About this Project

The purpose of this project is to perform engineering and environmental analyses that will result in a long-term solution for the replacement of Chester County Bridge No. 134 in compliance with current regulatory and design criteria. American Engineers Group, LLC (AEG) is responsible for geotechnical engineering, environmental documentation, environmental permitting, and hydrologic and hydraulic analysis.

The Chester County Bridge #134 (North Reeds Road) crossing of the East Branch of Brandywine Creek in Upper Uwchlan and East Brandywine Townships, Chester County, was built in 1939 and is a two-span, steel multi-beam bridge founded on stone masonry substructures. The bridge has a total length of approximately 82 feet with two simple spans of 40 feet. The bridge has a curb-to-curb width of approximately 19 feet. There are no sidewalks on the bridge or approaches to the bridge. The proposed replacement structure will be a single-span bridge.

AEG performed an online Pennsylvania Natural Diversity Inventory (PNDI) Database search to verify the absence of federal and state-listed plant and animal species. A Wetland Identification and Delineation memorandum was prepared to document the wetland identification procedures and findings, including field data forms and mapping of the project site and outlining the functional assessment will be updated and submitted to the Pennsylvania Department of Environmental Protection (PADEP) for review, comment, and permit application.

A detailed hydrologic and hydraulic analysis was performed to determine existing flooding conditions and analyze the proposed project’s potential hydraulic and regulatory impacts following PADEP requirements.

AEG prepared a Boring Location Plan and is responsible for the subsurface investigation and testing, including PennDOT-certified test boring field supervision and in-house laboratory testing. The foundation design report will be prepared after the completion of the structure test borings.
