A truck carrying specialist tunnel-boring equipment to the Shell refinery project at Bellanaboy in Co Mayo is still blocking the road two days after first getting stuck at the Glenamoy crossroads.
In a statement, Mayo County Council said protester activity overnight prevented lifting-equipment being brought to the site to remove the truck.
The council said it would continue to work with Shell to resolve the issue as soon as possible.
The truck got into difficulty while navigating a turn on the narrow roads.
It is understood the lorry was transporting loads of up to 150 tonnes.
