Today I boarded southbound Red Line trains with unfamiliar destination signs. One said it was headed to Roosevelt as its last stop. The other noted Ashland/63rd as its terminus. And no, I was not time-traveling back to the 1980s and early '90s, when the Red Line south traveled along the now Green Line tracks.
Yes, the Red Line south track reconstruction has officially commenced. Red Line south riders can find their way north and back home home at redlinesouth.com. And the Chicago Tribune has developed this map with some of the suggested service alternatives.
