This is a 120 m train bridge. I'm not sure how feasible it is in the real world as the train gets ever so close to those crossbeams...
This is an 80 m train bridge. I liked the idea of creating a bridge that was not visible from its surroundings, especially considering the number of mounts strongly suggesting the form the bridge should take.
This is an 80 m car bridge, two cars cross from either direction and a ship passes under the bridge. I built this bridge as cheaply as I could and consequently it is a little wobbly. Despite this, it is still slightly more expensive than the world record, but I don't think I can trim this particular design down any more. It is supposed to be a drawbridge, but I just made a "high bridge" to save money.
This is a 120 m bridge for cars. It is perhaps the definition of a "dirty" bridge. The deck cuts through the land, it is rather cheap, and it doesn't always work. Due to its wobbly nature, it will take several attempts to get the cars across (note their comic positioning in the "stress" image), it may help to let it settle first.
This is a 160m bridge for a train. Whilst the ride is rather bumpy, this is my relatively cheap and aesthetically pleasing solution.
This is a 160 m train bridge. This is my latest attempt, improving upon the other example of the bridge that was already uploaded. It wouldn't be the most comfortable ride for the train passengers but the stresses are relatively low, and nothing gets broken.
This is a 120 m train drawbridge. I quite like this bridge actually, it is simple, with clean lines, and smooth action, leaving a large channel for the cargo ship.
This is a 120m bridge for a train. I'm a fan of slanty towers which support parts of the bridge, and with appropriately spaced foundations on the left-hand side I was able to put a set in here. Because the cables were not strong enough to support the entire bridge, I built a mini-supporting section underneath the right-hand side. The part is perhaps not as elegantly designed as it could be, so I'll probably have a redesign at some point.
This is a 120 m bridge for trains with asymmetrical mounts. My previous uploaded attempt for this bridge was truly awful - although I have refined that style somewhat since. This is a new, cheaper, approach which uses cables to contain all of the structure beneath the deck.
This is a 320m steel bridge for a train. Nothing much to say about this one, as it's nothing particularly special...
