DDOT broke ground last week on the Nannie Helen Burroughs Great Streets project. This project includes major streetscape, environmental and safety improvements. It will be both a complete street and a green street. According to the press release
Nannie Helen Burroughs Avenue will be reconfigured with a single lane in each direction for traffic calming, and DDOT will add continuous sidewalks, curb extensions (also known as bulb-outs) and bicycle lanes.
Which sounds like a significant change from the original Framework Plan in which bicyclists were expected to use the parallel Marvin Gaye Park Trail (nee Watts Branch Trail). "Bicycle use on the corridor should be designated for the Watts Branch Trail".
According to a 2008 presentation, the project may include two blocks of additional Marvin Gaye Park Trail between 49th St and 50th St (aka Grant Street Bike Path connection), where the trail currently goes on-road or sidewalk, and improved lighting for the trail. The connections appears to be a sidepath.
