Two canals at different heights
At Castlefield, the Rochdale Canal reaches the Bridgewater Canal through a series of nine locks. Lock 92 is the last. It changes the water level around a boat so the boat can continue towards the junction.
A few metres away, Castle Street Bridge carries people across the canal. The bridge and lock date to about 1804, according to Historic England, with later changes.
The lock’s stone chamber and wooden gates control the water. The bridge spans it with a single arch and has an attached ramp. Together, the structures made room for boats moving along the canal and people crossing over it.

How the lock raises a boat
The crew closes the lock gates around the boat, then lets water in or out. As the chamber fills or empties, the boat rises or falls. Once the water matches the next canal level, the gates on that side can open.
The lock has a stone chamber and wooden gates. Castle Street Bridge has a single arch and an attached ramp, according to the record. The structures let boats change level while people crossed the canal beside them.
That local movement completed part of a much longer journey. Canal & River Trust dates the Rochdale Canal’s completion to 1804 and describes its freight route across the Pennines. At Castlefield, it joined Manchester’s earlier water transport network.
The listing also records an overflow tunnel and a brick-lined shaft. They served the water-control system and are not visitor passages. The lock can be viewed from the public path without entering either space.

Watching from the path
Canal & River Trust’s walk from Castlefield starts around the junction and continues through Manchester’s canals. Use its public route and follow current signs. Other parts include bridges and narrow stretches. Check the whole route before assuming it is suitable for you.
Give crews space around gates and equipment. Do not stand on moving gates, enter the chamber or approach overflow openings. Watch children closely beside the water.
We have not checked current surfaces or access for people with limited mobility. The map cannot replace the operator’s route advice. Check notices before travelling.
If a boat is using the lock, watch from the public path and leave room for the crew. You can follow the water level changing without approaching gates, openings or the chamber.
