A drawbridge, is not only a practical way to let ships enter the lagoon from the sea but provides a major source of entertainment as the “big” boats enter or leave st. martin. time your cocktail or meal at the st. maarten yacht club with the bridge openings and share the drama of speed ii without the trauma. Another attraction is the brand new Causeway Swing Bridge in St Maarten Causeway Bridge. The bridge was just installed to connect the French and Dutch sides of the island along the border that divides the two countries through the Lagoon. Over a year to complete, and the new bridge just opened two years ago!
