Tel Aviv is Planning for a New Freeway Cap Park

"Tel Aviv city officials have given initial approval to an estimated $500-million plan to add a 60-acre roof park over the central segment of the Ayalon Freeway, the busiest transportation artery and densest infrastructure corridor in Israel.

The plan calls for covering a 2-kilometer-long by 100-meter-wide section with a grassy roof, with traffic flowing through a tunnel underneath."
