The London Bridge (Irish: Droichead Londan) is a bridge over the River Dodder in Dublin, Ireland.

The current bridge was opened in 1857[1] with an unknown engineer designing the structure.

A previous bridge was built at some point between 1798 and 1837 based on historical maps of Dublin.

The bridge connects Bath Avenue to Londonbridge Road (Irish: Bóthar Dhroichead Londan) on the R111 road.

Traffic across the bridge is limited to one lane by traffic lights at each end.
