As of April 7, 2026, a familiar stretch of I-25 in Northern Colorado is operating a little differently.
The new I-25 Express Lane Tolls between Berthoud and Fort Collins are now tolled, introducing dynamic pricing designed to keep traffic moving, especially during peak travel times.
Spanning approximately 14 miles, this section of I-25 is part of a broader effort to reduce congestion and improve travel reliability along the corridor.
How the I-25 Express Lane Tolls Work
The system uses adjustable toll pricing, meaning:
- Prices change based on real-time traffic conditions
- Tolls are typically higher during peak travel times
- Rates decrease when traffic is lighter
Overhead signs display current toll rates before you enter, helping drivers decide whether to use the lane.
The goal is to maintain a steady flow of traffic in the express lanes, even when the general lanes slow down.
How to Use the Express Lanes
There are a few different ways drivers can use the Express Lanes, depending on their vehicle and number of passengers:
Tolled Vehicles (1–2 People)
Vehicles with one or two people can use the Express Lanes by paying a toll through an ExpressToll account or via License Plate Toll.
HOV3+ (Free with Requirements)
Users must have an ExpressToll account, a Switchable HOV transponder set to “HOV” mode, and three or more people in the vehicle to use the Express Lanes for free.
Motorcycles (Free)
Motorcycles can use the Express Lanes at no cost, with no pass required.
Buses & Transit
Buses and other transit vehicles are also permitted to travel in the Express Lanes.
Understanding which category you fall into can help you avoid unexpected charges and use the lanes correctly.

What This Means for Colorado Drivers
If you travel this stretch of I-25 regularly, here are a few things to keep in mind:
- Using the express lanes is optional
- Toll rates vary depending on time of day and traffic
- Pricing is clearly displayed before entry
For some drivers, the express lanes may offer a faster, more predictable commute. For others, the general lanes remain a no-cost option.
Adjusting to New Traffic Patterns
Any time a new system is introduced on a major roadway, there’s an adjustment period.
Drivers may be:
- Merging more frequently
- Slowing down to check toll pricing
- Making last-minute decisions about entering or exiting lanes
These changes can increase confusion and in some cases, the risk of accidents, especially when drivers are distracted.
April Is a Reminder to Stay Focused Behind the Wheel
April is Distracted Driving Awareness Month, a national campaign led by the National Highway Traffic Safety Administration to highlight the risks of distracted driving.
In fact, distracted driving continues to be a serious issue nationwide, contributing to thousands of deaths and injuries each year.
This matters even more as drivers adjust to new traffic patterns on roads like I-25.
When your attention shifts (even briefly) it becomes harder to react to what’s happening around you. That includes not just other vehicles, but also motorcyclists and pedestrians, who are more vulnerable and easier to miss.
As the weather warms up in Colorado:
- More motorcycles are back on the road
- More pedestrians and cyclists are out and active
A few simple reminders:
- Check blind spots carefully, especially for motorcycles
- Watch for pedestrians at intersections and crossings
- Put your phone away and avoid using it until you get to your destination.
- Stay alert when merging or changing lanes
Staying Safe on the Road
As traffic patterns shift, a few simple habits can help reduce risk:
- Signal early when changing lanes
- Avoid sudden stops or last-minute merges
- Keep a safe following distance
- Stay focused and limit distractions
Small adjustments can go a long way in keeping yourself and others safe.
When a Routine Drive Doesn’t Go as Planned
Even with the best intentions, accidents can still happen, especially during periods of change when not every driver is fully adjusted to new traffic patterns.
