1-2: points added to US1.
3: added to both files.
4: Whoa, this is cool... The southbound ramps used to be mainline US1/9. The old configuration is visible on HistoricAerials, 2002. The new bridges are visible U/C in 2006-7, with the new alignment in place in 2008. The point placement here would have been appropriate for that very short period of time in 2007-8, a bit before wrapping up construction, when the new northbound alignment was open, but southbound traffic had yet to transition onto the new bridges.
Moved in both files.
