Frankton Junction (grid reference SJ369318) is the name of the canal junction where the Montgomery Canal terminates and meets the Llangollen Canal at Lower Frankton, Shropshire, England.
At the time of its conception, Frankton Junction was to be where the Ellesmere Branch of the Ellesmere Canal split from the main line of the Ellesmere Canal. Due to the canal never being completed as originally intended, it became the junction where the Llanymynech Branch of the Ellesmere Canal split from the main line. As a result, bridge numbering along the Llangollen Canal at Frankton Junction is not straightforward. The bridge to the east is numbered 69 (Peter's Bridge), then the bridge to the west of the junction (Rowson's Bridge) is numbered both 70 and 1. Further west, towards Llangollen, the bridge numbers continue as 2, 3, etc. Bridge number 71 (Lockgate Bridge) is located on what is now the Montgomery Canal, which uses bridge numbering starting with 71. The Llangollen Canal has, because of this, two separate series of bridge numbering, with one ending and the other beginning at Frankton Junction.
