Several major road closures are impacting drivers across the United States this weekend. In Seattle, state Route 520 and sections of Interstate 405 in Renton will be closed for maintenance and upgrades, including testing new lighting and fire suppression systems. Indianapolis is planning pedestrian-friendly improvements to Georgia Street and nearby areas using $50 million in tax increment financing bonds, part of Mayor Joe Hogsett's 2025 budget plan. Police activity has led to closures on Interstate 70 westbound in Independence, Missouri, and Route 51 in Pittsburgh, Pennsylvania, causing significant traffic diversions. Additionally, police are responding to a crisis situation on Interstate 405 in Portland, Oregon, resulting in the temporary closure of northbound lanes.
