Build a 3D Overpass Bridge in 3 Minutes

The pattern sheet is on page 2~ The whole thing only uses the straight line tool, and can be done with just two colors — white and gray! First, choose to create a cube shape. You only need to draw four faces, and every stroke can be made by dragging with the straight line tool. For the steel beam parts, you can draw one side and then directly copy and flip it to the other side to make both sides symmetrical~ For the top, you only need to draw the outline of the bottom horizontal bar, then use the straight line tool on the front face to draw the support beams. Finally, squish the overall size down as flat as possible — refer to page 2 for specifics. When doing island design, leave three grid spaces of width for the bridge deck. Place the finished overpass in the middle grid space (refer to page 3), then rotate it, copy it, and place another one — and you're done~ There's also a simple little car tutorial included on page 3, feel free to check that out too~ Hope this helps everyone!
