morning guys this morning I'm still working hard on the technology that can work for megacity bridge. my first thought was concrete than I realised that with the staircase width and breadth on the south, cost can be a problem so at the moment I'm considering I beans, a bit of concrete scattered where necessarily and laminated wood cladding to enhance the  exterior as shown on my sketchup drawing as a solution to cost efficiency. maybe by the end of 2moro the design will be done and and all the precedent studies will be allocated. have a nice day
