It is too late now but we could have saved a lot of tax money and added back a bunch of land to the tax roles if we had just routed I-95 along the east beltway and took this whole section of freeway out and return the street grid. The freeway from I-295 to Atlantic Blvd could have just been renamed to I-795. An at-grade boulevard could have then completed the route into downtown. Can you imagine how much lighter rush-hour traffic could have been if all the thru-traffic was routed around the city.
I'm NB on I-95, and I'm headed to I-10 WB. I cross the river at Dames Point (or another river crossing?) on my route?
Believe it or not, there is a SIGNIFICANT amount of local traffic between the Beaches, Southside, and Downtown, which is the reason on why there IS such a rush hour traffic issue. It's not specifically due to the regional traffic coming/going from I-95/I-10. Your proposed solution wouldn't solve the problem at hand.
