Yeah that sounds like a good idea until someone decides the line is too long and just lets it rip into the transporter.
Pedestrian Bridge
- Thread starter kludger
- Start date
Most roads, when built, are built above the base flood elevation so they don't wash out during floods. I would assume that this was why the road bed was built up, but I don't know. I do know that it was never intended to be a levee. It has been considered before (http://www.desmoinesregister.com/ar...-considers-levee-to-safeguard-Hilton-Coliseum), but it will likely never happen.
Air cannon, with a landing pad on the other side. Imagine the lines...
Oh, and not nearly the capital expense of a bridge!
So I really haven't read much of this thread, but basically we're going to be doing this (unless it's more of an Iowa City idea):

I think another flaw (of many many flaws) would be that the approach would have to be huge to go as high as it would need to be. It would have to be high enough for semis and buses ect. Approaches on these such as this have to be a certain pitch (dont know the appropriate terms) to meet minimum handicap rules ect to get wheelchairs up and down. This would put the start of the bridge at approximately the entrance to the student lot actually prob greater than that. On top of this there are 2 sides to the street so you would still have people crossing to get to the bridge. While it would be cool, it really isnt possible.
If my Monorail idea is cost prohibitive then we go cable cars that go way higher than necessary and drop you at the new SEZ.
I think people need to look up the definition of a levee. If the mound of soil prevents water from getting to the other side then its a levee. It doesn't have to be FEMA certified or built by the Army Corps to be a levee.
so does that mean im right or wrong? assuming the bottom of the bridge is 15 ft to accomodate a 14ft semi, and then add a foot on top of that for actual walking height so 16 ft.
If the walkway was 16 feet high the ramp would need to be 192 feet long. That's why you see either circle ramps (typically next to highways) or elevators (like in Vegas). I think the problem here is there is nothing nearby to architecturally tie-in the ramps. We would have a nice brick walkway but then a really long ramp or a windy circle to meet the 1/12 pitch. If I'm in a wheelchair I'd much rather wait and go flat across the street than go up and down a total of 384 feet.

So, then we build a parking ramp(s) on the east side of University (since we're snatching the intramural fields anyway), and stretch the walk(s) from those to the concourse level. Simple enough? :idea:
We'll need the extra parking with a sufficient expansion anyway.
This is Iowa State we can't get everyoneto wear a certain color. What makes you think you will get people (especially drunk students) to walk all the way up the stairs and then across and back down when they could just walk across. Hell you will probably have a few engineers fight with the cops over the added energy and how it could have been designed better.
Sounds like a great excuse to build our own Hovenring. Hovenring | Innovative Circular Cycle Bridge, The Netherlands

My only input is that if we're building a bridge, I hope for it to be grand and artistic and full of vigor....rather than be so...pedestrian.
This is a huge waste of money if only used 6 times a year. Plus, pedestrian bridges are generally ugly unless a lot of excess money is put into design and construction. Fix up the intersection and crosswalks with wide brick walking lanes and other decorative lighting/features and call it good.
