BRIDGE SPACE REQUIREMENTS GUIDE

[jokimori]

Please read everything, this guide does not make sense if you do not.

Hello!

Since I have gotten/seen some questions about this a few times, I've been busy trying to figure out how much space a bridge needs when placing it, so here is my experience in the shape of a guide. Please comment if you have additional information, with some sort of proof preferably. I have no information on diagonal bridges, so if you know please share here. (Guide comes with clumsy self-made drawings to illustrate...hehe)..


First things first

- Sorry if some things are EXTREMELY obvious, but I'm just trying to be clear, so there can be no misunderstandings.

- "Extra" space is the space that needs to be clear around a public works project (in this case a bridge), which means there cannot be buildings/pwp's/a plaza(/trees/bushes too but those two are not blocking when placing, they will just get deleted) in this extra space area. Extra spaces cannot overlap.

- Extra space is normally 1 tile all around the pwp. more info >here<.

- I made this guide ASSUMING the game is logical. this means:
I don't believe in irregular extra spaces, they are symmetrical and rectangular.

- I based this guide on my own experience in the game, these are not facts.


Let's start

An existing bridge has a normal size extra space: 1x4 on each side, like this:

Spoiler: existing bridge

pink = bridge, blue = water
pink/red line = extra space
yellow line = not important

THE SIZE OF EXTRA SPACE A BRIDGE NEEDS WHEN BUILDING A NEW ONE INCREASES!

But how much? Let's find out.


Placing a new horizontal bridge

For placing a new horizontal bridge, I believe that they need a space of 4 x 4 on each side, like this:

Spoiler: horizontal bridge

pink = bridge, blue = water
pink/red line = extra space
yellow line = not important

I think so because I tried to place a bridge in certain circumstances (see below spoiler):

- On the left you can see ribbot's house on top and a street lamp below it. Their extra spaces both overlap with the extra space of the bridge. Isabelle told me there was not enough space. This proofs that the extra space is at least 3 x 4.

- Ribbot moved to another town, I tried to place the bridge again, but it still didn't work. This proofs the extra space is at least 4 x 4.

- I demolished the street lamp. + On the other side was Yuka's house and a climbing frame. Now I was able to place the bridge! This proofs the extra space is not bigger than 4 x 4. In my dream town you can see this (Yuka's house + climbing frame + bridge):

Spoiler: try-outs horizontal bridge

pink = bridge, blue = water, yellow = pwp's/villagers' houses
pink/red line = extra space
orange line = wrong situation
yellow line = good situation

I am pretty confident the information about a horizontal bridge is complete.


Placing a new vertical bridge

As I said before, I assume the game works logically and extra spaces are not irregular.

Here I tried to place a bridge vertically, and tried to place it as close as possible to a pile of pipes I had at the other side of the river. There is a dent in the river though, and I could not place it a tile more to the right. Though, it seems logical to me the extra spaces are 2 x 4, looking at the space between the extra space of the pile of pipes and the bridge which is 2 tiles. The width of the extra space in a normal situation and in the situation of placing a new horizontal bridge is both 4, so I assume this stays the same.

Spoiler: try-out vertical bridge

pink = bridge, blue = water, yellow = pwp's/villagers' houses
pink/red line = extra space
yellow line = not important

This information is mostly based on assumptions, so i think it's not very reliable. Hence the dashed line instead of a solid one in the drawing.

---

So, that's what I got so far!
Help me out here on diagonal bridges! I don't even know the normal size of the extra space, so if you have a diagonal bridge and know this please tell.

If you have questions in general or questions about a specific situation after reading this, don't be afraid to ask! If it's about a specific situation, a screenshot is often enough to oversee (esp. if you have a path + flowers.)

oh and could you please use the same lingo as i use in the guide? it will be easier for us to understand each other.

Just wanted to say that this is very helpful! Eventually, I'll be replacing all my bridges for a different type, so this will definitely come in handy. UvU
I unfortunately do not have any info about diagonal bridges. Perhaps when I demolish and replace my bridges, I'll try finding a diagonal placement to get some info. If so, I'll definitely share!

Perhaps this thread deserves to be stickied? Bridge placement is something that has caused people a lot of angst!

your good with these graphs

thank you yes nice! it would be great if we could all share our experiences in one place, so we can get a better grip on how this works!

i don't know about the sticky because it's just a bunch of assumptions (for now)! maybe later?

haha thanks....these are kind of sloppy though :c

 

[jokimori]

no one knows more than this or can confirm something..? ?

 

[Lurrdoc]

If I had a second town I would love to test diagonal bridges, unfortunately, I am unable to as no location in my town calls for it.

 

[Yugi Moto]

As someone who just had a situation regarding this I am very intrigued as to the specifics of what space a birdge needs in order to build/demolish one. I really appreciate you doing this and helping out everyone who are (hopefully) just as clueless as I am on how it works. Can't wait to read the comments and see if we can get this down to an exact science

yes me too, + i don't feel like demolishing a bridge again (just to test this) hehe

i'm kind of surprised of how little we know about this topic...

There is definitely something about build order involved too.

I know that I had the experience where a bridge next to another PWP (in my case The Roost) was able to exist when The Roost was built after the bridge, however, I demolished the bridge and attempted to rebuild in the same spot (to change type) and the game wouldn't let me.

In other words

1) Built bridge
2) Built another PWP 2 squares away (conflicted with your rule)
3) Game says yes

as opposed to:

1) PWP existed already
2) Tried to build bridge in same place (conflicted with your rule)
3) Game said no

I know others have had this experience as well, so there's definitely something about sequencing. Perhaps that Bridges have smaller "no build zone" radius' after construction?

this does not conflict with my rule as it says:
"An existing bridge has a normal size extra space: 1x4 on each side"
so yes, pwp's which are built AFTER building the bridge are able to be closer.

edit: i made the guide more clear about the differences between pre and post building!

 

[jokimori]

are there more people who have bridge info...?

 

[Ras]

Based on this guide, I think I could take out the bridge near my cafe and be okay (I'd have to remove a streetlight), because the cafe does start the fourth square from the bridge, but it's one space north of your red square. Still, I don't think I'll risk it. I've got the cobblestone bridge there and I can live with it.

Actually, it looks like I could also take out the vertical bridge by my police station. Again, I don't think I'll risk it.

This thread smells of dissertation.

 

[LambdaDelta]

The only thing I'm getting out of this was that whoever decided the coding or whatever for how the no-build zones for bridges work either doesn't know **** about how to do that in a sensible way or was laughing their ass off the entire time.

I'm guessing the former. Since from what we know I think its simply that the game will detect if a PWP/building is closeby when trying to build a bridge, but not if a bridge is nearby when trying to set up any PWP/move-in. Which that's just straight-up bad game design imo, as shown simply by how much of a horrifying mess bridge construction can be.

Really though it should of just been done one of 2 ways:

a) building close to river is b& always, so a bridge can be placed in pretty much any location
b) no-build zone for bridges stayed consistently the same before and after construction

...or I guess you could combine these, but something about that seems a tad overkill to me. lol

personally i really like the cobblestone bridge because it matches with the plaza and other permanent pavements 'v' hehe anyway

my vertical bridge rules are made from assumptions so yeah be careful with that one!!!!

haha well most guides do almost, no?

yeah one of those would be a lot more convenient.... i don't want to think too long about the "why??" it gives me a headache hah...

I'll put your theory to the test soon. Luckily there are no houses near the place I want to build.

A guide like this is just what i've been hoping for! But I still have a few questions regarding how it'd work out for my planned demolition.. (i hope this is ok to ask here..)

i've been dreading trying my hand at destroying/rebuilding a bridge that Flora decided to move close to. I just can't be sure if when i destroy the bridge, that i'll be able to build another in the same spot, and i NEED it to go in the exact same area

XXX = Flora's house

(a crudely colored version for the imaginatively impaired ^^;; pls pardon the horrible highlighter coloring haha)


as you can (hopefully) see, Flora's house is 3 spaces away, with the extra space for her door one space up from the path of the bridge. If I were to destroy the bridge, do any of you think (based on the guide up above) if I'd be able to rebuild it??

edit: ugh the text-map isn't exact, so i'll post a screenshot :X

hi yourlilemogirl!

yes, of course it's okay to ask here!
if i apply my guide to your situation, you seem a bit unlucky :<
i drew it out for you:

Spoiler

the pink blocks are the current extra space of the bridge. the red/yellow dashed line is the extra space that will be needed when you're placing the bridge on this same spot. as you can see, the extra space of flora's house is in this area with 5 tiles! if you were to place the bridge 2 tiles more down south, it would work, but on this spot i would say it wouldn't!

i hope that helped!

you're welcome! this is a very frustrating part of the game, so i just needed to clear things up.
