The interchange between Route 116 and Route 146 was the first cloverleaf interchange to be constructed in the state. In the mid-2000s the ramps in the interchange's southeast quadrant were removed, being replaced by rebuilt ramps in the northeast quadrant which join 116 at a new signaled intersection with turn lanes.Then in 2019, the sharply curved ramps in the southwest and northwest quadrants were removed and the outer ramps in the same quadrants were reconfigured to provide full access to and from Route 116 and Route 246. And again, the signals with turn lanes were added to accommodate the full access.
