Rail service between the Jefferson Park and Harlem Blue Line stations will be temporarily suspended from 9 p.m. Friday, December 7 to 3 a.m. Monday, December 10 in order to replace deteriorated rail ties, tie plates and spikes. Bus shuttles will operate as a substitute for rail service between the Jefferson Park and Harlem stations. Extra travel time is advisable.
From 10 p.m. Friday to 11 a.m. Saturday one inbound and one outbound lane of traffic will be closed on the Kennedy Expressway from Jefferson Park to Harlem.
The work is part of an aggressive plan to eliminate slow zones on the O'Hare branch of the Blue Line and redesign the tracks to allow trains to reach speeds above 60 mph.# # #
