History

Lloyd Expressway

Within the City of Evansville, the portion of SR 66 east of US 41 is known as the Lloyd Expressway. It is named in honor of former Mayor Russell G. Lloyd, Sr., who was assassinated after leaving office in 1980. In the spring of 1983, buildings in the expressway's path began coming down and construction officially started on July 29, 1983. Motorists endured five years of detours and construction as the expressway was built through the heart of the city.
