Spectators attending tomorrow's final day of the Ryder Cup at the K Club are urged not to use the Park and Ride facility at Weston Aerodrome, Lucan.
Heavy rain has made the underfoot surface at Weston unsafe and members of the public wishing to use the facility tomorrow will be facilitated at Punchestown racecourse instead.
"We would be extremely grateful to all members of the public if they could co-operate with this request to use the facilities at Punchestown Racecourse," a Ryder Cup spokesman said.
"The continuing heavy rain has reduced the parking opportunities at Weston Aerodrome and a much safer and comfortable option exists at Punchestown Racecourse with its hardcore walkways.
"Any private coach that arrives at Weston Aerodrome will be redirected to Punchestown Racecourse."
The South Park and Ride at Palmerstown House, Johnstown, remains shut and travelling supporters must continue to use Punchestown Racecourse.
