Palmerstown Interchange is junction 1 of the N4 and junction 7 of the M50.

The junction opened as a roundabout interchange in 1990, as part of the West-Link Bridge. With the N4 gaining bypasses of Palmerstown and Chapelizod, this junction became the main route for accessing Dublin from the south-west, doing the work of both the N4 and the N7.

Further upgrades to the N4 west of here caused traffic levels to rise further, and the opening of the Liffey Valley shopping centre tipped things over the edge. The junction was eventually given a comprehensive upgrade in 2008.

The N4 east of here was downgraded to R148 in 2012.

Despite the new road layout, the junction does still suffer from congestion, primarily due to vehicles braking for the narrow slip roads.
