Documentation compiled after 1968.

Notes
Survey number HAER WY-70
Building/structure dates: 1913 initial construction
Significance: The Irigary Bridge has a span of 200 feet and, therefore, is the longest clear span of any county bridge still in use in the State. It is exceeded in simple span length by only one highway truss and one abandoned roadway truss, both 250 feet in length. As one of only two pin connected Pennsylvania through trusses in the survey, it is one of the most important bridges in Wyoming.
