Construction on the new span, estimated to cost $33.6 million, began in 2007.
The new $54 million southbound span was opened to traffic in 1990.
Soon after the new span opened, the old bridge was demolished.
It is largely believed that the bridge will be replaced within the next five years by a new span.
The new span opened to traffic on January 15, 2008.
After three years of construction the new much wider span opens in January 2011.
Construction progressed rather rapidly on the new span once earth moving began.
To meet modern standards and to address the deficiencies of the bridge, a new span is being considered.
To minimize the effect on river traffic, the new span was installed over the course of three days.
The cost of building a new span was estimated at between $25 and $35 million.
