When my wife and I were attempting to get down Ty Gwyn road on Easter Monday, we got trapped just outside the box junction, by traffic coming up the road leaving absolutely no gap, but the Tram loomed behind us and began hooting at us to get out of the way.
The only possible escape route was down Old Road, but I wouldn't do that.
It was chaos, and it is getting worse... but it is entirely avoidable by simply stopping the parking on the double yellows.
