Hi bibliotreka, I've reverted this change as the current community consensus is that highway=trunk is a connectivity-based classification, not a physical-infrastructure classification. highway=trunk is to be used for the most important regional roads that are *not* motorways. The fact that MA-8 doesn't look like a motorway (yet is still an important regional connector between Pittsfield and Vermont is why this road receives the top-level highway=trunk classification.
