to Northwest Parkway

The Northwest Parkway is a 75 mile-per-hour toll road. It is a public road and part of the Colorado highway system, connecting E-470 at I-25 in the north metro Denver area, with U.S. 36 in Broomfield, Colorado. A toll transaction is recorded on the Northwest Parkway either by reading your vehicle license plate or ExpressToll transponder, when you drive through one of our three toll locations (Mainline Plaza, Sheridan, or U.S.287 ramp) depending on the User's route. Each trip on the NWP will generate at least one toll-transaction. Check our MAPS HERE.

The Northwest Parkway is an All-Electronic Toll Road meaning you will not stop to pay your tolls at the time of travel, thus increasing convenience and safety.

Complete information about our current toll rates and applicable fees can be found HERE.

Our billing cycle runs monthly; the time between driving the road and receiving a GO-PASS toll bill can vary, as we first validate the toll transaction(s) matching to the User vehicle's account and in case the User does not have an account (GO-PASS or ExpressToll) we need to obtain the User vehicle's information. To learn more about our GO-PASS billing process please click HERE.


Failure to pay a toll bill on time and in full is considered a breach of contract for use of the Northwest Parkway and may be subject to additional fees and legal action.
