September 2, 2013. The Montrose Blue Line station on the CTA, the station I use most often these days, is one of the stations that sits in the middle of the Kennedy Expressway. During rush hour, I can see traffic on the highway fall farther and farther behind. I don't know that that remains true, though, since the Blue Line has a lot of slow spots from Logan Square to downtown. I do know it takes me about the same amount of time to ride my bike from Kostner and Argyle to Jackson and Wabash as it does for me to ride to the Montrose station and take the train downtown.
