Gifford Covered Bridge
}}
The Gifford Covered Bridge, also called the C.K. Smith Covered Bridge, is a wooden covered bridge that crosses the Second Branch of the White River in Randolph, Vermont on Hyde Road. It was listed on the National Register of Historic Places in 1974.〔
The bridge is of King post truss design by an unknown builder. This bridge is one of only two covered bridges in Vermont (the other being the nearby Braley Covered Bridge) in which the king-post truss reaches only half the height of the bridge. The reason for this is that the bridge was most likely a wooden boxed pony truss bridge when first built in 1904. The trusses would have most likely been covered by planking to protect them, rather being left open. See the article on Mean's Ford Bridge in Pennsylvania at (BridgeHunter.com ) for an example of this rare type of bridge.
==Recent history==
Circa 1955 the bridge deck was reinforced with steel -beams ''above'' the roadway which are in turn tied to -beams below. This being an unusual way of strengthening a covered bridge. In 2001, extensive repairs were made to the bridge, including raising it up from the river to help prevent flood waters from reaching the deck. Despite the repairs, a relatively low weight limit of 3 tons remains on the bridge. There is evidence that the weight limit is forcing heavy vehicles to ford the shallow river next to the bridge.〔Evans, Benjamin and June. ''New England's Covered Bridges''.
