PARIS (AP) — For the first time in over a century, Parisians and tourists will be able to take a refreshing dip in the River Seine. The long-polluted waterway is finally opening up as a summertime swim spot following a 1.4 billion euro ($1.5 billion) cleanup project that made it suitable for Olympic competitions last year. Three new swimming sites on the Paris riverbank will open on Saturday — one close to Paris’ Notre Dame Cathedral, another near the Eiffel Tower and a third in eastern Paris.
