The Bethlehem Redevelopment Authority revitalized the historically significant Hoover-Mason Trestle (HMT) as part the former Bethlehem Steel 160-acre site redevelopment. Its adaptive reuse goal was to use the existing trestle structure – a former steel interior ore rail line – to create connectivity via a pedestrian promenade.
As a unique, one-of-a-kind structure, constructing the HMT proved a challenge. The fourth longest of six known elevated walkways worldwide, there were few engineering and design examples to help estimate costs. Conceptual designs and programming adjustments were necessary to accommodate the budget. Boyle facilitated matching the project goals to the budget. Yet, even with this effort, original design base bids were high. Boyle collaborated with the project team on extensive value engineering to eliminate $3.7 million in costs and another $1.7 million during construction to meet the Authority’s budget.
With many SteelStacks campus outdoor events planned during summer, Boyle strategically worked through the winter to construct the HMT. Construction started in October 2014 and was completed on schedule for the summer season in June 2015.
The HMT, which once carried cars filled with ore to the blast furnaces, is now part museum, part circulation walk and part attraction, tying together an arts and entertainment complex.
