The original bridge on the site was opened on 24th June 1986 by Ray Burke TD, Chairman of Dublin County Council. A stone was placed by the bridge to mark the opening. This bridge was a single carriageway two lane bridge, for a local road that linked Tallaght Road and Firhouse Road.
When the M50 was built through the area in the 1990s, the original bridge became the northbound exit sliproad of the Tallaght Interchange, with new bridges constructed downstream to carry the main line of the motorway and the southbound entrance sliproad.
Furthermore, a new bridge was built further downstream to carry local traffic, the Spawell Bridge.
