I-95 / I-695 Interchange, Phase 1

High Steel was contracted to fabricate, deliver and erect over 16,000 tons of structural steel for the Maryland Transportation Authority's first I-95/I-695 Interchange contract. The structural steel fabrication encompassed 11 bridges built in 17 stages of construction. The project's aggressive delivery schedule prompted High Steel to tap into its workforce's vast knowledge base for new ideas.

High Steel was able to exceed delivery expectations without sacrificing quality by introducing innovative processes to an industry steeped in tradition. For example, High Steel's engineering group implemented a shop drawing process entitled Design Intent. Design Intent reduced the number of shop drawings submitted for owner approval by over 60%.

High Steel's Field Operations group (now High Structural Erectors) erected four large multi-span curved flyover bridges and two straight plate girder bridges for the project.  The six cranes six ranged from 60 to 300 tons in capacity. We also designed and erected shoring towers at mid-span to support the ramps, which were as high as 110 feet.

The I-95 / I-695 project is part of the Maryland Transportation Authority's multi-year $450 million I-95 Express Toll Lanes project.  Phase 1 was constructed by a joint venture between G.A. & F.C. Wagman Inc. of York, PA; Corman Construction Inc. of Annapolis Junction, MD; and McLean Contracting Co. of Glen Burnie, MD.
