How do I build a bridge over a road?

[El Presidente]

Nothing I try seems to work. I have tried rasing and lowering the land. I have tried the M & N keys. I have tried making the RR long to give it more to work with. It always says terrain alighnment collision. There are no objects nearby so why can't I build a bridge. Bridge building in TF was hard enough but TpF seems to be almost impossible.

I manage to get it to work after about 30 tries!

The earth works on the left looks terrible. Luckely I have a tree brush that can hide most of the eye sore.

Pateints dude. While you were typing this I was figuring it out and taking a screeny I don't remember what I did but after about 30 tries I got lucky... Sort of.

[Metacritical]

in that context i would have deleted the road built the rail line and then bridged the road instead.

I didn't want the food service to slowdown.

I think the bridge you made looks fine. If the steep land supporting the rail on either side looks ugly to you than simply using the terrain tool you can raise and level it all out so that there is barely any noticeable slope at all.

Well, good luck my son, wait until you want to build complex bridges across rivers and merge tracks at height...

Building a train bridge over a road is expensive because you need a LONG runup to have the climb and decent shallow enough for trains.

You wouldn't have if you paused the game. I'm with Metacritical on this.
Delete road, build track, rebuild road with bridge over track, unpause game.
Probably the cheapest way to go anyway.
(Worrying about the food service being slowed when you're using trucks doesn't quite make sense when you think about it.)

To avoid any interuption of the road vehicles using the road it is imporatant that there is a detour for them to take before deleting any road. If there isn't already a detour than you can create one, then pause, make your changes and then delete the detour. You can create and delete the detour all while paused if you like.

If a detour is not made before deleting the road than the line has no path to recalculate and all the vehicles on the route that were presently heading to the stop on the opposite side of the road you deleted will turn around and head back to their previous stop even if you rebuilt the road before unpausing. This is not the case with trains for some reason. Only road vehicles.

Regarding my previous post I thought it might be helpfull to illustrate my suggestion I made with some screenshots, in case my explanation was inadequate. I made two bridges just to show an alternative way of doing it that would cost less and create less incline overall. The bridge on the left is representing the bridge you made while the bridge on the right is a compromise between partially lowering the road and partially raising the rail.

I'm confused.
If you wait till the vehicles are out of the way before pausing the game and making changes, why do you need a "detour"? You'd only need a detour if you didn't pause the game.
The worse that can happen is the road is too conjested and some trucks will have move a few feet back for construction while paused. In the grand scheme of things, that's no big deal.
(Don't detours cost extra money?)

Default bridges are easy. Make sure you have enough run up and build the road over the thing you want to cross. Then hit m key to raise until it creates a bridge. If it doesn't, then you have not done enough run up. I cannot stand the hump bridges that the game likes to build by default though so I do it differently. I raise a bit of the terrain on each side to around 12 metres higher then the level of the ground I am trying to bridge. I can't remember the exact number, but the game does not like low bridges unfortunately so it needs to be at least around 10-12 metres, iirc. Then you can build a road, or rail, straight across from the hump. A hump on either side does make it easier, but some times not necessary, as long as you set the elevation to go directly level and not hug the terrain. This way you will have a perfectly flat bridge bit and you can choose how long to make the approach and therefore the slope of it too.

There are hundreds of vides on youtube that can help, if you cannot figure out basic game mechanics by the way.

The reason why the bridge isn't looking that great is because your highest point isn't over the road.
Raise a piece of track to maximum steepness some distance from the road/track you want to cross. Then flatten out the track and see if if wants to form a bridge near the track/road you're crossing.
Than build the piece just past the road/track.
Than it's simlply going down from there and your highest point will be over the road/track, creating a (somewhat) realistic looking bridge.

@el preseidente The reason that particular bridge was difficult for you to make is because the track ramp is on the side of a hill. Turn on the gradient lines and you will see this. I can tell from your picture because the ramp on one side is much small than the ramp on the other side.

Most the excellent suggestions on this thread will have some trouble because you are trying to elevate a track to a bridge ramp while going uphill (the left side of your picture). If everything had been flat, I doubt you would have had any problems.

The best solution for this setup is to delete the road, draw the track, it's already running uphill and you don't want to add any more incline. Then bridge the road over the track. This would be easy because as the road's direction is flat, relative to the tracks, the M & N adjustement would work fine.

Vimpsters suggestion of lowering the road will also work, but gets a little more challenging because of the slop the tracks. For that you will need to drop the road low enough to not add any more slop to the track heading up the hill.

As for messing up the food truck line, don't worry about it. Pause, build, make sure all roads reconnected (truck lines are displayed correct) the take game off Pause. If you don't want to use Pause, then build a detour route path first.

[Vimpster]

Perhaps you guys have not paid close enough attention to what the trucks (or any player owned road vehicle) does when you delete a road it is using and there is no alternate path. To be clear, the detour is needed whether you pause or not to avoid any interuption. The detour never has to actually be used by any vehicles. The detour is purely for the line itself to recalculate a new path. making a detour generally does not cost much at all. I make detours every time I am about to delete a road segment that I have vehicles useing.

If you don't care that some of your vehicles (all vehicles heading towards the break in the road at the time) will get turned around and head all the way back to their previous station than it does not matter.

I would suggest putting the road over the railroad. That is a much easier thing to do.
