一个复杂且交通堵塞的立交不得不被取代.

At what once was the crossroads of 达拉斯-to-Kansas City trail drives and the Chicago-to-Los Angeles trade route, 两条州际公路, I-44和I-235, 现在相交. Increasing transcontinental traffic on the I-44 corridor and a heavily traveled north-south railway created the need for a critical and challenging update to the interchange. 班, 哈斯克尔公司, 是因其团队对交换的大局观而被选中的, 对施工交通控制的深刻关注, strong bridge design staff and innovative solutions to minimize disruption to the traveling public.

我们在这个前所未有的项目中引入了突破性的技术.

The project was divided into five construction contracts with a total estimated cost of $220 million, the largest project cost in the Oklahoma Department of 运输 (ODOT) history at the time. 该项目的两个阶段是该州历史上重要的第一次. One was the first four-level highway interchange on the ODOT highway system. 另一个是架设两个铁路桁架, each measuring 275 yards long and 45 feet high and weighing 2 million pounds, 为BNSF铁路提供一条主干线. 班 crafted project documents that instructed the contractor to use Accelerated Bridge 建设 (ABC) techniques, performing truss member assembly 1/4 mile north of the final location and using Self-Propelled Modular Transports (SPMTs) to move the trusses into position.

规划 and innovation allowed minimal disturbance and early completion.

班’s innovating planning allowed the bridge move-in to occur with the highway’s full closure over a two-and-a-half-day weekend. 高速公路停车是为了让列车畅通无阻, 然而，工作几乎比计划提前了整整一天结束, 在周一早高峰时间之前. 进一步, retaining walls of up to 30 feet in height were designed using adjoining drilled shafts in a “tangent pile” configuration to retain existing embankments. This innovative construction technique allowed the project to proceed without relocating the adjoining businesses or interfering with the railroad embankment. 最终, with careful planning by ODOT and 班 and skillful execution by the contractor, the project was completed nearly a year ahead of the original schedule.
