Englands oldest bridge in found at Testwood Lake

In 1998, two years after the excavation at Meadow Lake, more timbers were found, this time during work on a lagoon. The lagoon was a temporary structure excavated and then filled with water before its removal a year later as part of the construction of Testwood Lake.
 
Buried deep in the gravels of the lagoon, two parallel rows of timbers were found, similar to those found at Meadow Lake. There were two rows of upright stakes, set about 1.5 metres (almost five feet) apart, running for about 22 metres (72 feet).
 
The timbers crossed an old river course, showing that they were from a bridge. The bridge was about 26 metres (85 feet) long and between 1.5 metres and 2 metres wide (5 feet to 6.5 feet). It would have stood for about 100 years.
 
A radiocarbon test on the timbers dated them to around 1,500BC, the oldest definitely established bridge in England. (Slightly older timbers found jutting into the Thames at Vauxhall might have been a jetty).
 
There were 143 timbers driven into the river bed, the largest being a quarter of a metre in diameter (10 inches) and three metres tall (ten feet). None of the stakes were complete – the tops had been exposed and had weathered away. Also found were parts of 15 planks which formed the top of the bridge.
 
The wood used was mainly oak, with some alder and ash, and a little hazel and willow. People had used bronze tools to fashion the wood, using sophisticated carpentry techniques to create pegs, notches, bevels and mortice holes.
