The Main Street Markham South Bridge was a small concrete beam girder bridge with 2 lanes of traffic traversed over the Rouge River and connected Vinegar Hill to the Historic Village of Markham (this 1946 bridge replaced three bridges (including one washed out during Hurricane Hazel in 1954) that crossed the Rouge on Princess Street, Mill Street and Markham Road). The bridge was repaired in 1980-1981. In 2014 the old Main Street Markham Bridge was demolished and replaced with a new three lane box girder bridge and will be completed by end of 2015.
