|Route outline (key)|
The M50, forming three-quarters of a ring road around Dublin, is one of the most important and significant motorways in the Republic of Ireland. The most recent development has been construction of the Dublin Port Tunnel; now only the south east of the city area, most notably the port at Dún Laoghaire, has not been bypassed.
The M50 starts at Dublin Port, not far from the city centre, it immediately has toll booths for the Dublin Port Tunnel, which takes us to near the edge of the urban area. Having emerged from under the ground, and merged with the N1, it TOTSOs with the M1 near Dublin Airport and joins the C road - so called because of its shape. We skirt around the edge of Dublin's urban area, crossing the Liffey on a tolled bridge. For many years, the bridge had toll gates, which themselves caused congestion, however, in the mid-2010s free flow "video" tolling was introduced on the route, requiring drivers to either create a free account and top up from card, or to pay afterwards via internet, telephone, or in local shops. The removal of barriers has reduced congestion considerably travelling around Dublin.
Continuing south, we pass more of Dublin's radial routes before eventually reaching M11 near Bray. Unlike at the M1 to the north, here the M50 flows freely onto the M11 to head south further into County Wicklow, with the northbound M11 traffic itself TOTSOing on approach to Dublin.
The Section from J3 to J2 was formerly the M1.
A massive widening project was undertaken between 2008 and 2010 - during which all the junctions with primary routes were changed from roundabout interchanges to complex, free-flowing (except the N3 Junction) interchanges. SInce then the bulk of the road, other than the port tunnel section, has been operated by M50concession.
