Route 22/322 Bridge at I-81
On May 9th, 2013, a tanker truck crashed on a ramp beneath the Route 22/322 overpass at the massive I-81 interchange near Harrisburg, PA. The resulting fire damaged the bridge, which required emergency replacement.
On May 23rd, High Steel was awarded a fast-track contract by PennDOT to fabricate the replacement steel for the project. Steel was ordered that same day and arrived from the mill 11 days later.
Fabrication on the 365-ton project began immediately, and steel delivery began on August 9th. The project's general contractor, G.A. & F.C. Wagman, awarded High Structural Erectors the subcontract to erect the steel for the new bridge. The erection of the 30 I-girders and two box girders began on August 12th and was completed on August 26th. In all, 95 calendar days elapsed between the notice to proceed to the completion of the erection.
