1935-ERECTION-PLAN.pdf

This is a set of detailed engineering drawings from 1935 showing the erection plans for the Cape Cod Railroad Bridge, a vertical lift railway bridge at Buzzards Bay, Massachusetts. The drawings consist of 22 detailed engineering sheets that provide comprehensive construction and assembly information for different components of the bridge structure.

The plans include specifications for the main counterweight boxes, north and south towers, tower spans, machinery houses, track layouts, tie arrangements, rope systems, and reinforced concrete floors. Key components detailed in the drawings include the tower structures rising 257 feet tall, a 544-foot main lift span, 128-foot approach spans, guide roller adjustments, spires for the machinery houses, and various structural sections showing assembly details. The drawings provide precise measurements, cross-sections, elevation views, and assembly instructions that were used to construct this bolted and riveted steel through-truss bridge designed to lift vertically to allow marine vessel passage while accommodating rail traffic across the Cape Cod Canal.
