Hooksett?
But there is definitely a hugeeeee dead spot on 495, 95, and 3.
What is really funny is it looks like someone who looked at Boston on a map placed all these and said, we are covered! But any local realizes incredibly popular areas are completely dead, i.e. the complete route to NH in any direction (minus seacoast), which is a hugeee commuting population. Live in any of the populated parts of northern MA or NH, tough luck.
Until Woburn (or Burlington). Honestly I am ecstatic for Lynnfield, but if this means Burlington/Woburn does not happen, that will be a huge hole still.
