New arrangements for the flow of northbound Cork city centre traffic will come into effect today.
Cork City Council say the changes are part of an initiative to prioritise public transport and improve accessibility.
Traffic coming from the South Link road wishing to travel towards Blackpool and the northside of the city will now have to travel through Custom House Street, Penrose Quay, St Patrick's Quay, Camden Place and turn north onto the Link Road.
Two westbound lanes will continue to be provided to cater for this route.
From Parnell Place, northbound traffic will turn right by the Bus Station, turn left onto a new northbound lane on Brian Boru Bridge, turn left on St Patrick's Quay and continue onto Camden Quay and the North Link Road.
Access for those wishing to access the train station, the lower Glanmire Road and east Cork will continue via Ship Street.
Summerhill North will now be accessed via a new northbound lane on Brian Boru Street.
The Middle Parish, the west of the City and North Gate Bridge continue to be accessed via Merchant's Quay and Lavitt's Quay.
