Topic:  The I-26 Green River Bridge Rehabilitation

Presentation: Video

Summary: The I-26 Green River Bridge is the highest Interstate Highway-carrying bridge in North Carlina at 225 feet tall. Built in 1968, the bridge spans the Green River south of Asheville with parallel nonredundant steel tension member 2-girder steel structures with a main unit having spans of 260’-330’-260’. John Sloan, PE, AECOM’s North Carolina Bridge Program Manager, and Tim Sherrill, NCDOT Bridge Preservation & Repair Engineer, will give a presentation on the rehabilitation project that consisted of strengthening and rehabilitation of the bridges that included:

  • Adding cover plates

  • Adding stiffeners

  • Replacing the existing lightweight concrete decks with a new single lightweight concrete deck

  • Adding shear studs to the girder and stringer top flanges to make them composite

  • Tying the two bridges together with floor beams to make them a single structure

  • Widening the deck

The project team has provided a feasibility study, final design, design phase load testing, and construction phase services that include the instrumentation and monitoring of the structure. All steel rehabilitation and strengthening work is complete, two phases of deck pours are complete, and the final phase of the deck replacement work is anticipated to be complete this year.
