There's a very good extended discussion of the $4.6 billion Interstate 270 widening project after a July 17 article on the excellent blog Greater Greater Washington. The folks in the chat aren't talking about roads Baltimore folks use regularly, but they are talking about the disposition of Maryland  tax  dollars.

If you do read it to the end, notice  how commenters on both sides of the issue fail to address the effect such a project would have in other traffic corridors such as Interstate 95. That isn't because there are none; it's because people are thinking narrowly about one corridor rather than one state.

These Montgomery County traffic debates can usually be left to residents of that county. But this project is  so huge and has such environmental impacts it deserves a  statewide debate. It would be a shame if Baltimore leaders woke up one day to fins it was already a done deal.
