There were no fatalities reported following a collision between two vehicles on the Stillorgan dual carriageway earlier today.
One of the vehicles overturned while there was extensive damage to the front of the other vehicle involved.
The N11 was closed inbound at Mount Merrion Avenue and there were long delays on approach for several hours.
The upturned car blocked the inbound lane of the carriageway at Mount Merrion near the Radisson Hotel, and diversions were in place until the road was reopened just after 4pm.
