Bridge+Builders

What is involved in the construction:__** Workers, plate weldings, money, permission to build the bridge, heavy duty equipment, and concrete will be involved in this construction, welding tools, metal fencing, metal suport beams, rail gaurdes, lighting for pedestrians and trains. We're also going to need some sort of device to most people in wheelchairs across the bridge. we the 5th period class think that in the construction there should be an elevater added for the disabled, and stairs for the rest of us.Of coarse there will still be a cage like structure around the bridge so no suicides are attempted or so no one falls off.

With this, there won't be any deaths regarding the trains. Also, the train station will not be sued for injuries caused by the train and if we were to do something underground the tunnel could colapse when the train comes. Also if it rains the tunnel would flood unless we built a drainage system which would take time and money, not to mention would take too long to drain the water out, closing the tunnels. And, even though it might be exposed by the elements, will have a closed top, and will not erode very fast due to material.
 * __Why this is the best solution:__**

It will be used over the railroad tracks at North Oaks Middle School as well as all over the world. Some of the places this idea is being used are at West 173rd Street,Fort Washington Park,in New york there is a Pedestrian Bridge over Amtrak Railroad Tracks. If you go to ([]) it would show you some places where they use bridges.
 * __Where it is being used:__**

__**wheel chair access:**__ We will make it half a ramp or an elevator like device for the wheelchair bound people and strollers, the other half stairs for the people who are walking. It will be like the stair ramps in the North East Mall and at the stairs at North Oaks Middle school. These are some pictures of other bridges:

__**Data on trains:**__

Trains are 6.1 feet tall, so the bridge will have to be atleast 10 feet. That way if anything on the train is sticking out it will not hit the bridge.

Mrs. Bland has asked use to make a list of materials for a modle of the bridge. it will be but on a a large board showing the school and the train tracks and the libary. and we will put the bridge on it and show how it will be used.

Next week we will be working on model of the bridge and finding how tall we will need to make the bridge.
