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).

• 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

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.

No. The high speeds on Northwest Parkway make it an unsafe environment for bicycles or pedestrians.

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.

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.

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.

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.

A picture is taken of every vehicle.  From the license plate number we determine the registered owner of the vehicle, as well as if the vehicle is enrolled in our GO-PASS™ Auto-Bill service, or if the plate number is listed on an active ExpressToll account.  Then, we are able to determine how the toll amount is to be processed/ billed. 

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.

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.

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.

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.

Once the separate bill has been created, it needs to be paid separately. When the bill has been paid, and the situation that resulted in the separate billing has been properly resolved, you should not continue to receive bills from Northwest Parkway. Future toll transactions will be paid through your ExpressToll account.
