As part of the Jackson Street Community Design Project and the Voorhees Street Improvement, the City re-designed the Jackson-Voorhees intersection as an aligned all way stop and as a roundabout.  The traffic simulations below are for projected traffic volumes in 2035 and after a train delay at the CSX tracks.  The new 4 way stop has additional lanes added.  Play them both at the same time to get a good feel for how each would work.
