We have driven by many times and see all kinds of trucks with trailers off to the east of the highway, occasionally a larger RV. The area does not look really big rig friendly, but walk in, or go slow to pick a route.
Last month there was road construction going on and limited and controlled access to the highway. They are working on the south bound bridge. I think that once in, you have to exit north bound, cross the river bridge and make your u-turn to head south.
