A Bridge from Two Flatcars

Intelligent reuse of old railcar beds enabled the author to construct an access driveway to cross a 38-foot span without damaging the stream below.

The conventional approach--open-bottom arch culvert might have worked for the stream crossing, but it would have had a greater impact on the stream.

The approach ramps of open-bottom culverts are usually retained with stacked precast block--difficult to arrange in a neat arch and too industrial looking for the author on this site.

The excavation contractor rough-graded the access to the stream crossing.

The contractor dug trenches for setting the concrete abutments.

He leveled the trench bottoms with stone fill and gravel, then placed a series of interlocking precast blocks.

At grade, the abutments transition from plain rectangular blocks to blocks with a precast faux-stone face.

Note the silt fences--required during construction--behind the cast concrete faux-stone abutments.
