This interchange project involved the confluence of traffic arteries, 雨水排水系统和多方利益相关者.

工程 design for two new interchanges at 193rd East Avenue and State Highway 66 with U.S. 412号公路/ 44号州际公路包括分级, 排水, 桥, 浮出水面, 信号, 照明, 施工方案的签订和交换. The project consisted of urban highway and interchange design to reconstruct and widen 1.5 miles of the divided urban interstate to six lanes and widen 0.六英里长的主干道变成了四车道. Critical to success was close coordination with eight different stakeholders, including the 切罗基族国家 because of the tribe’s nearby casino and golf course.

我们的协调组织了项目的复杂动态.

班, 哈斯克尔公司, designed the project as two sequential construction contracts with an accelerated design schedule. The scope included a new complex multi-level interchange design, 州际干线出口匝道通往临街道路/当地街道, 平面交叉路口, 现浇挡土墙和隔音墙, 几何和路易斯大道大桥的建造. A hydraulic study was performed for the alteration of three existing reinforced concrete box (RCB) 桥s and the addition of one new reinforced box 桥. Hydraulic and structural design were also performed for three RCB culverts. A concrete-lined channel was designed to convey the 100-year storm effluent from the Cherokee Casino golf course’s detention pond within the limited existing right-of-way.

The results were improved traffic operations, safety and aesthetics.
