The League of American Bicyclists upgraded Iowa Citys bicycle-friendly status from bronze to silver on the first day of Bike to Work Week.

The national organization reviews a city’s Bicycle-Friendly Community status every four years, according to a city press release. Some of the city’s recent efforts include implementing sharrows and bike lanes on heavily traveled streets, installing additional bike racks downtown and near the University of Iowa campus, and establishing a permit system for on-street parking for mopeds and scooters, the release said.

Signs displaying the city’s bicycle-friendly designation will be upgraded to reflect the change.
