways' efforts toward environmentally-focused mobility operations and net-zero ambitions, as well as our dedication to the Parkway's beautiful natural surroundings

Parkway operations.
The Northwest Parkway is proud to utilize environmentally-friendly granulate to salt its highway pavement in snowy weather.
Simple rock salt - aka sodium chloride - is commonly applied by road maintenance crews to melt down snow and ice. Sand can also be used to provide vehicle traction. But both can have damaging effects on property, infrastructure, and the environment by causing pavement corrosion, contaminating water supplies, and endangering plants and wildlife (who like licking the salt).
When it snows at the Northwest Parkway LLC, our road is treated with a naturally-occurring granulate from neighboring Utah. The product's mineral granules contain corrosion inhibitors, making it more effective at melting snow and ice than salt sprayed on the road surface. In addition, the product's dark color quickens the melting process by absorbing 50% more of the sun's energy and melting down to 5°F - seventeen degrees lower than road salt. Consequently, the road requires fewer applications and less product is used, which results in less of it introduced to the environment.
The Northwest Parkway takes pride in its beautiful natural surroundings. For this reason we are committed to environmental preservation by constantly working to reduce our impacts and optimize our operations.
Fun fact: our granulate is called "Ice Slicer" and delivers enhanced road traction, eliminating the need for sand and any resulting sediment and cleanup!

Our local owls have made their home in our maintenance shed for the past few years. They have built their nest in the building's upper roof beams, and this interior location provides them with safety and comfort during their nesting season. While local owls usually prefer tall cottonwood trees with many branches, the best way to support them in our environment is to allow them to nest in safety. We expect their eggs to hatch in the coming months!
Other avian species living along the Parkway include doves and falcons, whom you can see sitting on light poles or in the sky as they hunt for mice and snakes.
The Northwest Parkway consults with the Birds of Prey Foundation (BoPF) located just down our highway in Broomfield, Colorado. In the event we do find an injured bird around our facilities, we also bring it to BoPF for rehabilitation.

Maintenance Operations
Our operations team works to fill the cracks in the Parkway's pavement every autumn. This seasonal program involves placing adhesive sealant inside cracks in the road's asphalt or concrete in order to prevent water infiltration. Cracks are first cleaned before the sealant is poured and leveled off, leaving a wide band of black material on the road surface. The cooler weather makes cracks wider, allowing more sealant to be placed inside it.
Regular maintenance programs like these ensure that the Northwest Parkway remains in high-quality condition with minimal disruption to drivers. Approximately 75% of roadway cracks develop into potholes within three years if not sealed. In addition, the pavement will perform longer if cracks remain sealed, which further minimizes traffic disruptions by extending the time between major pavement repairs.
As an added benefit, crack-sealed roads can also be opened to traffic almost immediately!
Crack sealing ensures
road durability.
Every winter, the Northwest Parkway mobilizes its maintenance teams with ample materials to prepare and maintain the highway in cold and snowy weather.
Five GPS-monitored plow trucks are contracted to be on site throughout the season. These trucks apply de-icing liquid and granular material to the highway pavement, ensuring safe surface conditions and steady traffic flow for drivers. During a storm, our maintenance crews work in 12-hour shifts. One truck on every shift is always operated by a supervisor who can direct the team's operations as the weather changes. The Parkway's electronic message signs are also active before, during, and after weather events to advise drivers of conditions.
Safety is our priority at the Northwest Parkway. Seasonal initiatives and strong preparation help us to create a safe road and safe conditions for our passengers.
