Why is there no bridge to Port Aransas TX?
According to this old link ( www.window.state.tx.us/tpr/btm/btmtr/tr13.html ) with 1991 figures, it cost $1.2 million per year to operate the ferry and it would cost over $88 million to build a bridge. The document does not say that it is technically impossible to build a bridge, but it does mention that there would be a minimum height requirement due to the tall ship traffic.
