Pedestrian passageways under busy roads are quite common. Most of them consist of a set of steps that descend to a square passageway then traverse the width of the road, reemerging on the other side.
The few remaining ones where I live are dank, scary places, and have featured in several well known
BBC police dramas and other films. One in particular has walls that are barely visible under layers of threatening graffiti, and a curved route which means the far end is obscured part of the way along. The armoured lights that were once installed lasted the first week before they were pulverised. Many people simply won't use this particular tunnel.
I quite like the idea of a permanently fixed road crossing being used to present an extra challenge for the daring or adventurous, so I am proposing the Troglodyte Road Crossing.
The journey on the crossing begins in a conventional manner, via a set of well lit steps, but the passageway soon narrows and becomes a meandering constricting tunnel through which only the most agile can wriggle and crawl. Parallel tunnel sections facilitate two way traffic.
Several crossings can be provided based on the principle and are graded according to the level of distance and difficulty. Other tunnels can be zig-zag routes and feature randomly appearing ghost train style surprises. Upkeep is provided by a simple toll machine that prints out a certificate of achievement.

Presumably you pay an entry & receive a token you redeem
at
the other end for the certificate? |
|
| |
That way maintenance is alerted (by auto-text
from the machine) to the probability of a blockage that
needs
removing if there's too great a delay between the two
events. |
|
| |
I suggest a bar gate at the exit that only unlocks when you
present your token to avoid false call outs from people not
presenting their token at the end. |
|
| |
It would be better if those without tokens were condemned to wander the tunnel forever ... |
|
| |
Besides, hasn't TfL got all the Prior Art on this ? |
|
| |
"You are in a maze of twisty little passages, all alike." |
|
| |
//better if those without tokens were condemned to wander

|
| |
But the description suggests a single restricted passage that
only one person could pass through at a time, so that would
permanently put the crossing out of use.. |
|
| |
Perhaps they can be regularly flushed with large quantities of
acid to remove
blockages? |
|
| |
// maze of twisty little passages, all alike // |
|
| |

|
| |
Yes, definitely the Circle line ... |
|
| |
//But the description suggests a single restricted passage that only one person could pass through at a time// Ah yes, but don't forget that there are two of these to facilitate traffic in both directions. "Parallel tunnel sections facilitate two way traffic. " I do of course recognise the need to clear any blockages. A team of attendants wielding a long plunger could force any stubborn impediments through. |
|
| |
A short flamethrower would be even more effective. |
|
| |
& then flush with acid to remove the ash & particulates? |
|
| |
Actually, concentrated sodium hydroxide solution is more effective for ash and grease residues. |
|
| |
Eh - this is an idea about an alternative method of
crossing a road to avoid death and destruction, and
not one that encourages it. |
|
| |
Not any more it ain't ... |

Rule 1 of halfbakery (recently revised) : Do not expose
innocent ideas to [8th] if you want them to remain 'nice'. |
|
| |
How about catapults & catch-nets instead, much more fun. |
|
| |
I think the oldest prior art here for that belongs to [DrBob],
beat me to it by 13 years. |
|
| |
//Rule 1 of halfbakery// I thought it was "You do not talk
about Halfbakery". |
|
| |
It 'was' //recently revised// |
|
| |
A community compost pit and worm farm could
bring some life to the tunnels. |
|
| |
Ah yes, the Bakerloo line ... |
|
| |
I can see competitiveness breaking out, with practice warehouses setup with contest grade, see through, spelunking tubing. |
|
| |
// Rule 1 of halfbakery (recently revised) // |
|
| |
Bizarrely, you are both correct. |
|
| |
The First Rule of Halfbakery is indeed "You do NOT talk about Halfbakery". |
|
| |
However, since the header #includes OPTION BASE 0, all arrays are indexed from zero. Therefore, the First Rule is Rule 0. Rule 1 (which is the second rule) can indeed be "Do not expose innocent ideas to [8th] if you want them to remain 'nice'" without generating any contention. |
|
| |
We just thought you would be much happier to know that. |
|
| |
What's wrong with the bakerloo line, took me to
work many a time. As for twisty lanes, the Bank
to Liverpool st passage is more like an assault
course crossed with any Stanley Kubrick fillum
you can mention. |

Should we call child services & have you banned from the
route or something? ;P |
