The earliest construction of Thomond Bridge was built near a fording point.
[1] The old medieval Thomond Bridge, of fourteen arches, sat on the same site as the current bridge,[2][3] near the 13th-century King John's Castle.
[4] The Treaty Stone was placed near to there, symbolising the end of the 1691 Siege of Limerick, during which the bridge was the site of a failed defence of Limerick City.
The current bridge, of seven arches, was built in 1836,[5] replacing the earlier structure while incorporating its pier foundations.
[6] The bridge now forms part of the R445 (formerly the N7), carrying traffic on the Northern Relief Road.
