Parallel Cable-Stayed Bridge

This bridge is at the same time an experiment in building a parallel cable-stayed bridge, and an experiment in building a cable-stayed bridge only using LEGO.

Walk bridge

This bridge is located close to the City X'ers head quarters. The legs comes from the tower in the newest (in 1995) LEGO town airport.

• Walk bridge.

Cable-stayed bridge

This bridge is shown in three stages:

1. One tower ~ 1 meter deck
2. One tower ~ 2 meter deck
3. Two towers ~ 2 meter deck

My ambition is to build a cable-stayed bridge across my cousins' pool. That would be three to four meter free span.

Here's some of the mess in the living room while we were building.

• At the halfway point.
• Another view at the halfway point.
• Yet another view at the halfway point.
• The dining waggons.

• The long single tower bridge in our living room (I cleaned up before the photo was taken :-).
• Out in the garden - no load.
• From the north end.
• The construction site shows the two dining cars, the welding robot, floating crane and support boat.
• A closer look at the work at the south end. Notice the chef working on the floating crane.
• Welding the last section. My welding team is working from the floating crane and Morten's welding robot is working from the bridge.
• A close look at the bridge deck. Every section is 16 knobs long and 21 knobs wide.
• In the beginning of the construction work, there was a strike. The workers on the bridge deck wanted a place to eat, so we decided to get two dining cars.

• The two tower bridge (with my sister Katrine in the background - she didn't work on the bridges, but her restaurant profited from the work).
• The two tower bridge with load on the center part of the deck and with load on the south part of the deck for comparison.

Some of the train cars used while building the bridge.

Jungle bridge

There's only one shot of this bridge. Notice that some of the arms holding the railing are costum made.

Gitterbro

One morning I suddenly figured out how to build a simple bridge with a triangular construction. I had 1*8 plates to support 1008 mm bridge deck.

• Here's the bridge out in the green.
• A close view at the construction.
• From the north end.
• Spanning almost one meter.
