Cortland Bridge replacement push puts landmark protection in question

Updated 2026
A proposal to replace the closed river crossing has opened a debate over what should survive of Chicago’s pioneering drawbridge.
The future of the Cortland Street Bridge has become a dispute over preservation as well as transportation. September reporting describes Alders Brian Hopkins and Scott Waguespack seeking removal of the 1902 bridge’s landmark protection to pursue a replacement.

A different future from the announced repair
The earlier restoration plan envisioned improvements to the deck, sidewalks, railings, lighting, structure, and bridge house. Preservation Chicago’s account described a vehicle closure beginning in September 2025 and an expected 18–24 months of construction.
The replacement push changes the question from how the bridge will be repaired to whether the historic structure will remain. Hoodline’s September 8 account attributes that push to the alderpeople’s desire to restore the crossing more quickly. It does not document a completed legislative action.
A bridge with a second possible role
ASCE identifies Cortland as the first American trunnion-bascule bridge, an early model for Chicago’s later movable crossings. Its significance rests on a particular engineering solution, with counterweights and rotating leaves making room for boats while carrying streets over the river.
Newcity’s September 10 summary of Block Club reporting describes preservationists considering reuse, potentially in connection with the 606. That possibility deserves evaluation on its own terms: what it would retain, whom it would serve, and who would maintain it.
The decision still ahead
A proposal to remove protection is not the same as an adopted ordinance. The next evidence to follow is the legislative text and any public engineering comparison of repair, replacement, and reuse.
Residents need a dependable crossing, and the city needs a clear account of the choices available. Publishing the scope, cost, and access consequences of each option would make the tradeoffs visible before an irreversible decision.
