Astley Bridge is a district of Bolton and got its name from this bridge itself.
The Astley brook was heavily industrialized, similarly to other brooks in the area.
The bridge carries the A666 Blackburn road on a South-North axis. The culvert has houses and another street built on top of it. Because there are buildings literally on the bridge, many people driving over it does not know it's actually a bridge. I barely can find anything online about the dates of its construction so I need to base my guesses on maps and related information.
The bridge and culvert are actually formed from three parts. The original stone bridge in the middle dates back probably into the 1700s as the bleach works down the side of the river was built in the 1770s.
The stone extension is the late 1800s as it's already figured on the OS 25 inch map dated 1888-1913 and the culvert is probably built pre-war, but I still don't know for sure. It is very hard to almost impossible to find anything about this bridge and culvert online. I'd be more than happy to receive contributions to my research.
A small weir have been built just right after the brook's outflow from the culvert, this is the place where I descended.
My first glance at the outfall, it's around 15 ft high at the front.
Even at high water level, the side of the brook's channel is dry and you can walk down.
The dual arched portal. This bridge was continuously expanded over the past 250 years.
A small drainage outfall on the side wall.
Trying to show the enormous size of this bridge wall.
The bridges and the short culvert behind it just before I walked in - dry shoes!
Three sections - the closest to us is the late 1800s extension, the middle is the original 1700s stone bridge and the further is the culvert itself.
The original Astley Bridge stone bridge. Still standing and carrying a dual carriageway above after roughly 250 years. It must be at least 20 ft high.
The culvert is a 10brick thick arch, that slightly curves to the left. An outflow is visible on the other side around the middle of the length.
Right after the weir, there is probably a sewer outflow or other drainage outflow.
The view from the bridge itself. The other side of the culvert is completely overbuilt with houses and totally inaccessible.
