Park One Railroad Spur
32′ Span x 10; Rise Arch Box

A mile-long railroad spur was constructed by Delaware County, Indiana, with additional federal funding to link an industrial park to a major rail line.

R.W. Armstrong specified a precast concrete three-sided arch to carry the rail line over a stream that intersected the line on a 30 degree skew. To keep costs down, the headwalls were sloped to follow the proposed grading and minimize concrete use. The ECO-SPAN® Arch-Box, specially designed for Cooper E-80 railroad loading, was chosen by Beaty Construction, the bridge sub-contractor.

The all-precast superstructure including bridge units, headwalls and wingwalls is supported by driven H-piles and a cast-in-place pile cap.
