In Dublin city centre this weekend there will be restrictions to traffic on Parnell Square. The removal of a crane from a building site on the square means parking will not be permitted along Parnell Square West from 9pm tonight until the work has been completed.
One lane of traffic will be maintained along the Rotunda Hospital side of Parnell Square West throughout the day to service traffic coming from the O'Connell Street direction.
Although no serious delays are expected due to sports fixtures this weekend, local congestion is likely around the rugby matches at the Sportsground in Galway where Connacht play Llanelli, kick-off 2.30pm. Elsewhere, Munster take on Glasgow at Thomond Park in Limerick, kick-off 3.30pm.
There's also racing this weekend at Navan on Sunday and Gowan Park on Saturday - which will cause local delays.
