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

Blue Line trains in both directions will operate on the same track between the Grand and LaSalle stations from 11 p.m. Sunday until 4 a.m. Monday while crews perform track maintenance, 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 Clark/Lake, Washington, Monroe and Jackson stations.

On the Brown Line, planned maintenance work between the Belmont and Irving Park stations scheduled for Sunday have been canceled.

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