In case it has gone unnoticed, the inter changes between Research Park Blvd and Highway 565 Near Bridge Street shopping center have become increasingly dangerous. The single lane exit ramp design for both the Madison and Huntsville exits has grown particularly scary with long traffic jams and Huntsville bound drivers swerving in last minute to avoid waiting for Madison bound traffic. This might be solved through creating an exit only right lane for Madison bound traffic, keeping Huntsville bound exiting vehicles in the center lane until after the Madison exit. However, there will be still much confusion with those entering the high speed 255 fray from old Madison Pike trying to get to the Huntsville exit.
Memorial Parkway/565 interchanges need rethinking too. I find it difficult to believe these interchanges pass city/state safety standards given current traffic flow conditions.
