New Bridge Replacement Technology (WI)

[knight1fox3]

An overpass near where I live (WI) is being replaced using some new technology I thought was pretty neat. So i thought i would share. Also wondering if this method has been used in any other areas of the US and if any civils on this board have been involved. Basically the bridge sections are being built remotely nearby rather than in place. Once they are done, the sections will be put into place by what's called a Self-Propelled Modular Transporter. A SPMT is a motorized vehicle that can pivot 360 degrees and lift and carry heavy loads. I imagine that has to be quite a considerable load. Anyway, more details at the link below for anyone that is interested.

I think they are using something similar around here. they posted a notice saying part of the interstate was being shut down over this past weekend to install part of the new overpass and how is was ordered and built elsewhere to be installed during that closure.

14 bridges in 10 weeks.

There is an FWHA manual and it seems to be the future for most federally funded bridge projects with a few of the State DOTs leading the way. Bridges are being built like Lego nowadays with high strength grout bonding this prefab pieces together after they are set on site. Cool stuff.

Sounds like they're describing a Goldhofer? We use those constantly for big components in new construction, i.e. module sections, large duct sections, turbine components, etc. Big sucker, tons of wheels along both sides, and typically steered/driven with a walk behind controller.

We (TDOT) did something similar on two bridges on I-24 in downtown Nashville. Every weekend last summer, shut the road down on Friday night and remove a few sections of the old bridge, drop in the new ones, open by Monday rush hour. Went pretty smooth, finished 1 week early if I remember correctly.

That's pretty rad. Thanks for sharing k1f3.

The bridge replacement was a success. Looks like the actual event over the weekend drew a bit of a crowd including some out-of-state folks. More on that story below. If interested, they also show a brief time-lapse video of one section being moved into place.
