Stop me if you’ve heard this before: It was another week of carnage for people walking, biking, and driving around the city.

Between September 17 and September 23, motorists inflicted life-changing injuries on four people walking, one person biking, five people on motorcycles, and eight people in cars, according to the Denver Police Department.

One person, Juan Bustamante, was killed in a collision involving two automobiles near the intersection of I-70 and Holly Street.

With this series, we aim to remind politicians, transportation officials, local media, and the public that the cost of inaction on traffic safety policies is extremely high. The longer it takes to redesign our car-centric streets, the more people will get hurt or killed.

The Hancock administration and Denver PD still lack a protocol for alerting the public to serious traffic collisions and tallying them accurately, despite the mayor’s ostensible commitment ending traffic deaths, announced more than two years ago. Hopefully documenting this information, gathered from Denver PD reports, will help drive change from decision-makers and elevate the profile of this public health crisis.
