Punters driving down to the Oxegen festival from Dublin are being warned that traffic is still heavy on the N7 Naas Road outbound from the Red Cow Interchange to Newlands Cross.
All lanes have re-opened outbound between Citywest and Rathcoole following earlier flooding.
AA Roadwatch says delays are easing on approach.
As a result of the delays on the N7, the M50 is slow exiting both northbound and southbound at the Red Cow.
Dublin Bus is reporting a journey time of one hour and 25 minutes from Dublin City to the festival site. The usual travel time is one hour.
