The New Mississippi River Bridge is the first bridge built connecting downtown St. Louis and southwestern Illinois in more than 40 years. It will feature two lanes in each direction with an estimated volume of 40,000 cars per day.
The project consists of a main span of 1,500 feet and two back spans of 635 feet. At completion, it is the third longest cable-stayed bridge in the United States
Shalom provided construction inspection, documentation of material quantities, certification review of material acceptance, interpretation of plans and specifications, along with material inspection at the batch plant inspection. Some of the construction inspection was rebar and metal inspection, turn of the nut, 7-wire low relaxation strand installation for bridge stay cables, welding inspection and post tensioned multi-strand tendon installation, stressing, and grouting as per ASTM C939. We also performed rotational capacity testing of bolts, concrete maturity monitoring through use of intellirock sensor and data, electrical items, inspection of deck panels, rotational capacity and inspection of structural steel erection as per FHWA.
