MnDOT’s New Bridge Construction ‘Slide’
We've always said there are two season in Minnesota: Winter and road construction, right? So, I'm for any way MnDOT can actually speed up construction projects across the Land of 10,000 Lakes. One way is a new method of constructing bridges-- and according to MnDOT, they're using the 'slide' bridge deck technique on the Larpenteur Avenue bridge in St. Paul.
While I'm not an engineer, BringMeTheNews says the process involves building a new bridge deck only a few feet from the existing bridge, then using massive hydraulic jacks to 'slide' the new deck into place.
According to the Bring Me The News, "MnDOT says the big plus for using the technique comes with the amount of time – and money – saved on construction. “Doing this bridge under conventional methods, the closure would be about 110 days,” project manager Dave Herzog told KSTP. “With the method we’re using here, we’re going to get it completed and open in about 47 days."
