In Istanbul, major public transit projects are back under way after years of paralysis. The problem wasn't a lack of financing, but the layer upon layer of ancient artifacts that turned up every time the earthmovers started their work.
The excavation began eight years ago on projects intended to ease Istanbul's notoriously clogged traffic.
The job included building a tunnel under the Bosphorus Strait and linking it to a rail and subway network. When the dig was stopped several years ago, eyes rolled and shoulders shrugged.
