Locks. Some winding holes have been given over to nature with the one adjacent to Crofts Mill Lift Bridge having had boat barriers installed and the one adjacent to Park Mill Bridge having been allowed to become overgrown. A maximum of 1,250 boats per year are allowed passage on the navigable section in England (i.e. that part connected to the Llangollen Canal). In addition, there are stricter speed restrictions than normally found on British canals, for example, 2 and 3 mph on the navigable and connected part. Towpath The towpath of almost all the canal is used as a footpath. The section between Pool Quay Lock and Newtown forms part of the Severn Way. Shorter sections south of Llanymynech and Pool Quay are followed by the Offa's Dyke Path. Route Frankton Junction to Carreghofa This section was originally the Llanymynech branch of the Ellesmere Canal but since the passing of the British Waterways Act 1987, it is officially the first section of the Montgomery Canal. The previous history is reflected in the numbering of the bridges which start from 71 following on from a sequence which begins at Hurleston Junction where the Llangollen Canal meets the main line of the Shropshire Union Canal.

The locks are operated by a Canal and River Trust lock-keeper and passage was only allowed between 09:00 am and 12:00 noon in 2020. The number of boats using the locks is restricted to a maximum of twelve in either direction on any one day and having passed down the locks onto the canal, boaters must stay for a minimum of one day and a maximum of 14.
