The live video link between Dublin city centre and New York’s Flatiron district has come to an end.
However, the Dublin Portal is to stay in place and is now being linked with a new US city, Philadelphia.
Introduced five months ago, the portal was due to operate until the end of October, but that has been extended until the end of next January.
It is located between North Earl Street and O’Connell Street.
Its operating hours have been extended and run from 8am to 8pm.
The portal will now link to JFK Plaza Park, which is also known as Love Park, in Philadelphia and will continue to alternate between there and two other portals in Vilnius, Lithuania and Lublin in Poland.
Further locations for live links are due to be announced in the coming weeks.
Within days of the portal being launched in Dublin last May, Dublin City Council had to change the way it was operating due to "inappropriate behaviour" by users in both Dublin and New York.
This included the exposure of body parts and rude gestures.
Officials said the the vast majority of interactions have been positive with at least 435,000 visitors to date and increased footfall in the north inner city.
