Ohio Department of Transportation (ODOT) | Various District 12 Bridge Inspection Services
Split by the Cuyahoga River, the City of Cleveland is deeply dependent on bridges. Connecting the east and west sides of the city, both high, fixed span and lower-level moveable bridges are critical to the movement of people and freight throughout the region. To ensure the structural health/integrity of these critical crossings, Ohio Department of Transportation (ODOT) requires annual routine and biennial fracture critical bridge inspections for all fracture critical (FC) bridges. As part of a team, Patrick inspected three high-level bridge crossings, including the Main Avenue Bridge (circa 1938), Hope Memorial Bridge (formerly Lorain Carnegie Bridge, circa 1932), and the Veterans Memorial Bridge (formerly Detroit Superior Bridge, circa 1918). Patrick’s bridge inspection experts inspected all fracture critical members within arm’s-length reach using a combination of ladders, self-propelled aerial lifts, and Snoopers™. Patrick authored the 2020 Main Avenue annual routine inspection report including revising the ODOT Bridge Inspection Report by utilizing the online ODOT AssetWise (AWARI) inventory and appraisal data collection system.
