Summary

The Sheriff Street Lifting Bridge is a single-span rolling-lift bascule bridge of 1939–41 that carries Upper Sheriff Street across the Royal Canal at Spencer Dock in Dublin 1.[1][8] It is recorded by the National Inventory of Architectural Heritage (Reg. No. 50010016) with a Regional rating, but it does not appear on Dublin City Council's statutory Record of Protected Structures.[2][10] The bridge is now fixed and no longer operates as a lifting structure, and Dublin City Council has progressed remedial/restoration works for it under the "Spencer Bridge" project.[1] This note assesses its heritage status and any vacancy/dereliction signals.

Identification

The structure is consistently identified across sources as the Sheriff Street Lifting Bridge, also referred to as "Spencer Bridge" in the context of recent restoration works.[1][2] (High)
Identification ambiguity to flag: "Spencer Bridge" / "Spencer Dock" naming overlaps with the modern Spencer Dock Bridge (a 2009 road bridge over the Royal Canal nearby) and with the adjacent Scherzer rolling-lift bridges at North Wall Quay/Spencer Dock. These are distinct structures and should not be conflated with this lifting bridge. (Medium)
The workspace record gives Description "Lifting Bridge", Street "Sheriff Street", Post Code "Dublin 01", which matches the NIAH-recorded structure at Spencer Dock. (High)
