Huie Road Sidewalk Improvements

Project Details

This project involves the engineering design and topographic surveying for sidewalk enhancements and a new pedestrian bridge along Huie Road in Lake City, Georgia. A central feature of the development is a pedestrian bridge spanning 90 feet over Jester’s Creek, which is supported by reinforced concrete abutments.The project scope necessitated a detailed survey of Land Lots 145, 146, 175, and 176 within the 12th Land District to establish property boundaries and identify existing environmental constraints. The design process integrated comprehensive site analysis, including the mapping of critical utilities such as sanitary sewer, gas, and water lines, and the identification of flood zone areas to ensure regulatory compliance. The engineering documents provide essential grading and drainage plans alongside bridge profiles, with a focus on creating a safe and accessible pedestrian corridor. Technical specifications for the survey included the use of advanced robotic total stations and GNSS receivers to achieve high-precision data for the structural and civil engineering requirements of the site.

Role

Structural Engineer/Designer

Services Provided

The scope of services included the preparation of structural calculations for the proposed pedestrian bridge in accordance with the applicable U.S. standards, including the AASHTO LRFD Guide Specifications for the Design of Pedestrian Bridges and relevant Georgia DOT supplements. Structural analyses considered pedestrian live loads, wind, seismic, temperature, and railing loads to evaluate the overall performance and stability of the structure. The work involved the structural verification of all bridge components, including main girders or trusses, stringers, deck or slab systems, railing posts, bearings, and connection plates to confirm compliance with design requirements. Services also included the complete design of steel connections, such as beam-to-beam, beam-to-post, bracing, and bearing connections, to ensure adequate load transfer and structural integrity. In addition, the foundation and substructure systems, including spread footings and reinforced concrete piers on both sides of the bridge, were designed based on available geotechnical recommendations and applicable design criteria.
