Source-derived summary

Llandinam Bridge (Welsh: Pont Llandinam) is a single-arch cast-iron Grade II*-listed bridge located in Llandinam, Powys, Wales. Constructed in 1846, it was the first cast-iron bridge in the county of Montgomeryshire, and was designed by Thomas Penson to replace an earlier timber bridge.

Description

Llandinam Bridge is located in the northern section of the village of Llandinam and is near the main A470 road as well as its byroad west over the River Severn. The bridge is made of cast iron and consists of a single segmental arch which is 27.4 metres (90 ft) long and rises by 2.7 metres (8.9 ft). It consists of three curved cast-iron ribs which are 685 millimetres (68.5 cm) deep and 63 millimetres (6.3 cm) wide and are made from five X-shaped lattice panels. The bridge's spandrels are of an X-shaped pattern which are stiffened and tied laterally by cruciform and circular cross-members and is similar in design to the Mythe Bridge in Tewkesbury, Gloucestershire.

Its surface is flat and falls towards the west and is 3.4 metres (11 ft) wide. 1.1 metres (3.6 ft)-high horizontal girders run along both sides of the bridge and the girders on the west side date from 1846. Llandinham Bridge has ashlar masonry abutments which are sloped at 30 degrees from the point of connection with the bridge's arches and were built by Gellidywyll-based designer Edward Jones. A statue of industrialist David Davies is located at the east end of the bridge adjacent to the A470 road who laid the foundations of the bridge.

Editorial analysis

Why this record matters

The phrase “bridge in United Kingdom” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Apr 5, 2025. The linked authority identifier is Q17739033. Authority coordinates are 52.486, -3.437. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1846.

Critical limits

Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
