Business owners in Ipswich have revealed that the installation of the portal has sparked delivery chaos on the Cornhill.
The portal, which was unveiled in October, is set up as a window on the Cornhill to connect Ipswich with countries around the world.
However, the installation of the portal, as well as new bollards, has led to delivery vehicles finding it trickier to navigate the area.
One business owner said: "Now they've installed the portal and these bollards, it's a tight squeeze to get vehicles through the Cornhill.
"Especially on market days the gap between the stalls and the portal makes it difficult."
Another business owner added that he has seen delivery vehicles get past the portal but agreed that the positioning of the portal could have been better to prevent delivery issues.
Ipswich Borough Council declined to comment in relation to the concerns.
The portal is part of Ipswich Borough Council's wider 'Digital Ipswich' £2.34million project from the government's Towns Fund.
The cash was ringfenced and only able to be spent on certain projects in the town centre.
Councillor Neil MacDonald, leader of Ipswich Borough Council, had previously said was delighted to unveil the portal - stating it will help Ipswich "connect" with other cultures in different countries.
He said: "I’m delighted that we’re the first place in the UK to welcome this innovative sculpture, which has been hugely successful elsewhere.
"The portal brings people together from other countries as a window into our vibrant town centre, so we can see other cultures and connect with families and other people across the globe.
"We can’t wait to see everyone and I know residents will be curious to peek into other countries for free, without having to travel from their home town.”
