The Day Covered Bridge was built in 1875 utilizing the Queenpost Truss.  The builder is unknown. The structure crosses Short Creek in Washington County, Pennsylvania.

The bridge, owned and maintained by the county, is in good condition and open to vehicle traffic.

This is another typical Washington County Covered Bridge.  Day Covered Bridge is covered with vertical plank siding on both the sides and portals and has a sheet metal gable roof, it also has a plain, box-like appearance that is painted barn red inside and out.  The bridge also has a deck of crosswise planking and two rectangular windows on each side, as well as the typical eave openings. This bridge of Queenpost truss design rests on the stone and mortar abutments reinforced with concrete and one abutment that appears to be all concrete. It has wing walls on both ends, three of which are stone and mortar, and the fourth concrete.

Noteworthy, the Day Bridge was closed between 1999 and 2003 when inspectors found it so deteriorated that it could not support three tons a state requirement for bridges. While a temporary bypass was utilized, renovation began in December 2002, involving the installation of steel support beams, a new roof, flooring, and sidewalls. The Day Bridge reopened in June 2003.

Of the 1,500 covered bridges that once stood in the state of Pennsylvania, as of 2019, approximately 200 remain.
