Agree with everything you said, except the new bridge should be a twin bore tunnel. The geotechnical risk was effectively retired by the recent water tunnel project (single bore, 15 ft dia.) That tunnel project under Dumbarton went so well that the boring machine had to wait at the end of its drive for the exit shaft to be completed.
