That's what I've always assumed.
The 4-laning of 331 and the new parkway are both in motion and on their own track. I don't think it is an either/or situation. I fully expect 331 bridge will be a toll bridge, maybe both will be.
10 cents to get in to SoWal and 5 bucks to leave.
I haven't heard that there was much motion on four-laning the 331 bridge, lately.
If any of the routes of the proposed parkway do not cross the intercoastal, it wouldn't be much of a difference than the existing route.
If the parkway crossed the intercoastal, the bridge would be essential the same as the Westbay Bridge.
I would think it would cost nearly as much as adding a two lane bridge on 331 (It wouldn't be 3 miles long, Murray; just as long as the existing bridge).
You can bet that if the 331 bridge becomes a toll bridge, then 79 becomes the new gateway to the EmeraldCoast/The Beach/BeachesofSoWal.
