US EditionImplosion will take down a nearly century-old Mississippi River bridge
The nearly 100-year-old Black Hawk Bridge will be imploded to allow construction of a safer $140 million replacement expected to open in 2027, carrying 2,100 vehicles daily.
- The Black Hawk Bridge is scheduled for a controlled implosion Friday to remove the nearly 100-year-old Mississippi River crossing, with officials expecting a large crowd and streaming the center span detonation live.

- The demolition plan calls for crews to detonate the center span first, then remove the eastern section, while the western span will be disassembled because parts overlie homes and a railroad.
