The end has come for regular weekend interruptions to CTA Blue Line service.
This is the last weekend for service cuts to the Blue Line subway due to a track repair project.
Rail service between the Blue Line's Clark/Lake and UIC-Halsted stations will be suspended this weekend from 10 p.m. Friday until 4 a.m. Monday. Shuttle buses will substitute for rail service.
The CTA has been using $88 million in federal stimulus money to replace about seven miles of track from Division on the O'Hare branch of the Blue Line to Clinton on the Forest Park branch. The repairs primarily were to prevent the development of "slow zones," in which trains have to run slower than normal for safety.
Since April, crews have been replacing deteriorated wooden half ties with concrete half ties, running rail, and contact (third) rail. Beginning last spring, interruptions were made to Blue Line subway service to allow for track repairs almost every weekend.
In the coming weeks, Blue Line trains operating between Clark/Lake and UIC_Halsted will run on single tracks late at night while crews complete remaining detail work.
