The I-25 Toll Nobody Priced Into a Northern Colorado Commute

For eight years, the extra lane threaded through Berthoud, Johnstown, Loveland and Timnath was free to use once you learned where the merge points were. On April 7, 2026, that changed. The Colorado Department of Transportation began charging for the Express Lane on the 14-mile stretch of I-25 between Colorado 56 in Berthoud and a point just past Prospect Road in Fort Collins, and the price isn't fixed. It moves with the clock and with the direction you're driving, which means two homes that look identical on a listing sheet can carry very different commute costs depending on which side of the highway they sit on.
That's the part buyers comparing Timnath, Loveland, Johnstown and Berthoud against a job in Denver or Boulder haven't priced in yet. The median price gap between these towns gets plenty of attention. What the toll actually does to the math behind "close to I-25" hasn't.
The tolled stretch adds one Express Lane in each direction alongside the two general-purpose lanes that were already there, so nobody loses a free lane, they gain a paid option next to it. According to CDOT's own rate announcement, drivers with an ExpressToll transponder pay between $1.00 and $4.75 per segment, with the exact number depending on the segment, the direction, and the time of day. CDOT's published example is the clearest way to see the range in action: a driver using all three segments from 11 p.m. to 6 a.m., when rates sit at their floor, pays a minimum of $3 for the full 14 miles. A driver making the same trip northbound between 6 and 7 p.m., the top of the evening peak, pays as much as $12.20.
Motorcycles ride free. So do buses and vehicles carrying three or more people with a switchable HOV transponder set correctly. Everyone else pays, and CDOT is now backing that up with cameras. A 30-day warning period for weaving over the solid Express Lane lines ran through May 6, 2026. Since May 7, the fine for crossing those lines is $75, enforced automatically without an officer present.
What makes this a real estate story instead of a traffic story is the asymmetry. A flat toll would just be a fixed cost, easy to fold into a monthly budget the same way you'd fold in a parking fee. This one isn't flat. The $3 floor and the $12.20 ceiling aren't outliers, they're the two ends of a pricing system that resets by segment, by direction, and by hour, every single day.
That means the toll cost of a commute depends less on how many miles you drive and more on which way you're driving them when the price is high. A household in Timnath commuting south into Denver hits the corridor at the exact hours CDOT prices highest. A household in the same town working a shift that runs the opposite direction, or commuting north into Fort Collins for a job with Poudre Valley Health System or Colorado State University, is paying a different number for the identical stretch of road. Neither driver is doing anything wrong. They're just on opposite sides of a pricing curve that a listing price per square foot has no way of showing.
The corridor CDOT tolled runs from Colorado 56 in Berthoud on the south end to just past Prospect Road in Fort Collins on the north end. Segment records from the build-out show the middle boundary sitting at Colorado 402 in Johnstown, with the Fort Collins side extending down from Mulberry Street. Read on a map, that means Berthoud, Johnstown, Loveland and Timnath all sit inside the tolled stretch. A commute that starts in any of those towns and uses the Express Lane for even part of the trip is now a metered decision, made twice a day, five days a week.
Wellington sits north of Prospect Road, outside the tolled segment entirely. A Wellington household commuting into Fort Collins never touches this toll on that leg of the trip. The same household would start paying only if their commute continued south past Fort Collins into the tolled zone, which is a different calculation than someone starting their day already inside it.
None of this changes what a house is worth on paper. It changes what living in it costs once you count the toll as a recurring line item rather than a one-time curiosity.
The tolled 14 miles only cover part of the trip to Denver. South of Berthoud, the corridor still narrows to two lanes each direction on the stretch between Mead and Berthoud, a project CDOT says won't finish until 2028. Until that gap closes, paying the toll buys speed through the widened section, not a fully free-flowing drive the whole way to the metro area. A buyer weighing Berthoud specifically, sitting right at the southern edge of the newly tolled zone, is choosing a town where the toll exists but the congestion problem it was built to solve isn't fully solved yet.
When the Mead-to-Berthoud segment does open, CDOT says it will mark the first time three lanes run continuously on I-25 in both directions all the way from Denver to Fort Collins. That's also the point at which the pricing structure described here likely extends further south, changing the math again for towns like Mead and Berthoud that currently sit at the project's edge rather than its middle.
None of this is an argument against any particular town. It's an argument for reading the toll the same way you'd read a metro district mill levy or an HOA fee, as a recurring cost tied to where the house sits rather than to the house itself. A buyer commuting daily through the tolled zone at peak hours is signing up for a cost that a similar home in Wellington, or a home whose owner works a schedule that avoids the pricing curve, simply doesn't carry.
The corridor's own history is a reminder that this isn't a surprise CDOT sprang on the region. Fort Collins, Loveland, Berthoud, Johnstown, Timnath and Windsor were named local partners on the project from early on, alongside Larimer and Weld counties, which means the toll funds a road these same communities asked to have built. That doesn't make the daily charge disappear. It just means the question worth asking before an offer isn't whether the toll exists, it's how often a specific commute pattern will actually hit it.
Is there a way to use the Express Lane without paying? Yes, but it requires meeting a specific condition. Vehicles with three or more people and a switchable HOV transponder set to HOV mode ride free, as do motorcycles and transit vehicles. Anyone driving alone or with one passenger pays the posted rate through either an ExpressToll account or a License Plate Toll.
Do the general-purpose lanes still exist for free? Yes. The toll only applies to the new Express Lane. The two general-purpose lanes that existed before April 2026 are still there and still untolled, they're just not the lane getting priced by time of day.
Will the price structure change again this year? CDOT and the Colorado Transportation Investment Office have indicated this corridor is moving toward real-time dynamic pricing, a shift away from the current time-of-day schedule and toward rates that respond to traffic conditions as they happen. Anyone budgeting a specific commute cost around today's numbers should treat them as a snapshot, not a fixed rate.
