Overview
Sir Thomas’ Bridge carries a minor road over the River Suir a few kilometres east of Clonmel, at the point where the river divides County Tipperary on the north bank from County Waterford on the south. Locals also call it Two Mile Bridge. It’s a five-arch humpback in rubble stone, still in everyday use and recognised as an Historic Engineering Work (HEW No. 3238) in Trinity College Dublin’s national heritage database. Most visitors come across it not for the bridge itself but because it’s a marker on the Suir Blueway – though the stonework rewards a proper look if you stop.
How old is it, really
The dates don’t quite agree, and it’s worth knowing which you’re being told. Local tradition credits Sir Thomas Osborne with building the bridge in 1690 to link his lands on either side of the Suir, and several sources repeat that. The official Buildings of Ireland survey, on the other hand, dates the structure to around 1740. Either way, it’s an early bridge, and the Osborne family kept a toll gate here until the middle of the 19th century, when crossing the river still meant paying for the privilege.
The bridge sits in the townland of Tikincor Lower, whose Irish name refers to a house at the head of the weir, and near the site of the old Tickincor Castle that the Osbornes acquired.
The stonework
The survey detail is the interesting part. Five segmental arches rest on triangular cut-stone cutwaters that split the current and reduce scour. The voussoirs are squared with chamfered reveals, and one arch carries a decorative scroll keystone – a small flourish on an otherwise working structure. A single-arch pedestrian underpass sits on the north side. The rubble walls were repointed with cement mortar during conservation work around 1990, when cast-iron tie plates were added to hold the arches.
One honest caveat: the bridge and the adjoining Blueway have a history of being closed for repairs – emergency work in 2021, and resurfacing and widening in later autumn-to-winter seasons. It’s worth a quick check of the Suir Blueway’s updates before you build a day around crossing here. The low-lying ground is also prone to flooding; the river came up over the approaches in the Clonmel floods of January 2016.
Walking the Blueway
The bridge is best taken in as part of a walk or cycle. The Suir Blueway, launched in May 2019, runs 21 km between Clonmel and Carrick-on-Suir along a flat, well-surfaced path, easy going for families and casual cyclists. From the bridge you can head downstream (east) toward Kilsheelan and on to Carrick-on-Suir, or upstream the short distance into Clonmel. The slow Suir here is good heron and kingfisher water, and early morning is the quiet time to see it.
For photographs, the humpback profile stands out against the sky in low morning or evening light, and the north-bank underpass frames a clean shot downstream. Keep well back from the edge after heavy rain, when the towpath turns muddy.
A small lay-by nearby gives space to park and walk the bridge and towpath on foot. Note that the road carries light local traffic, so pedestrians and cyclists should take care on the deck.
Nearby
Clonmel is a short drive upstream, with cafés, independent shops and the medieval town centre. The bridge itself is a half-hour stop; paired with a stretch of the Blueway towpath it makes an easy afternoon.
