美国1/138号公路交叉口的改善

项目总结

在138号公路(联合磨坊路)和Tunstall Drive的交汇处,沿美国1号公路(梅克伦堡大街)在南山镇完成了道路改善工作,以重新调整Tunstall Drive。该项目还沿美国1号公路修建了转弯车道,并在十字路口安装了新的交通信号灯。 该项目包括沿现有的1号公路(N. Mecklenburg Ave)加宽约0.22英里的道路,完全在South Hill镇的范围内。由于与拟议设计存在水平和垂直冲突,因此需要进行公用事业搬迁–包括输水管线,输气管线,电线杆和电信调整。

The intersection enhancements were crucial to improve the safety and operational efficiency of the US Route 1 corridor. The project was motivated by traffic growth due to the newly completed VCU Health Community Memorial Hospital facility and the 1.5 million square feet of developable land in the 138-acre Hillcrest Industrial Park just south on Tunstall Drive. The civil engineering site work of the hospital facility, which opened in 2017, was also completed by 蒂蒙斯集团.

蒂蒙斯集团’的交通工程师设计了改进措施,将Tunstall Drive向东移动约25英尺,以使整个路口对齐。 Tunstall Drive的重新布置和交通信号灯的添加将在导航十字路口时提高驾驶员的安全性和运营效率。 考虑到138号公路沿线的现有商业用途以及Tunstall Drive上拟议的经济发展地点,该十字路口在设计时考虑了较大的重型车辆。

The finished road design included turn lane design, US Route 1 corridor redesign, and a new traffic signal at the intersection. 蒂蒙斯集团 also provided survey, environmental, geotechnical services and construction administration for the project.
