Just need to be aware that there is a sliding gate on that road just off the north edge of the construction area, has been there for as long as we have been going to SXM. Open during the day but closes somewhere around 7:30+/- PM.
If/when the normal route that skirts the pond gets in bad shape it's not a bad alternative for getting up to the main road. Having done so several times our latest trip it added about 5 minutes to our drive time to Oyster Pond.
