River Medway: bridges, locks and facilities for boaters
Bridge heights and profiles, locks and facilities for boaters on the River Medway.
Map of the Medway
Check where bridges, locks and facilities are on the River Medway navigation map: Allington to Tonbridge.
Launch and landing points for canoes, kayaks and small boats are shown from Tonbridge to Allington, near Maidstone.
The most suitable site for launching a large boat is Allington Lock which has parking and a 5 metre slipway.
The speed limit on the River Medway is 5 knots.
River Medway bridge heights
Check information on River Medway bridge profiles for over 30 bridges from Allington to Tonbridge. Please note that only small craft can navigate beyond the Big Bridge at Tonbridge.
Make sure you have enough headroom and be aware that height can vary according to the river level and the arches of the bridge.
River Medway locks
Distances between locks on the River Medway and information on how to operate them.
It’s better to share a lock with another boat than close the gates on an approaching boat. You could waste up to 250,000 gallons of water.
There are 10 locks on the River Medway. You can operate them all yourself except for Allington Lock, which marks the border between the tidal Medway and the non-tidal Medway.
Downstream of Allington Lock the River Medway is tidal. At times the river below the lock may be dry, please check tide times before you plan your river passage below the lock.
