This looks pretty cool: Through May, the Moline Public Library will offer a “VR experience” of the old and new I-74 Mississippi River bridges. (Story: WQAD) The library’s promotion of the “unique, immersive experience” made possible by collaboration between the Iowa DOT and Iowa State University’s Institute for Transportation also goes below the waterline, offering a look at the wildlife and ecosystem of the river.
The old bridge view cuts off at the ends of the bridges themselves, so you can’t see how the alignments will integrate. However, it’s a great tool for preservation of what those old bridges looked like after they’re demolished.
The Moline library is on 41st Street north; from Iowa, it looks like the best way is to exit at Avenue of the Cities, then go east, then south.
Also of note for I-74: The “first very, very large concrete pour” for a concrete pedestal — nearly 1000 cubic yards — was made Feb. 15.
