Reinforced concrete arch bridge. Copings, stringcourses and quoins are of ashlar masonry with the remainder of the masonry rock faced. The end of the concrete deck is exposed in elevation. Carries the A39.
References to the bridge occur as early as the 13th century. Leyland described it as a " Bridge of stone of 4 arches communely caullid Pontperlus, wher men fable the Arthur cast in his Swerd." Phelps in his History of Somerset gives an illustration of the bridge which existed before the rebuilding in 1826. From this it appears that the bridge had 2 arches, one semicircular in shape, the other apointed arch, possibly built in the 15th century. During excavations for a new bridge in 1912, the remains of second round arch were found to the South. It was regarded as C12 work. Parapet inscription: S.C.C. (Somerset County Council) "PON PERILIS" built 1912

The old bridge, the predecessor of the medieval stone bridge, was referred to in documents of 1163, but may have been pre-Conquest in origin. The excavations which located the pre-Conquest causeway north of Street also encountered heavy oak timbers which might be part of the structure of this bridge. However, a 10th century charter appears to refer to a stone bridge carrying this road (Costen, 1992).The bridge is mentioned in 1502 as Street Bridge;3
