City Junction is the name of junction 1 of the M50 motorway, positioned close to Dublin city centre. It opened in 2006 as part of the Dublin Port Tunnel, which is immediately to the north west.

The junction serves Terminals 1 and 2 of Dublin Port. It features a large flyover, but with traffic signals controlling the merge onto East Wall Road. Traffic leaving the Port is given the option of taking the motorways out of the city, or the R131 into the city.

Prior to the construction of the tunnel, the main exit from the Port was Tolka Quay Road. This moved on to Promenade Road so that right turns could be made via the new underpass. Bond Road was already in place to provide access to Eastpoint Business Park, and part of this road became one of the new sliproads, as well as the approach to the junction along East Wall Road.

As the Port Tunnel is tolled, traffic is given the choice of joining the M50 to use the tunnel, or using East Wall Road to go around it.

This is a rare example of a motorway junction built entirely on land reclaimed from the sea. East Wall Road is the original shoreline, before the port expanded.
