Hughes Covered Bridge
Why it's listed
Hughes Covered Bridge is a queenpost-truss covered bridge crossing Ten Mile Creek in Amwell Township, Washington County, Pennsylvania. It was built in 1889 and has vertical siding, a tin-covered gable roof, and four windows on each side wall. The bridge measures about 55 feet along its end posts and carries a road surface 12 feet 4 inches wide. It was once in regular use for traffic but is now no longer used and stands in a field off Interstate 79 at the Marianna exit, south of Washington. It was included in a group of covered bridges in Washington and Greene Counties. The bridges in that group are regarded as important examples of vernacular wood bridge construction, and they reflect the way local builders used wood trusses and simple local design features in rural settings. The listing is based on that group's collective importance.
Significance in brief: The nomination treats the bridge as one of the covered bridges of Washington and Greene Counties, a group regarded as important examples of vernacular wood bridge technology. The bridges are said to reflect the common use of wood-truss types in these rural counties. The bridge is listed as part of a multiple-property group rather than for individual distinction.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
