Blue Water Bridge - Michigan 3D Utility Model

T2ue provided SUE services including utility locating, sanitary sewer and manhole characterization, and designating other utilities within the limits of the toll plaza and both bridges up to the US border.

The Blue Water Bridge (BWB) spans the St. Clair River and carries international traffic between Port Huron, Michigan and Point Edward and Sarnia, Ontario. Located near the I-94 and I-69 interchange, the bridge forms a critical gateway linking Canada and the United States.
In 2018 the Michigan DOT advertised a RFP to design a three dimensional (3D) utility model which includes all utilities located in, on and adjacent to the bridges, the BWB properties and the toll plaza. The 3D utility model will provide fast and clear identification of all utilities.
To support the design of the 3D utility model, LiDAR was used to provide a single point cloud and a design survey of the US toll plaza for the BWB and surrounding properties. T2 Utility Engineers provided SUE services within the limits of the toll plaza, relocated customs/duty free areas and both bridges up to the US border. T2ue designated approximately 100,000 linear feet of buried utilities to date, within the project limits and provided electronic depths along each designated buried utility. T2ue assisted the client with identifying the utilities within the utility tunnel that runs under the toll booths, reducing the utility related risk and project delays.
Following scheduling challenges related to the COVID-19 pandemic, the bridge is now open and fully operational, connecting the United States and Canada.
