U.S. Route 30 Business (US 30 Bus.) is a 19-mile (31 km) business route of US 30 in Chester County, Pennsylvania. The route follows the former alignment of US 30 between Sadsbury Township and East Whiteland Township, passing through Coatesville, Downingtown, and Exton. US 30 follows a freeway bypass between these two points. The present alignment of US 30 Bus. was originally part of a turnpike called the Philadelphia and Lancaster Turnpike that was completed in 1794. The state took over the turnpike at the beginning of the 20th century. In 1913, present-day US 30 Bus. was incorporated into the Lincoln Highway, an auto trail that ran from San Francisco east to New York City. The Lincoln Highway through Pennsylvania became Pennsylvania Route 1 (PA 1) in 1924. US 30 was designated concurrent with PA 1 west of Philadelphia in 1926, with the PA 1 designation removed two years later. US 30 was widened into a multilane road through Chester County in the 1930s. In the 1960s, US 30 was moved to a freeway bypass around Coatesville and Downingtown, with US 30 Bus. designated onto the former alignment of US 30. In 1995, US 30 Bus. was extended east when US 30 was extended to bypass Exton.
