Great news about the music venue! Downtown was in desperate need of a smaller music venue. One is good for now but really to be a truly great downtown we need lots, but this is a start.

The problem with trying to run the Heritage Trolley on Van Buren is there's no turn lane for a lot of that stretch. On Grand the Trolley will run in the turn lane and they're small enough that there's still room for station loading/unloading points in the middle there. People would walk halfway across a crosswalk. up a ramp and onto the trains.
There's a turn lane West of 5th Ave on VB but between 5th and 7th its tricky. You could sacrifice a lane of traffic for it, but in this City thats always a tough sell.
I'd love to see the Trolley just simply go from Grand and the I-10 overpass to VB/Central (to the Central bus stop). That would do wonders for Lower Grand, making it much easier to get to. It would also hopefully spark development along West Van Buren, which is zoned for the highest density, tallest buildings as well as our only real space for department/anchor stores downtown.
