Open traffic signs visible in Boulder, police investigating

DENVER (KDVR) — Boulder police launched an investigation Tuesday after four signs with explicit messages were found affixed to speed limit signs in the city.

Signs found in:

• Table Mesa Drive and South Broadway

• 28th Street and Palo Parkway

• 28th Street and Cross Highway

28th Street, also known as the North Foothills Highway, is also Highway 36 and represents where the highway became a local road through Boulder. It is an important thoroughfare for motorists, as is the Diagonal Highway.

The signs used clear language telling drivers to “slow down (expletive),” put down the phone (expletive) and “don’t kill any kids today.” The fourth sign listed the speed limit as “slow down (expletive).”

according to City of Boulder crash data interactive map toolThere were three fatal crashes in Boulder in 2023, but none of them occurred near where the signs were installed. But a Woman killed on Broadway near Raleigh Road after he was hit by a car just before 5 a.m. on Sept. 27.

The other 55 accidents resulted in injury. Five of these crashes occurred on 28th Street in Boulder. The city focused on reducing crashes on roadways through its 2023-2027 Vision Zero Action Plan and implemented a citywide default speed limit of 20 mph.

The Boulder Police Department told FOX31 that as of Tuesday evening, the city’s Department of Transportation and Mobility was in the process of removing the four signs identified.

It’s unclear if there are other signs or who placed the signs around the city. Boulder police are investigating signs of criminal tampering and ask anyone with information to call the Boulder police department’s non-emergency line at 303-441-3333 and the reference line at 24-12182.
