The Merrion Gates (Irish: Geataí Mhuirfean) is a railway level crossing in Sandymount, Dublin, where the DART and Dublin–Rosslare railway line crosses Strand Road near its junction with Merrion Road. It is a major traffic bottleneck, which also restricts the possible frequency of railway traffic.
There is access on foot to Sandymount Strand just to the east of the railway crossing.
Merrion railway station opened in 1835 and closed in 1935. Current neighbouring stations are Sydney Parade to the north and Booterstown to the south.
In October 2016, the National Transport Authority unveiled a proposal to close the Merrion Gates by diverting motor traffic onto a new road bridge over the railway some 250 metres to the north, and pedestrian and cycle traffic through a new tunnel under the current crossing.
