We studied stabilization alternatives for the structure and the railing and designed the fix(es) for the aqueduct. We oversaw the stabilization work including pointing, stitch grouting, scour repair of the piers, and the replacement of a 1973 rail section with a new code compliant, railing referencing the original railing. The greatest damage to the aqueduct during floods is from debris propelled down the river by the flood. The debris batters the structure, is caught by the railings, and tears them away with their stonework. When a flood is anticipated, the Park Service takes down our railings, designed to be removable.

The Monocacy aqueduct was formally re-dedicated in 2005 with fanfare and a first lady. It now carries the heavily used C & O towpath over the river.
