Jeffery Jump
The J14 Jeffery Jump is an express bus service in Chicago. It is the first Chicago Transit Authority bus route to incorporate some features of bus rapid transit, such as transit signal priority and bus lanes. Transit signal priority takes place from 71st Street to 83rd Street. The bus lanes along Jeffery Boulevard are only available from 67th Street to 83rd Street/South Chicago Avenue during rush hour. The route mostly runs concurrently with 15 Jeffery Local south of 67th Street.
History
J14 Jeffery Jump was previously 14 Jeffery Express without bus rapid transit features.The bus rapid transit project along Jeffery Boulevard was planned as part of a larger proposal to add multiple BRT routes along certain bus corridors, which was advocated by the Metropolitan Planning Council.
In 2010, the CTA was awarded $11 million in federal grant to build a bus rapid transit route along Jeffery Boulevard. The route was planned to have bus lanes available only during rush hour periods, transit signal priority, and a queue jump lane at 83rd Street/South Chicago Avenue.
On September 18, 2012, a few months before operation began, the new route was branded as "Jeffery Jump" with a unique light blue color scheme associated with the route.
The Jeffery Jump began service on November 12, 2012; in 2013, transit signal priority between 71st Street and 83rd Street went into effect.
Since March 3, 2025, the Jeffery Jump is one of the first select services to receive a headway of at most 10 minutes under the Frequent Network program.
