You will be fined for crossing the solid white line on these Colorado roadways

DENVER (KDVR) — Soon, more roadways will have technology that catches and fines drivers who cross the solid line in express lanes.

About a year ago, the Colorado Department of Transportation started setting up cameras and sensors that track drivers weaving in and out of the solid white lines on express lanes. If caught, the penalties range from $75 if paid within 20 days, with the fine increasing to $150 after.

The technology started on the Interstate 70 Mountain Express Lane corridor and expanded to Interstate 25 and C-470 corridors. During the beginning of the crackdown, the technology tracked 40,000 drivers violating the rule in just 20 days. After the first nine months, the department said it issued over $40 million in fines for I-25 toll violations.

Only a few roadways had this technology. Now, there's going to be more.

More technology installed to catch express lane violations

Starting Dec. 1, the department said the new technology will be in place on Central 70, I-25 South Gap and U.S. 36 corridors -- and drivers will soon face fines.

According to CDOT, drivers who enter or exit the express lanes outside the designated areas will receive a warning during the 30-day grace period. Those warnings will be mailed to the registered address of the vehicle.

Starting on Jan. 1, 2025, the warning period will end and violators will receive fines starting at $75.

By December, the department said the remainder of the state's actively tolled express lanes will have the new technology, which includes I-70 between I-25 and Chambers Road, I-25 between Monument and Castle Rock, and U.S. 36 between Federal Boulevard and Table Mesa Drive.
