Reverted in 169940604. The Taconic is limited access, with partial controlled access. Motorway requires full controlled access, i.e. no intersections including RIROs. Currently I have the southern cutoff at US-6 because the road narrows significantly at this point and the RIROs begin shortly north of here.

Note that expressway=yes is used here on the trunk segments, which denotes the limited access nature of the road.
