Normal level 13
« on: December 19, 2001, 04:22:10 PM »
I cannot for the life of me get a bridge to work.
I can get about 1/3 of the bridge supported by putting triangle supports underneath (using the mounting in the water), and about two segments or so supported using suspension-bridge type stuff on the right side. But this is no good. I tried putting lots of triangles (including using the middle dimension) all the way across to support, but there is problem with compression on the far left because of the rising land there stopping me from putting additional bracing. Also having problems with the budget, I can't go too crazy with tons of bracing to keep it up.

Besides, I don't think it would support the entire bridge ':)'

I've never had any success building bridge "arches" or anything, perhaps this would be a better solution? I looked at one of the poster's website where he had pictures of all his 'solutions', but he just had a default suspension bridge for 13, and when I built it it barely held together with no train. With train, she went down pretty hard.

Please somebody give me some hints, its causing me headaches ':)' (It took me like two hours to finish level 12, BTW. I was pretty thrilled to finally get 0 breakage on that one, lemme tell ya)

I'm not quite sure how to post a picture but I'll do my best to describe how my bridge was built.

This bridge can be built using the low density grid.

Start by laying flat deck across the span at the regular intervals. Once the deck is laid start building HEAVY STEEL from the submerged anchor (going to the right) at a slope at a slope of 2/4, or up 2 over 4 (generic low density blocks). Build 3 of those beams, and then lower the slope to 1/4, and then once more to a flat beam, and then once more to a -1/4 slope beam, and then finaly connect to the other anchor point on the right side of the gap (this time using light steel).

You should now have the track laid with the heavy steel looking like an unbalanced arch. Going back to the left end of the bridge construct a vertical heavy steel beam that connects the anchor point to the first joint in the deck. Move over to the first joint in the heavy steel and repeat the process, this time building a beam to the second joint in the deck.

Almost done.

It's finaly time to support the arch. Like before create VERTICAL beams from the joints in the deck to the joints in the arch, but this time use light steel. The last 2 pieces are light steel and connect the 1st and 4th joint in the actual arch to the 6th and 7th joint (respectively)in the deck (assuming we're going from left to right).

Congatulations, the bridge is complete.

I didn't try to minimize the cost of the bridge (๪,462), but I'm sure you can manage to drop the price if you try. It breaks no links on hard. I hope I have not confused you but I would understand if you are. I hope this has been of some help.

Enjoy
