CHICAGO (STMW) – Late night Blue Line riders should allow extra travel time this week as overnight construction is expected to cause minor delays.

Blue Line trains in both directions will operate on the same track between the Jackson and Racine stations from 11 p.m. Sunday until 4 a.m. Monday while crews perform maintenance work, according to the CTA’s website. The work will continue at the same times the rest of the week, ending early Friday.

As a result, passengers must board and exit all trains on the O’Hare bound side of the platform at the LaSalle, Clinton and UIC-Halsted stations, the CTA said.

Minor delays are expected and passengers are advised to allow extra travel time.
