A major security operation was swinging into place on Wednesday as European ministers arrived for a meeting.
EU ministers are meeting at Gosforth Park, Newcastle, over three days.
Police said months of planning has gone into setting up the security operation which will involve specialist units, including firearms.
Northumbria Police said they have worked to achieve a balance between the security requirements and needs of businesses and residents in the area.
Assistant Chief Constable Kevin Mathieson said: "After months of planning, the policing operation has gathered pace over recent days and anyone passing Gosforth Park can now clearly see how the preparations for the meeting are in place.
"An event of this nature involves tight security but we have been working hard along with our partner agencies to balance the necessary security requirements with the needs of residents and businesses in the area."
The force said there would be a large number of officers policing the event but there would be sufficient officers across the rest of its area.
Police said as the event is being held on private land, traffic disruption should be minimal.
A secure area has been set up around the site and only people carrying authorised passes will be allowed access.
There is no specific intelligence to suggest the event will be targeted by terrorists, but police are urging people to be alert.
