Dalreoch Bridge

Dalreoch Bridge is a single arched bridge that crosses the River Earn. It was constructed between 1931 and 1932 for the Ministry of Transport and carries an unclassified road, which was formerly the A9, just west of Chapelbank.

The bridge is made of reinforced concrete and features four arched ribs that support a series of square plan concrete columns. The two ribs directly under the roadway are thicker than the ribs on the sides. Each side of the bridge has spandrels with three openings, and there are flood-relief tunnels in the abutments. The parapets alongside the flat carriageway and footway are intricately designed in an art deco style.

Historically, this bridge was built to replace the 18th century Old Dalreoch Bridge, which was located a short distance downstream and was demolished in the late 1960s. The new bridge was intended to accommodate the A9 route connecting Stirling and Perth, providing a wider structure capable of handling two carriageways and a higher volume of traffic.

Construction faced challenges due to severe flooding of the River Earn in June, November, and December of 1931. The bridge was eventually opened to traffic in September or October of 1932. In the 1980s, when the A9 was upgraded to a dual carriageway, the road was realigned at Dalreoch, and a new bridge was built downstream, leaving the Dalreoch Bridge to carry an unclassified road.
