Chesapeake Bay Bridge Replacement Sections

A customer presented a considerable engineering project to Clark Machine, they required the construction of six replacement span sections for the Chesapeake Bay Bridge. This project exemplifies Clark Machine’s outstanding ability to cope with the challenges posed with physically large construction projects.

Clark employed a series of fabrication processes to create the new spans. Drilling, CNC plasma cutting, press brake forming, welding, and grinding formed the main set of production procedures, along with galvanization and assembly. ASTM A615 Grade 60 Steel, ASTM A709 Grade 36 Structural Steel Plate, and ASTM A709 Grade 50 Structural Steel and A325N Hardware were selected as the construction materials. Certified weld inspectors and a dedicated project manager ensured progress and quality control in line with the customer’s timeline.

Clark’s prior work in large, projects such as this one, exhibit their ability to navigate local and state bureaucracies related to public works projects in general, ensured that a complete product was delivered on time according to a stringent customer-determined schedule. A strong commitment to the customer’s needs was present, rendering them a trouble-free and productive experience.

Clark Machine strives to offer this class leading level of service, and continues to do so in each of its fabrication projects, no matter how large or small. Contact Clark today to learn more.
