CN - State Street Bridge
Posted January 6, 2019, by John Marvig (marvigj27 [at] gmail [dot] com)

Not hard to see why these five bridges (Clark, Dearborn, State, Wabash, Michigan) will be replaced this year. The State Street bridge is probably in the worst immediately visible condition, with a massive sag in the west abutment. To counter this, temporary timber cribbing has been added under the girders, but is beginning to fail. All five bridges have advanced pier and deck deterioration, and most have had additional cribbing and bracing added.
