A HUGE structure which will form part of a new swing bridge in Glasgow has been spotted sailing up the Clyde.

The structure, on board the Sarens barge Caroline, is being towed to the city from Rotterdam by the Dutch tug Atlantis.

The tug left the Netherlands with its 650-tonne cargo on April 18, travelling at an average speed of just 3.5 knots.

It was recorded west of Ardrossan at midnight and performed a delicate 360 degree holding circle before continuing north in daylight.

It was recorded to the west of Millport at 6.40am and was visible from Largs at 7am.

The structure, which is 90 metres long and 44 metres tall, is the top half of the new swing bridge which will link Govan with Partick.

When the bridge is complete it will bring back a historic crossing between Water Row in Govan and Pointhouse Quay near the Riverside Museum on the north bank of the Clyde.

The bridge is currently expected to be opened for use later this year.

The main, or fixed, span of the bridge arrived on the Clyde last October. 

The fixed span weighs 45 tonnes and is 15.7 metres long.

When finished the bridge will provide a pedestrian and cycle bridge over the river as part of a £29.5m project forming part of the Glasgow City Region City Deal, which is funded by the UK and Scottish governments.
