So there are lots of options. One, if the bridge is still good for 40, 50 years, and this option is cheaper, you lower the road passing under to maintain clearances, and build huge beams across the road, which then you run beams under the bridges to support where is currently supported by the pillars. Can save money by supporting the pillar in the median too, but didn't draw that.Or could support the entire enterprise from a middle pillar.




Or you rebuild the bridge.



Or you just leave the pillars. Sure there are reasons to remove them, but are the reasons worth $10, 20, 30 million? I don't think so.
