Steel Multigirder Bridge Replacement Project

Location: Elba, NY

Owner: Genesee County

Status: Completed

Construction Cost: $1 Million

The Project

This $1 million Locally Administered Federal Aid (LAFA) project involved replacing a single-span open grate-deck steel multigirder bridge over a drainage ditch with a new bridge. Erdman Anthony participated in all the design phases and performed construction inspection services for the project.

Features/Solutions

The new bridge consists of a 24-foot-span three-sided precast-concrete buried structure founded on an invert slab embedded below the stream channel, in accordance with environmental regulations and to mitigate necessary pile driving. Precast-concrete wingwalls contain the roadway embankment in the agricultural area.

Ancillary improvements involved improving roadway geometry to conform with current standards, installing new guiderails, and placing stone-fill scour protection to prevent erosion. The proximity of the adjacent roadway necessitated the design of temporary sheet-pile retaining walls with tiebacks to facilitate excavation.
