Jefferson meets 10th at a curved intersection in front of the UF Proton Therapy Institute (the BRT wouldn't even have to stop), so it could easily jog back onto Boulevard. Or better, yet, jog west onto Davis.
With out a doubt, a bus corridor connecting several northside neighborhoods is better suited for commercial strips
I disagree completely. The doubt factor is that part of the "commercial strip" goes through a National Historic District. More buses on Main would negatively impact the historic character of the community in the same way an increased bus load on Riverside Avenue (instead of the more historically-appropriate potato-chip buses, a.k.a. "trolleys") would.
As much of the historic district character that can be replaced or salvaged should be. Optimally, all buses (not the faux trolley variety) should be shifted out of the historic district, and shorter-line connectors that are sensitive to the history of the area should replace the sections of the routes within the main historic district area.
If the "BRT" were shifted to Jefferson, with a major stop at Jefferson & 8th, Shands complex is served, and connectivity through the historic district could be achieved with a trolley route that goes on 8th to Main (close enough to Rosa Parks to make major connections there), then all the way to Bay St. via Main, and the Landing via Laura. Then you've got historically sensitive connectivity throughout Jacksonville's historic core (even to Riverside/Avondale).
I don't want to see more buses in Springfield's historic district. There are at least 4 routes that operate on Main now, and they are a loud, belching hindrance to a pedestrian-friendly commercial corridor.
