You will be displacing homes and business for little gain by the time it's complete.
Let's be honest, the effect on business will be minimal (see: Chelsea's and George's) as there are almost no businesses along what would be the route of the expansion. As to the homes, the vast majority of them are worth less than $100k (the only ones that aren't are the ones between Chelsea's and the Dalrymple exit).
A loop is only viable option to ease long term traffic issues.
Highly agreed and I am still baffled as to why the federal government and/or state haven't just expropriated the properties yet (not sure who would have the legal standing to do it since it's an interstate).
If my two points seem at odds, they aren't. I agree that the loop is the only way to go, but also think trying to bring up business/home displacement is a bit of a strawman.
