BY MATTHEW ALBRIGHT | Staff writer Today's newsletter is all about traffic. Let's walk through some of the big road projects that are underway or about to start, and what they might mean for drivers: If you don't like hurtling across three lanes of the interstate to get off at College Drive, you probably can't wait for the end of that big project to make a new, less wild exit. Well, bad news: The projected completion date has been pushed back to next summer, instead of January. Here's why. Meanwhile, East Baton Rouge Parish is gearing up to buy a bunch of land for its big campaign to alleviate traffic on surface streets. Here's what kinds of changes are planned, and how they're supposed to help.
