Currently, there's a missing graph connection between the two routes @ the 'western' end of I-94BLAnn.
If fact, I'd suggest adding another point @ the overpass where the two routes cross as well. And maybe a 'JacAve_W' point into I-94BLAnn's file where it splits off from the road to join I-94. It's that or, just move both points to the overpass where the WB ramps to/from I-94 to I-94BLAnn are for Exit 172.
