Work on North Side Red Line stations will take longer than a few weeks and will last into late fall, officials said Monday at a meeting in Uptown.

The Argyle, Berwyn, Lawrence and Thorndale stops will shutter for six weeks for repairs but the work on station viaducts and track slow zones will last much longer. Streets near the station will close intermittently on weekends as the work lasts into November and December.

"This work is a marathon, not a sprint," said Ald. Harry Osterman (48th), whose ward includes Andersonville, Edgewater and parts of Uptown.

The Berwyn and Lawrence stops will close in October and reopen in November but CTA work there is not expected to be completed until Nov. 30 and Dec. 28, respectively.

The Thorndale stop closed Aug. 16 and is scheduled to reopen Sept. 28 though work will not be completed until Nov. 30.

The Argyle stop closed Friday and will reopen Oct. 5 but will work will not be done until Dec. 28. A business owner by the Argyle stop told Osterman at the meeting that business was down 40 percent this past weekend, the first weekend of the station closure.

Osterman said signs on the street will help remind residents and visitors that stores are still open during construction. Also, visitors will be directed to nearby lots to park.

Earlier this year, the CTA began closing the first of seven North Side stations for upgrades. Some of this work is aesthetic--new paint and new lights--but some is more extensive, such as the viaduct work.

This month, the CTA board voted to add more slow zone and viaduct work to the project. The work is considered "interim" improvements until funding becomes available for the Red and Purple Line modernization project, which would make all North Side Red Line stations accessible for people with disabilities and could close some stations.

A CTA official at Monday's meeting said that project is "10 years out."

Meanwhile, on the South Side, the CTA is accepting comments from riders about its plan to shut down Dan Ryan stations for five months next year to overhaul the track. Comments are due on Sept. 10.

Although the 95th Street Red Line stop will close as part of this project, station upgrades will be completed separately.

The CTA is holding a meeting about 95th Street station improvement plans from 5-7 p.m., Sept. 11, at Harlan High School, 9652 S. Michigan Ave., and 6-8 p.m., Sept. 13, at Palmer Park, 201 E. 111th St.
