EXISTING BRIDGE Date of Construction: 1901 Age: 103 years Engineer/Builder: Nelson and Buchanan Co., Chambersburg and Pittsburgh, PA BRIDGE HISTORY Efforts to bridge the Clarion at this location began in 1882 with petitions filed by the residents of Arroyo, it was determined that a bridge was not feasible at that time. Local residents formed the Arroyo Bridge Company and built a toll bridge that operated until 1899. The residents petitioned the county to purchase the bridge and make it free of tolls. The courts agreed and the bridge was purchased by Elk County. Two years later the bridge was replaced by the current structure. The bridge was an important structure to the community of Arroyo, during summer dances and other social events were held it. Unfortunately, the structure has exceed its useful service life and no longer meets current design standards. PROJECT HISTORY The efforts to replace the bridge began in 1992. P. JOSEPH LEHMAN, Inc. began engineering services in 1992. Funding for the project was secured in 1996. Preliminary design and environmental evaluation began in 1998. Environmental clearance was received in July 2001. Design approval was received in October 2003. Construction was awarded to Glenn O. Hawbaker in 2004. The bridge was completed in November of 2004. BRIDGE DESIGN For the design of the proposed bridge, P. JOSEPH LEHMAN, Inc. had to consider the Federal Wild & Scenic River designation of the Clarion River. It was determined that a standard concrete structure would not be appropriate because of the scenic values of the river. After several meetings, it was determined that the new bridge would be a weathering steel I-beam structure with a concrete deck and open rails. This provides a structure that appears thinner and will provide motorists the opportunity to enjoy the view of the river from the bridge. The piers and abutments will be reinforced concrete that will be constructed with form liners and dye to look like the masonry substructures of the existing bridge. The weathering steel and dyed concrete will give the bridge colors that blend with the surrounding environment. Construction cost approximately $2.39 million.
EXISTING BRIDGE Date of Construction: 1894 (center spans); 1905 (small end spans) Age: 113 years Engineer/Builder: Nelson and Buchanan Company, Chambersburg and Pittsburgh, PA BRIDGE HISTORY Efforts to bridge the Clarion River at this location began in 1883 with petitions filed by the residents of Hallton and Maxwell Run, it was determined that a bridge was not feasible at that time. The residents petitioned the county courts again in 1889. The county agreed and approved the construction of the bridge. The bridge would provide a safer crossing than the existing stream ford that was located near this location. The bridge was built in 1891. By 1905, the small end spans needed to be replaced. Unfortunately, the structure has exceeded its useful service life and no longer meets current design standards. PROJECT HISTORY The efforts to replace the bridge began in 1992. P. JOSEPH LEHMAN, Inc. began engineering services in 1992. Funding for the project was secured in 1996. Preliminary design and environmental evaluation began in 1998. Environmental clearance was received in January 2001. Design approval was received in October 2003. Construction awarded to Glenn O. Hawbaker in 2004. The bridge was completed in November of 2004.
