The 5 Most Impressive Infrastructure Projects of the YearSarah Zhang8/07/14 9:00amFiled to: collectioninfrastructurehalley vibay bridgesan franciscoantarctica344EditPromoteShare to KinjaToggle Conversation toolsGo to permalinkEach year, the American Society of Civil Engineers gives out an award to celebrate the sheer size and complexity and awesomeness of infrastructure projects built by Americans. From an Antarctic research station on hydraulic stilts to an flyover railroad crossing, this year's five finalists are truly remarkable. AdvertisementBuilding gigantic structures is not usually glamorous, but the ASCE's Outstanding Civil Engineering Achievement award will be announced at a black-tie gala in Arlington, VA, on March 26. For now, let's take a closer look at the contenders. Halley VI Research StationThe British Antarctic Survey's Halley VI Research Station looks like a brightly colored train-beast lumbering across the icy terrain. Indeed, Halley can move. On each of its "feet" are skis, so the entire whole station can be towed away by bulldozer. Halley VI has to be the first fully relocatable research station in the world because it sits on the Brunt Ice Shelf, which is slowly crumbling into the sea. On top those skis are hydraulic stilts that can lift the seven capsules up and over snow as it accumulates over winter. This is actually the sixth incarnation of Halley, and the first four were in fact buried and eventually crushed by snow. If Halley VI lives up to its promise, it will fare much better than its predecessors (though recent technical issues have put its future in jeopardy).
