Seoul Plans Underground Road Highway Posted on Aug 6, 2009, 7:02AM by report411 794 Views, 0 comments, Email It From 2017, Seoulites will be able to drive on underground roads free of traffic jams, but the safety of the 60-meter-deep roadways is being called into question. There will be six underground highways - three north-to-south and three east-to-west. The roads will form a lattice pattern and the intersections will be connected to form two circular roads.
