Milwaukee is installing bus boarding islands along Highland Blvd to improve traffic safety and provide a protective barrier for cyclists. The city engineer explains that the islands are designed to slow down speeding vehicles and make it easier for buses to pick up riders. However, some residents have concerns about the design, claiming it makes it difficult to cross the street and is ineffective at slowing down traffic. The city plans to install more of these islands and other traffic calming measures across the city, including protected bike lanes.
