Massive Tidal Flows

Pedestrian bridge closed November 2011 - April 2012. Can see tidal current from park, but not stand over it.

We tried to visit this during a full moon at 12 PM.

There is no parking on the south end. And there isn't easy access to the bridge going northbound. You can get off, and park your car in the park, except the park closes at 8PM. And you need to walk on in the one land road going the opposite direction to get to the bridge. Southbound, getting to the park can be a challenge, as the direct exit to the Park no longer exists.

Yes, "massive tidal flows" sounds kind of boring - but it's NOT! Take my word for it.. this is neat. I haven't been since 1996 but since there is still a moon I can imagine that the tides are still very extreme.

You can actually see the water rushing in and out from above! Here's what you do.. Park your car at Hilton State Park (located off Route 4/Spalding Turnpike). Beside the new bridge there is an older bridge which is still standing (but closed to vehicle traffic). Walk to the center of the bridge above a support pillar (with edges shaped like a ship's bow - for good reason) and you'll see and hear the water literally RUSHING past during the incoming and outgoing tides. If you stand and stare down at the support structure long enough you'll actually get the sensation that you are moving.

Check the local tide tables before you plan you're trip so you can be sure to see this is a really good day. This is the second most extreme tidal flow *in the world* next to the Bay of Fundy in Canada (which totally empties at times).

Great ... where can we buy "Massive Tidal Flow" t-shirts for our friends?
