The M50 NB to N4 W slip is now open. Quite a steep angle compared to what we're used to on the M50. Slip opened Thursday 28.06.2007.

Taken 02.06.2007 facing west, the bridge for the new M50 NB to N4 EB slip is taking shape

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.

Taken 02.06.2007. Note the bridge for the M50 NB to N4 EB slip under construction to the right. There has been quite a bit of progress in the month since this was taken.

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.

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.

Minor roads are bridged. The only intersection is the roundabout 7km from the southern end.

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.

The queue for the M50 junction and associated works starts quite a distance back. This view is facing west (outbound from the city).

This junction is unusual on the N4, being an S2 section with grade separation.

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.

This roundabout junction with the N17 (Galway - Sligo road) marks the southern limit of the Collooney bypass, a D2 upgrade which has recently been extended all the way into Sligo town itself.

Junction for the N59 on the N4 Collooney bypass. Apart from a couple of roundabouts at the southern end, the Collooney bypass is grade-separated.

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.

This is the recently-completed McNead's Bridge to Hill of Down section of the N4, which ties the toll motorway into the older dual carriageway section between Hill of Down and the Mullingar bypass. Note the New Jersey barrier down the central reservation.

The first junction on the Mullingar bypass is J9. J10 and J11 are also part of this stretch of road.
