The name commemorates William Dargan.[2] The engineer who designed the Harcourt Street railway line, which much of the Green Line now follows.
Roughan & O’Donovan provided full engineering design services for the bridge.[3]
History
editConstruction started in October 2001.[4] The deck, 1.325 metres deep, was constructed using precast concrete shell segments that were glued and stressed together, before being filled with in-situ concrete. The 50 metre high pylon was made using reinforced concrete and 13 pairs of high-tensile steel cables.[5]
Construction was completed on 2 August 2002, where, in front of several hundred onlookers, Minister for Transport Seamus Brennan remotely tightened a stress block.[6] The entire project had an approximate cost of €11 million.[5] The first Luas passed over the bridge on 11 Feb 2004 during a test of the line.[7]
Adverts were placed in local media looking for suggestions on what to name the bridge. The final name was chosen by a committee set up by the Railway Procurement Agency. It included the Luas chief architect, Jim Quinlan, historian Briain MacAonghusa and a representative of South Dublin County Council. Proposals included; William Dargan, Stephen Roche, Canon Harrington, and Suas Luas (suas being the Irish word for "up"). The bridge was official named the William Dargan Bridge by Seamus Brennan in a public ceremony on 19 July 2004.[8] Where a ribbon was cut by Fr Dan Dargan, the great-grandson of William Dargan.[9][10]
After the death of Seamus Brennan in July 2008, Fianna Fáil councilor Gerry Horkan proposed the bridge should be renamed after him,[11] which was turned down.
