Colorado must refund more than $1.1 million in speeding tickets issued along a three-mile stretch of Interstate 25 outside Pueblo. The tickets were issued by automated cameras set up to catch speeders in a construction zone stretching from Indiana Avenue north to 13th Street.

All 27,000 tickets are being invalidated because the legal description of the work zone was never updated as the mobile speed cameras moved along the freeway with the construction. Speed limits were properly marked and drivers were exceeding those limits when ticketed, but the mismatch between violation locations and filed paperwork describing the work zone locations renders all tickets void.

State officials said violators can discard their violation notices. Those who already paid will receive refunds by mail without taking further action.

Colorado officials plan to reactivate the work zone cameras once the paperwork is corrected.
