Dalreoch Bridge

Dalreoch Bridge is a single arched bridge crossing the River Earn. It was built between 1931 and 1932 for the Ministry of Transport. It carries an unclassified road, formerly the A9, across the River Earn immediately west of Chapelbank.

The bridge is constructed of reinforced concrete. Four arched ribs support a series of square plan concrete columns. The pair of ribs under the roadway are thicker than the flanking ribs. The spandrels are pierced by three openings on each side and there are flood-relief tunnels in the abutments. The parapets flanking the flat carriageway and footway are heavily detailed in art deco style.

Historical development:

The bridge was built between 1931 and 1932 to replace an 18th century bridge (Old Dalreoch Bridge), which was formerly located a short distance downstream and was demolished in the late 1960s. It was built to carry the A9 route connecting Stirling and Perth across the River Earn, replacing the narrow older bridge with a bridge capable of carrying two carriageways and a greater volume of traffic.

Construction of the bridge began in 1931 and was hampered by severe flooding of the River Earn in June 1931, and again in November and December of that year. The bridge was opened to traffic in September / October 1932. When the A9 was upgraded to dual carriageway in the 1980s, it was re-aligned at Dalreoch and a new bridge built a short distance downstream. The Dalreoch bridge now carries an unclassified road.
