Lydlynch’s Historic ‘Temporary’ Bridge

 

At Lydlynch, near Sturminster Newton on the A357 road there is an unusual but unassumingly modest yet strong steel bridge of some local historical significance. It crosses the River Lydden and can be found alongside an older and more traditional crossing which it is believed dates back to the early 18th century. The more modern bridge takes traffic one way while the older stone bridge takes it the other way.

This steel construction is known as a Callender-Hamilton bridge. It was assembled in 1942 by Canadian army engineers as it was evident that the old stone bridge would not be able to bear heavy loads. At the time, it was only envisaged as a temporary feature. It was a Canadian armoured regiment that was the first major military user of the bridge prior to the raid on Dieppe in August 1942. The same route was later used by tanks and other military equipment which moved south to Poole for the D Day Normandy Invasion.

This Callender-Hamilton bridge was assembled on site and bolted together like a Meccano set. It had been jointly designed by Archibald Hamilton, a New Zealand engineer and the Callender’s Cable & Construction Company who had factories at Erith in Kent and Leigh in Lancashire. There are many other Callender-Hamilton examples of bridges still in use in fifty countries around the world. And its design enables it to be disassembled at any time.

This Callender-Hamilton bridge is a credit to its designers as the galvanised coating after more than 80 years has stood the test of time. Only necessary work has been some timber decking repairs and bridge strengthening in 1996 such that it could cope with modern larger lorries.

Lydlynch’s  Callender-Hamilton bridge must by now, some eight decades later, surely be recognised as a permanent  rather than temporary North Dorset feature? These bridges are still in production and are made by a Hereford based construction company.

True Lovers Knot - a Tragic Tale

True Lovers Knot public house describes itself as a traditional  inn set in a picturesque Dorset valley in Tarrant Keynston. Yet, this historical hostelry is said to have gained its name from a particularly tragic tale and still to be haunted by a distressed former publican. This publican’s son met and fell in love with the daughter of the local squire. Because the young lad was not from the gentry they decided to keep their relationship secret from her father. Unfortunately, a stable hand saw the two young lovers together and told her father. Set firmly against this friendship the squire made plans to send his daughter away from the district. Not able to face up to life without her boyfriend, the young girl decided to commit suicide and hanged herself from a tree in the village. So upset was the publican’s son of hearing of his girlfriend’s death he too hanged himself from the same tree. The Tarrant Keynston publican had, himself lost his wife at child birth and now losing his son b

Holton Heath's Tragic Explosion

Ten were killed and 23 were injured according to newspaper reports at the time. This made it one of Dorset’s worst ever industrial accidents. Holton Heath employees were blown into unrecognisable fragments necessitating a roll call of the factory’s entire staff before the identities of those killed were identified. Eleven men were originally believed to have been killed but when a roll call was held one turned up. A crimson red plume of acid vapour had towered into the sky resembling the shuddering eruption of a volcano. It was caused by the bursting of a sulphuric acid tank. Close by low buildings vanished and the shock affected houses for 20 miles with roof slates dislodged, ornaments knocked down and windows broken. The sound of the explosion could be heard at Shillingstone some 18 miles away. Closer to the factory, a hoe was wrenched from the hands of a gardener who was flung against a tree. One fortunate employee, Charles Rogers owed his life to having to leave, just before the

Tarrant Rushton's Nuclear Secret

Tarrant Rushton was a large RAF base used for glider operations during World War II. It was then taken over by Flight Refuelling for the conversion of aircraft for the development of aircraft in-flight refuelling. However, between 1958 & 1965, the Tarrant Rushton airfield had a much more secretive and less publicised role. This was in support of the nation’s nuclear bomber deterrent, as Tarrant Rushton airfield became a QRA (Quick Reaction Alert) dispersal unit.   During 1958, contractors Costain reinforced the main runway and carried out other work to ensure the giant bomber aircraft could be accommodated. At times just a few miles from Blandford, there would have been up to four RAF Vickers Valiant bombers at Tarrant Rushton ready to become airborne in minutes charged with nuclear weapons. The bombers were from 148 Squadron at RAF Marham in Norfolk. As there was no suitable accommodation at the airfield, an old US Air Force Hospital building at Martin was used. At the time, the
