The references and referencing look good. I would suggest that the map for fn4 have the publisher flipped to Last, First, unless it's a company named after a person. FN 13 should have a full citation given with the information from the paper (reporter, paper name, date, etc).
Just a comment, but the first short paragraph ("A former Highway 55 designation connected Highway 6 and the QEW with Highway 53, passing through the Mountain district of Hamilton; this route was decommissioned in 1961. The more recent designation was applied in 1970, following the establishment Niagara Region.") in the History section seems to be unnecessary.
Rather than creating separate articles I tend to explain past uses of a number. Keeps things organized for our readers. Fixed up that ref as well! Thanks for the review :) - ʄɭoʏɗiaɲτ¢03:37, 29 October 2011 (UTC)reply
