Safety is a top priority for ODOT and IBI Group is a proud partner on multiple projects aimed at improving safety and ease congestion on I-75, 增加区域流动性, and provide transportation solutions that are compatible with local land use plans.
I-75穿过山谷
I-75穿过山谷 is an eight-phase project involving the widening and reconstruction of seven miles of I-75 from Paddock Road to I-275. 位于辛辛那提市区, I-75 is a primary NAFTA corridor which serves more than 144,000 每日车辆数目 with trucks representing 19% of that traffic. IBI’s work across the I-75穿过山谷 corridor is following ODOT’s 14-Step Project Development Process for Major 项目.
ODOT’s $94 million contract for Phase 1 and 2 consists of widening and reconstruction of 2.7 miles of I-75 between the general limits of Shepherd Lane to Glendale-Milford. A complex phasing plan is required to maintain traffic, including close coordination with utilities to relocate and upgrade electric, 卫生下水道, 通信, 生活用水和工艺用水设施.
Another key element of the project is the modification of the access to the General Electric Jet Engine factory. High speed one-way collector distributor roads and fly-overs were eliminated and replaced with a safer local, 双向道路. The project reconfigures and re-builds two interchanges and includes three bridges, 十个挡土墙, 三个环岛和一条人行隧道. Other plan elements include all new 照明 for the interstate and local roads, 噪音墙, 斜坡计量, 交通监控, 十个交通信号灯, 美观的设施和新的排水系统.
IBI Group is now completing detailed design for the remaining phases of I-75穿过山谷 (Phase 3 to 8). The estimated total construction cost for all eight phases adjusted for inflation is over 3.7亿美元.
