Civil Engineering magazine featured the reinvented Hoover Mason Trestle walkway at the historic Bethlehem Steel plant in Bethlehem, Pennsylvania, in its April 2016 issue. Simpson Gumpertz & Heger (SGH) employees Matthew Johnson and Eric Twomey, and Charlotte Bouvier of Hoyle, Tanner & Associates (formerly of SGH), wrote the article “Connecting Past and Present,” which describes how the project team transformed a trestle that once carried iron ore to the steel plant into an elevated pedestrian walkway connecting a new casino and entertainment complex. SGH served as the structural engineer on the project.
The authors describe the design considerations and challenges of the project, and review changes made by the team during construction to reduce project costs. “The project provides an important resource for pedestrian connectivity at the multifunctional community site and a window into an ‘archaeological’ site that symbolizes and celebrates the rich industrial history of the Lehigh Valley,” they conclude.
