BUILT In 1924 and listed in the national register of historic places
TRCE prepared the construction documents for the erosion control and rehabilitation of Bridge No. 261 over Río Prieto. 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.
The project incorporated countermeasures to mitigate lateral river migration and erosion associated with floodplain constriction at the bridge. Bridge No. 261, constructed in 1924, is listed in the National Register of Historic Places.
