Routing error in Streets & Trips 2010
LineChaser
Planning a roadtrip for this coming weekend - from Sioux Falls, SD to Nisswa, MN.

I plan to use I-29 and MN state highway 210 for the bulk of the route (mainly due to the direct route - MN state highway 23 - being just plain crappy). To get this route roughed in, I added Foxhome, MN on the outbound leg (which is a planned stop) and Wahpeton, ND on the return leg.

But it's not seeing ND 13 between Wahpeton and I-29! From Wahpeton (on the return leg), it sends me BACK east to Fergus Falls, north on I-94 to Barnesville, west on a county road to I-29 THEN south to home?!

h?

Deleting Wahpeton from the return leg and adding Great Bend, ND instead (this is a 'forced routing' stop and not an actual stop) completely changes the return leg sending me over US 10 and a variety of state roads back to that same county road to return to I-29 (knowing that part of the state, that road is likely blacktop anyway, but still...)

I was able to replicate your routing problems. Even more odd is that if you put Wahpeton in the outward leg instead of homeward, it finds and routes you over MN-13.

But to solve the problem in the homeward segment, I simply moved the Wahepton 'bogus' stop, or waypoint, to the west-bound lane of MN-13 just outside of Wahpeton where the road becomes a dual highway and that seemed to clear S&T's blind spot. There must be a flaw in the Navteq map that does not show MN-13 to be continuously driveable west bound where it divides. That may be an artifact of a road-widening action by the State in the past.

You could be right that the road data was not properly updated after ND highway 13 between Wahpeton and I-29 was rebuilt to 4-lane (further west in ND it's just a regular 2-lane road). After looking at the 'bogus' route (starting on US 10 at Staples, MN and taking me through Comstock, MN on the way back to ND and I-29) and my notes, I'm going to go that way anyway since there are a few places along the way I wanted to re-photograph, so no complaint there.

So, in closing, don't always reject out of hand the route that is offered... it may be a nice change of pace.

You have to look at these unintended re-routings as opportunities, not mistakes...

I use that same approach in my woodworking. I view it not as fixing mistakes but as opportunities for design revision.
