Without much fanfare, Venice's fourth bridge over the Grand Canal is opening this week. The work of the noted Spanish architect Santiago Calatrava, the construction, which has gone on for years and been over budget, has been criticized as unnecessary, not accessible to the disabled, and not fitting in with the rest of Venice.
I haven't seen it, but know that it connects the bus terminal at Piazzale Roma to an area adjoining the train station. It is not immediately apparent why people will want to go from the bus terminal to the train station. Unless further construction is planned down the road (or down the calle or canal) making it more worthwhile. A mystery for now, like so many Italian things.
