| 摘要： | The Illinois Department of Transportation (IDOT) District 4 was faced with a major challenge. The eastbound McClugage Bridge, which carries U.S. routes 24 and 150 over the Illinois River in Peoria, needed major rehabilitation, forcing the newer westbound span to carry 2-way traffic while the older bridge was repaired. Major traffic congestion problems were foreseen for commuters. To place both eastbound and westbound traffic on the adjacent newer structure would require a positive separation of traffic, which would provide a maximum of 3 lanes. To accommodate rush hour traffic needs (2 lanes in the direction of peak hour traffic and 1 lane in the opposite direction), a decision was made to use the QuickChange Moveable Barrier (QMB). This article describes the QMB system, IDOT's decisionmaking process, potential problems that were considered, and the largely successful result of using the QMB system to deal with the temporary bridge closure. |
