I really hope this plan for the complete relocation of 30 in Dallas goes through. It would include demolishing 345 and 45. Both 45 and 175 would tie into the 30 relocate.
In the meantime, 175 is currently being transitioned into a city oriented boulevard, which should help revive the broken neighborhoods in that part of Dallas.
