Improvement to Bridge 261 over Prieto River
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 261 in Maricao, Puerto Rico. Bridge 261 is a three (3) span reinforced concrete cast-in-place structure built in 1924 and is listed in the National register of Historic Places (NRHP). The design strategy consisted of providing a sustainable, environmental friendly and economically feasible structural control to prevent future erosion. Project includes conservation/retrofit works at bridge structure and road safety improvements. Construction documents include environmental evaluations, Documented Categorical Exclusion (FHWA and NEPA-compliant), hydrologic-hydraulic/scour analysis, bridge general structural assessment, design drawings, technical specifications and permits/consultations. Extensive coordination with the State Historic Preservation Office (SHPO) and Instituto de Cultura Puertorriqueña was performed pursuant to 54 USC 30-6108, 36 CFR Part 800 and Puerto Rico Law 112. SHPO concurs with the PRHTA determination that a finding of no adverse effect would be appropriate for proposed undertaking.
