Anti-far right banners will be draped from iconic bridges across the UK ahead of Donald Trump's inauguration as the next president of the United States on Friday (20 January).
The protest has been organised by the Bridges Not Walls group and is supported by the Green Party.
"[The demonstration is about] standing with communities that could be vulnerable to the election of Trump and the promises that he's made as well as taking a stand against the rise of the far right in Europe and the UK," a spokesman for the group told IBTimes UK.
London's Tower Bridge and Bristol Bridge will be just two of the landmarks included in the protest.
"As Trump takes power, we will not let the forces of fear and hate he represents stop us from helping some of the most vulnerable in our society," said Jonathan Bartley, Green co-leader.
"We're proud to be taking a stand against xenophobia, the rise of the far right and the politics of hate and division, both in the US and here in the UK."
Thousands of people are also expected to attend a women-led march in London on Saturday to coincide with Trump's first day in power.
