IT'S been a traffic nightmare for decades - made worse during construction work over the last year - but the new flyover at Newlands Cross was finally opened to traffic yesterday.
A staggering 85,000 cars a day use the route, which often resembled Ireland's largest car park.
So to put the new flyover to the test, the Herald yesterday took a typical journey in rush hour traffic from the city centre towards Grange Castle, Co Dublin.
In recent times this trip would have taken the best part of two hours, with a back log being caused from the thousands of cars bottle-necking from the M50 motorway, the Belgarde Road and the N7 itself at the Newland's Cross junction.
Our journey started at Fitzwilliam Square, which Google Maps rather optimistically puts as a 37-minute drive to the west Dublin suburb.
Roadworks at Stephens Green slightly hampered the early stages of the trip and it took 30 minutes to reach Crumlin, and a further 20 minutes to the Red Cow.
We then reached the decisive part of the journey, which had once been the bane of the N7 traffic commute.
The flyover was by far the least congested part of the journey taking less than two mintues to get from Newland's Cross to Grange Castle.
Overall the journey took a respectable hour to complete, which only days before could have taken at least twice that long.
