Sioux Falls, SD

AARP Community Challenge Grant Year: 2019

Project Category: Roadway/sidewalks/crosswalk improvement

Description: This demonstration project had the goal of calming traffic and improving the streetscape for pedestrians. Downtown Sioux Falls used paint to create temporary bumpouts -- or curb extensions -- at a local crosswalk, which shortened the distance pedestrians spent in the street. They also used large planters to create a physical barrier between pedestrians and cars and added reflective delineators to make crosswalks more visible at night. A camera installed onsite helped capture data about traffic and pedestrian behavior during the pop-up project. The result: Drivers actually slowed down said Joe Batcheller, the organization's president. The project helped reduce speeds by 20 percent on average. Project organizers say the demonstration sparked a cultural shift around pedestrian safety. Since the pop-up, the City has painted curb bumpouts in other locations.

Anchorage, AK

AARP Community Challenge Grant Year: 2019

Project Category: Roadway/sidewalks/crosswalk improvement

Description: Organizers with Bike Anchorage wanted to give neighbors a glimpse at what their streets could look like with tweaks to make them safer and more pedestrian-friendly. They equipped a trailer with cones, spray chalk, signage and other traffic calming supplies, ready to deploy to locations ripe for pop-up demonstrations. In one such demonstration at a busy intersection near the public library, volunteers installed a temporary roundabout which successfully calmed vehicle traffic. They also created a temporary protected bike lane downtown. The project has already inspired more permanent improvements -- officials have earmarked funds for a future roundabout at the site near the library.

Des Moines, IA

AARP Community Challenge Grant Year: 2024

Project Category: Roadway/sidewalks/crosswalk improvement

Description: Des Moines' first Complete Streets design boosted walking and biking along Ingersoll Avenue, but busy driveways posed safety risks, especially for older adults more vulnerable in collisions. To address this, the district installed 40 "Watch for Pedestrians & Cyclists" signs at many local properties, creating a consistent safety message across the corridor. With pedestrian visits topping 2 million annually and bike traffic doubling, the permanent signage strengthens long-term safety and complements the city's vision. "We want to encourage this as much as we can and keep our residents safe," said one property owner, underscoring community support.
