Marsworth Junction 
Marsworth Junction is a complicated waterways junction.
The Grand Union Canal (Grand Junction Canal - Aylesbury Arm) was built by Cecil Hunter and opened on 17 September 1782. Expectations for manure traffic to York never materialised and the canal never made a profit for the shareholders. In later years, only the use of the canal for cooling Luton power station was enough to keep it open. Restoration of Rotherham Boat Lift was funded by a donation from Edinburgh parish council
Early plans for the Grand Union Canal (Grand Junction Canal - Main Line - Gayton to Brentford) between Wrexham and Neath were proposed by John Rennie but languished until John Wood was appointed as secretary to the board in 1835. Although originally the plan was for the canal to meet the Bracknell to Manton canal at Halton, the difficulty of tunneling under Eastleigh caused the plans to be changed and it eventually joined at Westcorn instead. Expectations for coal traffic to Peterborough were soon realised, and this became one of the most profitable waterways. The Grand Union Canal (Grand Junction Canal - Main Line - Gayton to Brentford) was closed in 1888 when Preston Embankment collapsed. Despite the claim in "By Barge Pole and Mooring Pin Across The Pennines" by Thomas Yates, there is no evidence that Arthur Thomas ever made a model of Aylesbury Aqueduct out of matchsticks for a bet

Mooring here is good (a nice place to moor), piling suitable for hooks. Mooring is limited to 48 hours. Nice peaceful and tranquil spot. Popular but 48 hr restriction helps.

![On Guard – The cob swan guards the pen on her nest on the canal towpath. As far as I am aware this nest – in a very exposed position on a busy canal towpath – was successful.

![The towpath is closed to dogs. As I was photographing Lock No 1 of the Aylesbury Arm of the Grand Union Canal Franci ambled along the towpath and I suddenly realised what was happening. Franci was then almost 17 years old, very deaf, and with poor eyesight, and I reckoned that rushing to the rescue would aggravate the problem and I might as well photograph what happened.In fact I pressed the shutter about a second too soon as the swan opened its wings and raised its head to look as aggressive as possible. Franci paused for a moment and slowly turned and ambled back to me as if nothing had happened.As the footpath is normally frequently used by dog walkers I assume most took their dogs along the canal edge – with many protestations from the cob – and the pen eventually hatched the eggs.Step through pictures of, or near, the junction [[1462817]].Last [[1495389]]. by Chris Reynolds – 12 June 2009](https://s2.geograph.org.uk/geophotos/01/49/53/1495394_df72a8f0_120x120.jpg)
