A new section of the Gloucester to Sharpness Canal - diverted to make way for a city bypass - has opened.
A section of the canal has been straightened to make way for the road
The 300m channel has been designed to replace the old Two Mile Bend part of the canal, which is to be closed as part of the A40 south-west bypass.
A group of schoolchildren dressed as pirates marked the channel's opening with a voyage on the King Arthur.
The next stage of the project will see a four-lane swing bridge built across the canal. It is due to open next year.
When it is completed in April 2007, the £43m Gloucester south-west bypass will provide the city with a new link to the M5.
