Engineering Analysis
A new load carrying capacity analysis of each bridge was prepared in accordance with AASHTO’s Manual for Bridge Condition Evaluation of Bridges (LFD). This included both inventory and operating ratings based on H, HS, and 3-3 truck configurations.
Hydrology and hydraulic studies were performed for roadway structures with openings less than 20 feet in width, including side drains, cross drains, inlets, and storm sewer systems.
