Erection of the Leas Highway Bridge near St. Joseph, Ill.
An 1903 undergraduate civil engineering thesis by Wayne Edison Burkhalter at the University of Illinois, documenting the construction of a highway bridge over the Salt Fork near St. Joseph, Illinois, for faculty examiners. Hand-drawn truss diagrams carry inked dimension lines, panel-point circles and lettered member labels, alongside a faded photograph of the site; useful for line-drawing structural geometry and drafted annotation.
