construction
Quick Summary
A trestle is a framework used to support a structure, such as a bridge. Trestlework refers to a system of connected trestles that support something, like a railroad bridge. In construction, trestle supports can be used for large areas where the working height doesn't need frequent adjustment, similar to how carpenters use sawhorses. These specially designed trestles can be adjusted to provide working heights ranging from 7 to 18 feet.123
