So, a main span was in the plans, instead, and the Army Corps approved of the design. Construction on the bridge started in 1969, and it was opened to traffic on March 2, 1973 (along with the East Loop of I-610). Just a year before, the

claimed the struts were an even more dangerous hazard to ships that must veer from the middle of the waterway. By some accounts, port officials protested, but TxDoT did not listen to their pleas. The bridge cost TxDoT $19 million in its current configuration; a higher clearance would have cost more, and the agency went on to investigate that ships did not need . This decision proved to be a mistake. Several ships have collided with the bridge over 27 years, but despite this, the bridge only suffered minor damage and was still intact. That all changed in December 2000, when a cargo crane struck the bridge, knocking a hole in the concrete deck and damaging a steel beam. The damage took six weeks to repair, forcing several lanes to be closed in the process. The worst accident, though, happened in May 2001, when a freighter's cargo boom caused severe damage to a girder and put another gaping hole in the span. Several lanes of the bridge were closed for two months while repairs were completed.
