FIU Bridge Update - New Bridge Has Broken Ground

LittleInch said:

That will be a pedestrian bridge two people wide with supports every 40 or 50ft.

This is close to a road bridge with a significant span, plus two sets of lifts either end. They will be $2M each without any effort.

I was incorrectly assuming a mid-span pier placed in the median strip. I see that that won't work. So, a single 200' span instead of two 100'.

I'm not following your comment about "two sets of lifts at either end". What is that? And what does it have to do with the price of the bridge? "They" will be $2M...?

This site:


shows a price of $250,000 for a 100' highway span. I will speculate that a 200' span will experience a "cubed" cost--a cost increase of 9 fold. The cost then increases to $2.25 million. However, since this is for a highway bridge, I will cut the cost in half for a pedestrian bridge.

So I come up with a cost for the bridge of $1.3 million.

Lifts = Elevators

Oh.

There is not utmost clarity in the costs related to the fallen bridge. Wikipedia shows the bridge costing $9 million, and the overall project $14.2 million. The bridge is the thingy that spans a distance. Abutments hold it up, and COULD be considered part of the bridge. Elevators are not part of the bridge, just as approach ramps for roadways are not.
