Iraqi security forces removed concrete blocks Wednesday along Baghdad's Al-Nasr Square to reopen the road leading to Al-Saadoun Tunnel near Al-Tahrir Square.
After the concrete barriers were removed, workers cleaned the tunnel.
The tunnel passes under Baghdad's Tahrir Square, which has been the epicenter of the protest movement.
The Saadoun Tunnel had become an ad hoc museum for Iraq's massive anti-government protest movement.
Along its walls, young artists drew murals, portraits and graffiti that illustrate the country's tortured past and the Iraq to which they aspire.
In October of last year, tens of thousands of Iraqis — mostly young people — marched in Baghdad and cities in the south to decry government graft, unemployment and poor services.
