Seoul announced plans to make its urban landscape greener.
The city will expand the plaza downtown at Gwanghwamun to make a pedestrian-friendly, tree-lined walkway from Gwanghwamun to Seoul Station.
This will involve a major re-routing of traffic.
The lanes of the road on the west side of the plaza, will be closed and incorporated into the square.
The lanes on the east side, near the U.S. embassy will be expanded and made into a two-way street.
These changes will take effect on March 6th.
