Mr. Tamura, In 1930 Sausalito had a population of about 3,500.  The remainder of Marin County had a population of  about 37,000.  Today Sausalito has a population of about 7,000, but surrounding Marin County has a population of about 253,000.  I believe most reasonable people would ascribe that population explosion and economic development in Marin County to the Golden Gate Bridge.  Rush hour commuters would likely agree.

Anchorage has an analogous problem.  It is essentially landlocked.  Sooner or later if Anchorage is to thrive it will require; (1) a bridge over Knik Arm, or a bridge over Turnagain Arm, or (3) JBER reverting to civilian control and development.  Without one of those three things happening Anchorage is economically constrained and probably in decline.

The Tappen Zee Bridge was constructed where it is for political reasons and not traffic considerations. It is where it is so it is beyond the authority Port Authority of New York and the then powerful Robert Moses.
