The cast-in-place cantilever box girder bridge design is the only one of its kind in Virginia. The bridge is hollow. Beneath the riding surface, the box girders are open with a width of 18 feet (5 m) and a height which varies from 12 feet (4 m) to 35 feet (11 m). Power and communication lines are carried in the hollow concrete box and run the ...

Underslung (lower-beam) launching gantry used for Skyline guideway construction (2015). A launching gantry (also called bridge building crane, and bridge-building machine) is a special-purpose mobile gantry crane used in bridge construction, specifically segmental bridges that use precast box girder bridge segments or precast girders in highway and high-speed rail bridge construction projects.
Prestressed concrete is a major advance in concrete engineering and has effectively been used in rigid frame bridge construction. [10] This is notable because it was already challenging to place standard reinforcing in a concrete rigid frame bridge. Prestressing the rebars is more difficult but was proven to still be feasible.

The bridge deck was supported by thirteen concrete girders, each spanning 160 feet (49 m). These girders were prestressed by post-tensioning four wire cables embedded in the concrete. Although this type of construction had been used in Europe for quite some time, the Walnut Lane Memorial Bridge was innovative in the United States and led to the ...
