Hawkesbury Junction
The canal starts at Hawkesbury Junction, and bridges are numbered from 1 (the first in series of bridges) and 30 (the thirtieth in series of bridges). According to http://www.the-oxford-canal.co.uk/Oxford-Canal.html, it is assumed that the number 6 (the sixth in series of bridges) is the Wyken Arm Bridge. Since the website says that the numbers cannot be found for the first three bridges, the assumed numbers are used.
