The route of the causeway is the same now as it was when contructed. It involves four separate open space water crossings, two of which are on either side of Blakeley Island.
The photo here is the bridge over the westernmost outlet of the Tensaw which merges with the Spanish River from the Mobile River. All of the spans are fixed.
To my knowledge, the only crossing with a lift span was over the Mobile River proper.
The spans over the easternmost two outlets of the Tensaw near
Spanish Fort are not shown, suggesting that they were not Parker through truss.
