Why It Matters
A wave of extreme heat began affecting Chicago on Tuesday, prompting the National Weather Service to issue warnings for dangerous heat conditions over two consecutive days.
CHICAGO -- A major bridge in downtown Chicago remained stuck in the raised position for more than four hours Wednesday after dangerous heat caused its components to expand.
The DuSable Lake Shore Drive bridge, which crosses the Chicago River at Grand Avenue, became stuck during a scheduled lift to allow a boat to pass underneath around 10 a.m., said Erica Schroeder, a spokesperson for the Chicago Department of Transportation. The bridge finally lowered and reopened to traffic shortly before 2:30 p.m.
“The issue was related to the high temperatures in Chicago, which caused bridge components to expand enough to prevent the two bridge leaves from fully closing,” Schroeder said in an emailed statement.
City crews, assisted by the Chicago Fire Department, “made the necessary adjustments” to cool the bridge, Schroeder said.
A wave of extreme heat began sweeping across Chicago on Tuesday, prompting the National Weather Service to warn residents on two consecutive days to prepare for “dangerous heat.”
The stuck bridge caused traffic snarls downtown as drivers were forced to take other routes.
