Expect late-night and weekend delays on CTA Brown Line L trains starting Sunday as the transit agency begins work on a multiyear, $71.2 million project to repair the track and supporting structure between Armitage and the Merchandise Mart.

The work will get rid of more than 70 percent of the “slow zones” along the “Ravenswood connector” that carries 40,000 riders on the Brown Line and the Purple Line Express every weekday between Armitage and the Loop, according to the CTA.

It’s to be completed in 2015.

The work will be done mostly late at night and on weekends.

During that time, Brown Line L trains will continue to operate in both directions but will alternate on a single track, causing delays and occasional changes in boarding locations at stations,accordin gto the CTA.

Work is to begin on the first stretch — between Armitage and Sedgwick — at 7 a.m. Sunday. The work Sunday is expected to continue until 9 p.m.

Southbound trains will switch to one track after leaving the Fullerton station for Armitage.

During the work Sunday, riders will board on one side of the station between 7 a.m. and 1:30 p.m., then will switch to the other side for the rest of the day.

Similar work will be done between other stations for the remainder of the project. Riders will get a couple of days notice via alerts on the transit agency’s website.

The Ravenswood onnector work is being done in two phases — the first will repair the steel infrastructure, and the second will replace deteriorating rail ties.

“The Ravenswood connector’s condition has resulted in numerous ‘slow zones’ that require trains to operate at maximum speeds of 15 mph,” CTA President Forrest Claypool said. “This project will . . .eliminate more than two miles worth of slow zones.”

The elevated rail and track between Armitage and the Loop was built in the late 1800s.
