interesting landslide problem has developed on the AA1 motorway at Bucium Hill in the Transylvanian hills of in Romania.\u00a0 This section of road, was built between April 2011 and November 2014,\u00a0 In includes a very substantial cutting through Bucium Hill, with then transitions into a major viaduct, as seen below (via <a

2015 and October 2016.\u00a0 To deal with the problem the slope appears to have been successively regraded to a lower angle.\u00a0 The video below shows the site in September 2015 after substantial works on the north side of the road.<\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/3kLbZUuwLsw\" width=\"640\" height=\"360\" frameborder=\"0\"

2016 it appears that there has been considerable recent movement.\u00a0 There appear to be multiple types of landsliding occurring here.\u00a0 The most substantive movement appears to be occurring in
