Att D_BR08306 Plan View Sheet.pdf

These engineering drawings are technical plan sheets for the Youngs Bay Bridge project, prepared by the Oregon State Highway Department's Bridge Division. The documents detail multiple plan alternatives (labeled A through P) for bridge spans, showing intricate structural engineering specifications including beam placements, elevation measurements, roadway dimensions, and various technical details across 12 detailed plan sheets. The drawings include specific plan spans ranging from 1-314 to 45-47-48, with precise measurements noted along E roadway and incorporating elements like conduit expansions, junction boxes, traffic gates, and signal light post details.

The technical drawings provide comprehensive engineering specifications for bridge construction, featuring multiple alternative design configurations. Notable elements include detailed measurements for beam placements (Beam O, Beam W, etc.), elevation transitions, roadway alignments, and specialized infrastructure components such as traffic gates, draw bridge signage, and rail crossing details. The plans incorporate technical annotations for expansion joint filters, electrical conduit layouts, and structural positioning, suggesting a complex multi-span bridge design with significant engineering complexity and precise structural engineering requirements.
