Taken 02.06.2007, showing progress on the M50 northbound to N4 Eastbound and Westbound slips. N4 mainline westbound is on the left. It looks like soon the footbridge that these pics were taken from is going to have to be demolished and replaced with a wider structure.

Facing east, taken from the footbridge just visible in the extreme top-right of http://www.m50.ie/pages/n4-after.htm -- you can see the three eastbound carriageways taking shape here. Note the gantry foundation to the left of the blue car in the leftmost slip.

M50 J7 Lucan exit

This is the N4 facing East. This junction is no longer a full grade-separated roundabout. If North is at 12 o'clock, the section between 8 and 10 o'clock has been removed, so inbound traffic now only meets this one set of traffic lights rather than the former two sets.

M50 NB traffic merges in on the extreme left. This merging lane has recently been extended under the pedestrian bridge this photo was taken from. Previously the merge was more sudden, as the left-hand lane had to avoid the bridge.

Boyle was bypassed in the 1990s with this S2 road. North of the town and extended 2+1 scheme allows cars to overtake slower traffic through the hills. Donegal appears as a destination for the first time here.

The dual carriageway section south of Sligo has recently been extended by the opening of the Sligo Inner Relief Route (IRR). Until last year, traffic on the N4 was dumped off the D2 onto suburban roads on the outskirts of Sligo. Now traffic can continue straight ahead.
