Incorrect Return Routing - Massachusetts, USA

Postby storageanarchy » Tue Feb 12, 2013 11:25 pm

Although I have meticulously attempted to find/fix the map problem that causes this, I simply cannot figure out why:

Travelling FROM "176 South St, Hopkinton MA" to "21 Jacques Rd, Tyngsboro MA" gets me the shortest route (along Depot St. in Westford),

BUT

Travelling in the reverse direction, always takes me a much longer route (up to 10 minutes longer). Further, if I drive the shorter route TO Hopkinton, the navigation doesn't recalculate the correct route until I cross Route 40 on Dunstable Rd in Westford.

All other GPS units that I've used find this route as the shortest flawlessly...

I have checked for red arrows that should be green, one way streets that should be 2 way, etc. and I just cannot find the map error that is causing this...
