The Green Line Improvements project will largely focus on track replacement and structural repairs.
This funding would support track improvements on both sides of the Lake Street Bridge, which is
scheduled to be completely replaced by the Chicago Department of Transportation in 2023. The scope
of the project will include: improve the curve geometry on the east side of the bridge; replace the
timber ties and rail fasteners, install new gauge planking, replace equipment at both the east and west
turnouts, and replace structural steel framing for the three side platforms adjacent to the track.
