Transportation leaders and local officials gathered Friday afternoon to celebrate the completion of a $380 million rail infrastructure project known as the Forest Hill Flyover, a 3-mile elevated rail corridor in the Ashburn neighborhood.
The Chicago Region Environmental and Transportation Efficiency (CREATE) Program and its partners marked the conclusion of the public-private partnership project, which is part of the 75th Street Corridor Improvement Project at the CSX Forest Hill Railyard located at 2252 W. 79th St.
In September 2024, the Illinois Department of Transportation announced the receipt of more than $209 million in funds that helped finish the flyover project, which officials have said would relieve one of the worst bottlenecks for passenger and freight rail traffic in the country.
The project was funded through a nearly $120 million federal Infrastructure for Rebuilding America grant awarded in 2018 and $260 million from the Illinois Department of Transportation, Cook County Department of Transportation and Highways, Chicago Department of Transportation and six railroads represented by the Association of American Railroads.
The Forest Hill Flyover is meant to resolve a longstanding rail bottleneck where tracks from railroads including CSX, Norfolk Southern, the Belt Railway Company of Chicago and Metra’s SouthWest Service meet.
The new structure separates freight and commuter routes, ending daily interference between roughly 35 freight trains and 30 passenger trains to improve consistency.
