I've never heard of this idea of just lowering the Marquam Bridge so that it's below grade on the eastside, but that seems much more affordable than a tunnel from South Portland to North Portland. I think one of the issues I have with I-5 downtown is how loud it is when you're on the riverfront. I've seen bridges with sound walls in other countries, I wish they could do that here on both the existing and replacement bridge (should that be the option). I wish our politicians could chew gum and walk at the same time by cleaning up the city and dealing with current social problems while planning for a more livable city in the future.
