Roads can be places where multiple channels meet. One of the busiest seaway roads in the US is Bolivar roads, just outside of Galveston Texas. At Bolivar Roads, the Texas City channel, the Houston Ship Channel and the Inter-coastal Waterway all intersect. So you have big ships, long barges being pushed by towboats, shrimpers, pleasure craft, and for an added bonus, the ferry between Galveston and Bolivar trudging to and fro. It is one of the busiest water crossings in the US. Freeways are pretty much like vehicle freeways, vehicles moving about freely, avoiding one another. It is not a place to anchor. Of particular importance in the Gulf of Mexico is that you are not allowed to plant oil or gas rigs in the freeway. Think of building a skyscraper in the middle of the interstate. Not a good thing.
One evening on a Gulf of Mexico crossing from Galveston to Port Aransas (9 hours by car - 42 hours by sailboat), my friend and I were on evening watch. She was at the helm, I was on watch. The moon was full. The silence was only interrupted by the lapping of the waves against the boat and the occasional and infrequent clanking of a mark. It was perhaps as quiet as you can imagine the earth being. And as I scanned the horizon, and the surface of the water, as my job on watch was to do, off our port side probably at least 5 miles away was the silhouette of a massive ship. Silently gliding parallel to us. It was a hauntingly beautiful moment, one that revealed the beauty of nature and the thankfulness of technology which would have alerted us to her presence, had she been any closer.
It was a strangely thin place.
