Police in the North, backed by the British army, are preparing the annual security operation for the annual Drumcree standoff with members of the Orange Order in Portadown, Co Armagh.
However, the operation is to be low-level compared to previous years, reflecting optimism the parade will pass off peacefully.
Superintendent Alan McCrum, head of operations in Craigavon District Command Unit, said police took the decision after significant engagement with local groups and individuals.
He said the move was in response to last year's generally peaceful marching season, and was part of an ongoing de-escalation over the past three years.
"The safety of marchers and protesters who act within the law, the safety of the residents of the Garvaghy Road and of the broader community remains a priority for us," he said.
"We remain optimistic. We have been involved in discussions with a range of local bodies and we are confident that the reduced level of physical barriers will be welcomed.
The British and Irish governments are hoping that the parade will conclude with no major difficulties, thereby increasing prospects of a peaceful summer in the North.
Portadown Orangemen and the Garvaghy Road Residents' Coalition have urged that the 10th successive Drumcree Sunday should pass off peacefully both in Portadown and elsewhere in Northern Ireland.
Orangemen are again banned by the Parades Commission from marching down the nationalist Garvaghy Road.
Spokesmen for the Orangemen and the Garvaghy residents said they too were expecting a peaceful day tomorrow. Mr David Jones, press officer of the Portadown District, said Orangemen should act with dignity.
The Portadown District is expected to again make its outward march from the centre of Portadown for a Battle of the Somme commemoration service at Drumcree church at 11.30 a.m..
At around 1 p.m., the Orangemen, led by the district's deputy master, Mr David Burrows, would march to the barricade, seeking to make its return journey by the Garvaghy Road. When this permission is refused by police, in line with the decision of the Parades Commission, the Orangemen will hand over a letter of protest.
They will also observe a minute's silence in memory of Harold Gracey, the former district master of the Portadown Orange Order who died earlier this year.
