You might want to look at the NMRA standards for clearance.
Have not looked at G Scale, but they have standards for everything else.

Scales Modeled: HO then G back to HO
I hope it's OK to post this information here.
I have been away from G scale for several months but there are several G scale forums you could try. Large Scale On Line aka My Large Scale, Aristocraft, and Large Scale Central. Google them and you will find great information. The problem is there is no standard G scale ratio as there are in other scales.

I think Navarre has it right. I would take a look at NMRA standard S-7 for the clearances.

I just looked at the NMRA S-7 Clearance Standards

Apparently Gramps is right. There are many different "Large Scale" sizes.

The NMRA lists the following:

1:20.3 scale, they are calling F Scale
1:22.5 scale, they call G Scale
1:29 scale, they list as a recognized scale but don't give it a scale name.
1:32 scale, they are calling No. 1 scale.

I think my Bachman trains are 1:22.5 scale (what I considered to be the standard for G-scale)

The G scale community refers to all those scales as G scale that run on #1 gauge(45MM) track.

That explains a lot. I just read the "G-Scale" page on Wikipedia and they explain a lot of how the different manufactures created the different scales but all used the same size track.

This is actually quite interesting for me.

I'm building an outdoor "G-scale" model railroad. And I actually think of the G as referring to "Garden Trains", since I'm basically building this around my landscaping gardens in my front yard.

In any case, I actually decided early on to build all my buildings, cars, and people using 1:32 scale models. I wanted to stick with a single scale for the main scenery and dioramas. I chose 1:32 scale for several reasons, one of which is because it will allow me to do what I want to do within the space of my gardens. A larger scale like say 1:24 would be a bit large for the area I have to work with.

My current trains are Bachman "Big Haulers" which are indeed 1:22.5 scale. But I'm hoping to eventually replace these trains with my own home-built trains. And I would actually like to build my trains in 1:32 scale to better match my dioramas.

Apparently I'll be able to do that and retain the same size track the whole way through. That's makes it really nice.

In the meantime I'll need to build this covered bridge large enough to accommodate my 1:22.5 trains.

If I put any up for sale I'll just say that they are 1:22.5 scale, and call out the actual dimensions. That way I won't need to worry about calling them "G-scale".

G scale is unlike all the others because of the different sizes. If you are modeling standard gauge then 1:32 is in proportion to the track size. 1:20 and 1:22 are roughly in proportion to some narrow gauges. 1:24 is half inch equals 1 foot and 1:29 is exactly 3 times HO. It gets really crazy when you try to find buildings and automobiles to match your size.

There is a Covered Bridge Museum in Bennington VT
Google Image "Covered Bridge" to get some ideas.

Just remember to count for your track height, around 1/2" tall
I would make it at least 10" tall and 8" wide, that way more of your work will be visible from the ends.
1/2" to a foot is an easy scale to model in. Anything close to that will work, This job would be much easier with a pinner, headless pinner prefered. only Grex makes 3/8" pins, so if you use 1/2" pins you will need to plan around pinning two pieces together.
Good luck and please post pictures
