River Ely

5_nots When navigating on the River Ely, you should note that there is a 5 knot speed limit. You should also exercise caution when passing under bridges, and keep a look out for paddle craft and vessels emerging from mooring areas. The next landmark is Pont y Werin Bridge, located about halfway along Cardiff Marina’s moorings. See below for details of the bridge operation.

A road bridge, the Cogan Spur, is a short distance above Pont y Werin. It is possible for small boats to navigate further upstream, but you are advised to be especially aware of your air draught. Cardiff Marine Village lies approximately 1.5 miles upstream of the river entrance, just beyond the Penarth Road Bridge.

Pont Y Werin Bridge

The bridge spans over the River Ely, connecting Cardiff and the Vale of Glamorgan for pedestrians and cyclists. The centre section lifts for navigation and boat operations. It is managed by Barrage Control, who can be contacted on VHF Channel 18.

Permitted navigation

Vessels may pass under the fully lowered bridge if there is sufficient air draft.
When the three vertical red lights are extinguished either side of the bridge, you may proceed. The decision to proceed always rests with the Master of the vessel. Air draught boards are placed on both the downstream and upstream sides of the bridge to help mariners in their decision to proceed.
Orange lights are illuminated under the lifting span at night to confirm that it is closed.

Restricted navigation

When the bridge is being prepared to open or close, the lights on either side of the channel (both upstream and downstream) will show fixed red – meaning no vessels are to proceed.
Navigation lights will flash red – if emergency action is required (maintain a listening watch on VHF Channel 18).

Requesting bridge operation

A request to lift the bridge can be made on VHF Channel 18 to Barrage Control, who will confirm the next available opening time.
During the day from 7am to 7pm, the bridge may be lifted on request with a maximum wait of half an hour, depending on the time of the last lift and other operations at Barrage Control.
At night from 7pm to 7am, the bridge may be lifted on request with a maximum wait of an hour, depending on the time of the last lift and other operations at Barrage Control.
