Description 

Demolition of the open-spandrel arch spans began in June 1992. The crews were nearly done demolishing the first of the three main spans, and was cutting through the final reinforcement rod (the tendon, if you will). Once the tendon of the first span was severed, a chain reaction occurred with the other two arch spans: they collapsed under their own weight onto the railroad tracks below, causing one huge problem. Railroad traffic was backed up for days as demolition crews worked to clear the collapsed spans from the tracks. It turns out that the supports of the three main spans were dependent on each other.

Another lesson to be learned in building huge bridges of this type and design (read the HAER report).

Originally built by William P. Carmichael Construction Company, as noted in his obituary.

In '93, the rebuilt bridge was christened with a plaque at its NW end and dubbed "The Bridge Across St. Louis" as part of a ceremony recognizing racial division and seeking healing between the north and south sides of the city. The bridge is a symbolic dividing line between the city's north and south sides.

The South Side has been, and continues to be, predominantly white while the North Side continues to be predominantly black. Then Mayor Freeman Bosley Jr. was master of ceremonies for the event. Bosley was St. Louis' first African-American mayor. Community organizations from both sides of the bridge -- Churches Committed to Community Concerns (from the outh Side) and Churches Allied for Community Improvement (from the North Side) orchestrated the event.

The replacement bridge had way too many lights on it (over 200 of them) and finally succumbed in 2010 to the pain of St. Louis City facing a multi-million dollar budget shortfall. In July the city removed all the orange lights. Every other light stand has now been replaced with a single lighting fixture.

The lighting on the old bridge is how it should be. The new bridge has way to many lights on it. It has a double light every ten feet or so, and tall lights to light the road. The city should remove some of those lights. They have better things to do with the money then pay the electric bill for those lights.
