In 2012 the Bethlehem Redevelopment Authority announced that it planed to turn the Hoover-Mason Trestle into an elevated walkway. The authority would fund this project through property taxes.

The Bethlehem Steel site became a Tax Incremental Financing District in 2000, meaning taxes normally collected for the school district will be used for redevelopment.

Although Sands owns the trestle, as well as the five remaining, 200-foot-tall blast furnaces, they were eager to see the redevelopment authority restore it.

Part of the trestle was dismantled in 2005 to build the Sands Casino. The half-mile trestle walkway now connects Sands Casino parking lot to SteelStacks. The Hoover Mason Trestle opened to the public June 25 and the views from the trestle have been described as magnificent.

The Bethlehem Steel Company's Hoover-Mason trestle once supported tracks for cars loaded with ore. The cars ran from the ore field, where Sands Casino is located today, to the blast furnaces. This ore delivery system was a vital part of the process in making iron then steel.

In the early 1900s the Chicago engineering firm of Frank K. Hoover and Arthur J. Mason designed this ore handling system. It was designed to support wide and standard gauge size railroad cars loaded with iron ore, limestone and coke. Bethlehem Steel President Charles Schwab had the trestle installed in 1907. Each car could bear a weight of 40,000 pounds of material.

The trestle continued in use until the plant closed in 1995. The names of the men who built the trestle in 1907 are in engraved in the trestle.
