Commuters travelling through the M50's Red Cow roundabout in Dublin face a new traffic layout from today.
New lanes have been opened for N7/Naas Road inbound traffic heading to the city, Luas and M50.
Motorists need to follow the signs to make sure they are in the correct lane as they approach the interchange.
Citybound traffic on Monastery Lane will no longer have to stop at traffic lights. Drivers can now use a new free flow lane over a bridge.
Monastery Road traffic heading to the M50 will also be directed onto a new free flow over a bridge.
However, M50 northbound traffic will have to head south to Junction 10 Ballymount and then U-turn, until the new northbound free flow slip road is opened.
