Coming in the western road and down the dyke you're funneled into a single lane that snakes along Prospect Row and Bachelors Quay. You can go left over NG bridge but that just brings you up Shandon Street and is pretty unsuitable for heavy traffic. Alternatively it's on up past the bridewell and OpraHouse Quay over CR Bridge and eventually up into the North inner-ring road which is a dose. Traffic from say the Kingsley in the West to Silversprings in the East could take you anything from half an hour to an hour using the North Ring Road.
In fact, if you use google maps the suggested route from the Kingsley to Silversprings is to use the south ring and come back in from the dunkettle roundabout - that's how much of a mess travelling West-East on the North Ring is!
