The Sandy Ground bridge at Marigot on the French side of St. Martin will be open their normal hours.
Here's an excerpt from an article in the local paper, May 30th:
SIMPSON BAY--The lift deck, bearings and struts of the Simpson Bay bridge will be repaired starting Monday, June 9. At least one bridge opening every other day will occur until June 16 when all openings will cease for a week when new struts to support the bridge balancing arms will be installed.
The bridge will remain closed until Sunday, June 22. After this, the once every other day opening will resume until the work is completed on June 28. The days and opening hours are dependent on the stage of the repairs and will be announced soon.
