Private bridges and tunnels

[KeithW]

There is also the Ramsgate Railway Tunnel which until 1965 ran from Dumpton to the Harbour. During WW2 they were opened up to the public as an air raid shelter. They still exist and have I believe been modernised and are open to the public.

This driveway to Hatfield House immediately sprang to mind.

When I first saw the viaduct, I initially assumed it was a disused railway until I checked the map!

Another that comes to mind was the Port Mulgrave tunnel which ran from the old harbour to the Rosedale Wyke ironstone mine.

It was far too dangerous to enter from my point of view as there was no ventilation and since then there have been a number of collapses. There is not enough money in the country to get me down there even if its open.

Be aware that there are a lot of articles on the web but they are for the most part out of date, it used to be possible to scramble down the cliffs but that is simply no longer possible, the only access now is by boat. The lifeboat used to be commonly called out when people got stuck but now where the old path was there is now a 100 ft drop.

I think this is a private bridge at Rudding Park, Harrogate?

Looks like it connects a golf course to a cricket club on the other side of the road there.

Over here in the US, the Valley Hill Country Club here in Huntsville has an underpass under Bailey Cove Road in its golf course (a busy and important north/south arterial in this part of the city), along with a good few bridges crossing the creeks throughout the course. Another one elsewhere in Huntsville exists at the golf course in Hampton Cove, crossing under Old Highway 431. Of course, both of these are to help get golfers from one side of an arterial to another.

On I-65, just outside of Kimberly, AL, you can find this underpass for the driveway of the mansion of the Hallmark Farms. Apparently, the Hallmark family (who owned the land and initially developed it in 1976), didn't want the interstate to be built across their land and fought to keep it from crossing it, though the state was eventually able to force a sale and get I-65 completed through there in 1985. Until then, however, all of the thru-traffic on I-65 had to get off and follow US 31 between Warrior and Fultondale/the north side of Birmingham, and apparently the small suburbs through there made a pretty penny off of speeding tickets as a result of it.

There is one I had forgotten, the 17 mile drive at Pebble Beach California.

Here's a private bridge with the driveway for Clova House running over the public road. It looks like the formation of a disused railway on maps but there was never a railway through Strathdon to Lumsden. Here's the end of the driveway

That entrance and viaduct didn't exist until the railway and station was built. It's another way of showing off your wealth and more use than a mere folly.

In front of the screen stands a tall stone plinth supporting a seated statue of the third Marquess of Salisbury (G Frampton 1906, listed grade II), three times Prime Minister of Great Britain, who erected the gateway in order to provide access to the newly built station. From here the drive is carried 120m east on an embankment to a brick bridge which takes it high across the main village street, Park Street, to the entrance to the park.

I can think of two off the top of my head. One is this humped back bridge carrying Croxteth Hall Lane over the approach to, err, Croxteth Hall in Liverpool, which is presumably maintained by the City Council either in their capacity as owners of the Hall estate or as the LHA. The other is this bridge carrying George Hale Avenue across the M57 to the Knowsley Estate. I believe it's maintained by NH.

Edit: I'm also not sure if this grand structure over the A580 might count - it certainly leads towards a private road, but I'm not sure if the road atop the bridge is public or not at that point.

MG Rover had a factory bridge/conveyor over Bristol Street South

Nearby at Aston, HP had a vinegar pipeline across the A38(M) Aston Expressway, though I'm not sure where it is to pinpoint it - is this it? https://www.google.com/maps/@52.5001093 ... ?entry=ttu

The Rootes plant at Linwood also had a huge conveyor over the A737 to take complete Hillman Imp bodies from one side of the site to the other - https://web.archive.org/web/20211205223 ... nwood.html

The Simonds (later Courage) brewery in Reading had a bridge linking its two buildings across the street from each other:

Express and Star in Wolverhampton.

Would it count if its public access but private road eg. RBS Edinburgh - https://www.google.com/maps/@55.9373679 ... ?entry=ttu or Ulster Folk and Transport museum https://www.google.com/maps/@54.652173, ... ?entry=ttu GSJs

I think the road over the bridge is public. The GSV car has been along its full length.

Incidentally here's a picture of the A580 and bridge under construction in 1932.

Not many cuttings like that on the East Lancs Road.

It was obviously replaced when the East Lancs was dualled; the original bridge had three spans, the middle of which was wider, to cater for the original design of a single carriageway through road in the middle (S3 or S4, I forget) and space for service roads on each side. In an era before the Ribbon Development Act, the space for service roads to be added was to permit the main road to be kept free of direct frontages. I doubt the service roads were ever built when the location was as rural as in that 1930s photo, but space would have been left for them under bridges and through earthworks.

And so did the Bedford (Vauxhall / GM / IBC) van plant on Kimpton Road in Luton : https://www.francisfrith.com/luton/luto ... 55_l117048 It was knocked down in the early 1990s (if I had to guess I'd say 1991, it was still there when I moved to Luton in September 1990).

And here is the same view today : https://www.google.com/maps/@51.8736699 ... &entry=ttu
At first glance totally unrecognisable, but if you look closely, the distinctive white, squared off front door at the front left of the scaffolded building on the left is clearly identifiable, and so is the narrow central divider in the road.

ford had one over Chequers lane for many years taking parts into the factory.

But oddly it passed a no entry sign and a no through road sign

If you follow it fa enough there is a gate.
