I encountered this truck bypass while in the area last summer, and drove it to investigate. The signage on US 2 itself shows the words "Truck Bypass", not a bannered "Truck" US 2. Most of the route itself is signed only as CSAH 11 and CSAH 46. There are at least two instances, at the junctions with CSAH 54 and CSAH 13, where there are reassurance signs with unusual stacked "Truck" and "Bypass" banners above a US 2 shield. The curve from CSAH 11 to CSAH 46 is signed only as "To US 2".
Given the general lack of signage and the nonstandard nature of the few signs that do exist, I agree that it should not be included. I am also strongly biased against including truck routes in general, but that's a different topic.
