SH 33 Historic Bridge
CP&Y completed an Environmental Assessment (EA) for the replacement of a historic bridge within a historic district in the City of Guthrie, Oklahoma. The proposed project was in a low-income area and required more than a dozen relocations within a historic district as well as right-of-way from an adjacent park.
Work included a socio-economic analysis, completion of an Individual Section 4(f) Evaluation, drafting the EA, providing Section 4(f) de minimis documentation, coordinating the Section 6f conversion process, and public involvement including conducting the public hearing. A Finding of No Significant Impact (FONSI) was obtained for the Environmental Assessment.
CP&Y also completed mitigation requirements for an adverse effect under Section 106 of the National Historic Preservation Act for the project. This work included preparation of an interactive GIS layer indicating the presence and absence of buildings within the NRHP-listed Guthrie Historic District, Historic American Engineering Record (HAER) documentation of the historic bridge (submitted to the Library of Congress) that included a transcribed interview with a man whose father had worked on the construction of the bridge, and a custom-designed commemorative kiosk sign documenting the history of the bridge.
