I'm surprised they're not talking about a third bridge in the middle, carrying a direct freeway connection between MA-25 on the mainland and US-6 on the Cape. It's an obvious route, and it would connect most of the Cape (everything except the Falmouth area) to most of the rest of the world (everything except the Boston area). And it would reduce the cost of replacing the other two bridges, since four travel lanes would probably be enough for the reduced traffic on them.
If this were to happen, I see the following happening as well:
US-6 would be rerouted onto the new bridge, connecting MA-25 in Plymouth with the Mid-Cape Highway in Sandwich (making US-6 shorter by about 2-3 miles or so).
MA-3 would be extended to Sandwich taking over the former US-6, ending at the new exit (making MA-3 longer by about 2-3 miles as well).
No direct connection from South MA-3 to West US-6 (Must go via South MA-3A [former US-6 along the north end of the Canal] or West MA-6A [Sandwich Rd.])
No direct connection from West MA-25 to East US-6 (Must go via same connectors noted above)
US-6 would be multiplexed with MA-25 from the new exit to current Exit 2.
And frankly, by that point, why even have the MA-25 designation at all? Just have MA-28 take it over and multiplex a bit on I-495 to meet up with its current routing.
