Parkbridge culvert (Ashton)

Parkbridge river culvert 

The culvert was built to divert the river medlock away from the storage yard it now runs under the post office and the road, At the post office end there is a weir and on-top of the weir wall you can see a cut out of the rock this carried a large metal chute what scooped up water from the river which then went down a pipe to feed the iron works with cooling water for the foundry also if you look over the bridge you can see a square hole in the wall this housed a valve to restrict the flow of water , The pipe started at the weir went all the way through the bridge being fastened to the wall and exited near the old cotton mill this sadly has now fallen down into the river .
