The J14 Jeffery Jump (previously known as the 14 Jeffery Express) is a Chicago Transit Authority-operated express bus service in Chicago. It represents the CTA's inaugural bus route to incorporate elements of bus rapid transit, such as transit signal priority between 71st and 83rd Streets, along with dedicated bus lanes on Jeffery Boulevard stretching from 67th Street to 83rd Street/South Chicago Avenue during peak travel times. South of 67th Street, this line largely parallels the 15 Jeffery Local route.

History

Initially running as the 14 Jeffery Express without any BRT enhancements, the J14 underwent improvements as part of a larger initiative to establish several BRT corridors promoted by the Metropolitan Planning Council. In 2010, the CTA received an $11 million federal grant aimed at developing this BRT corridor, which included implementing rush-hour bus-only lanes, transit signal priority, and a queue jump lane at 83rd Street/South Chicago Avenue.

The service was rebranded as "Jeffery Jump" in September 2012, adopting a unique light blue livery. Operations commenced on November 12, 2012, with transit signal priority becoming active in 2013.

Under CTA’s Frequent Network program launched in March 2025, the Jeffery Jump now maintains intervals of ten minutes or less, enhancing both frequency and dependability along this important South Side transit corridor.

Service

The route extends from 103rd/Stony Island (103rd Street Garage) located in South Deering to Washington/Jefferson within Chicago’s Near West Side, primarily traveling along Jeffery Boulevard, Lake Shore Drive, and utilizing the Loop Link bus lanes; it is important to note that buses do not make stops on Lake Shore Drive. South of 67th Street, its path largely coincides with that of the 15 Jeffery Local.
