Movable traffic

Minimizing community impacts during construction has become a priority in bridge construction. This article takes a look at bridge construction projects where technically challenging bridges have been constructed with minimal community impacts through contractors using innovation and forward-thinking. Two such cases are the West 7th Street Bridge in Fort Worth, TX and new pedestrian bridges at San Diego International Airport's Terminal 2. Traffic was allowed to remain in its original configuration throughout most of the project in both cases through the use of pre-fabricated pieces and taking an aggressive approach to the schedule with a shortened closure time. The Sellwood Bridge in Portland, OR is another example cited, as it is slated to be reconstructed with the use of a detour bridge. The reconstruction of Loop 375 Transmountain West in El Paso, TX is another example where four concrete bridges are being constructed during live traffic. Finally, the Cordes Junction Traffic Interchange project in Arizona is presented as an example of construction over an interchange without closing the roadway, using falsework built on top and then removed after the bridge was post-tensioned.
