Rehabilitation and Scour Mitigation of Bridge 1096

TRCE prepared the construction documents for the erosion control and rehabilitation of Bridge No. 1096 in San Germán, Puerto Rico. The construction documents included environmental evaluations; a Documented Categorical Exclusion (FHWA- and NEPA-compliant); hydrologic, hydraulic, and scour analyses; a general structural bridge assessment; design drawings; technical specifications; and required permits and agency consultations.

Bridge No. 1096 is a thirteen (13) span reinforced concrete cast-in-place structure constructed in 1969. The project incorporated countermeasures to prevent lateral river migration and erosion caused by floodplain constriction at the bridge.
