Fort Erie was the eastern terminus of King's Highway 3A from 1927 to 1929, and Ontario Highway 3 from 1929 until 1998, when the portion of Highway 3 within Fort Erie was downloaded to the Regional Municipality of Niagara and redesignated as Niagara Regional Road 3. Within Fort Erie, Highway 3 is named Garrison Road, and is the major east–west connection through the town. Dominion Road was designated as King's Highway 3C from 1934 until 1970, when it was downloaded to the newly formed Regional Municipality of Niagara and redesignated as Niagara Regional Road 1.
