First Freeflow on N4/M50 Interchange

I have just received an email from a friend of mine with a copy of a leaflet he has given while waiting at the lights at the N4/M50 junction. It informs us that the first permanent freeflow lane at the N4/M50 junction will be opening in mid-January 2007.

N4 FreeflowThe leaflet goes on to say that:

“This slip road leading from the N4 eastbound (i.e. coming from Leixlip and the West) will allow motorists to turn left to go northbound on the M50 towards the Toll Bridge, without having to go through the lights.”

This is great but there is bad news, as the diagram shows, traffic coming from town that wants to go North on the M50 and Northbound M50 traffic that wants to go into town will have to divert through Liffey Valley.

At the minute, this has to be one of the worst stretches of road for traffic congestion because if you are travelling East on the N4 and you want to go North on the M50 you are corralled into a single lane on the bridge. To make things worse if you have EazyPass you can’t use the dedicated EazyPass lane because it’s on the opposite side of the road and you are prevented from crossing over by a series of bollards.

You can get more information on the changes that they are going to be making on the M50 website,
