I took off today to get some work done on the bridge. After cutting the curves out of plywood, I screwed them together to make the long curves.
Next, 2x4 s on 12 inch centers.
And then I covered it with 3/8 inch plywood.
This will be the form for the bottom of the arch bridge. I will have to make another form for the top. The idea is to pour 3 arches, each 4 feet wide. Then they will be placed side by side over the creek using a crane. The side arches will also each have a wall and will weigh about 19000 lbs.
Here is sort of a side view of the bridge. You can see the shape of the wall. The arch is the bottom circular part. Gravel will be used to fill in between the walls.
Brandon is flying in today and it looks like we will have nice weather. We plan to do some mountain bike riding and who knows what else.
