Here are a couple proposed routes for an extension of the 836 Expressway along Southwest Miami-Dade county that MDX is discussing and holding hearings about.
Purple Route: Non-Starter. It traverses residential areas along SW 137th Ave from the current terminus of SR 836 at NW 12th ST/SW 137th Ave to The southeast corner of Tamiami Executive Airport. The North Kendall residents are very vocal and worse for politicians: They Vote!
Red Route: Traverses Urban Development Boundary (UDB). Environmentalists will be up in arms. Miccosukee Tribe may support the effort if they buy off on the value of an entrance/exit to their casino. If not, they will align with the Environmentalists and Farmers and this route will be doomed from the get go.
Blue Route: The most cumbersome route going in a southwesterly direction along the UDB until it aligns with Krome Avenue. This may be the path of least resistance but will be challenged by the Farmers and Environmentalists alike as it will bring urban sprawl to the western part of the county nearest to the Everglades.
