N Scale ancient river/road bridge scratch built from card for my N Gauge model layout

In this video I show the mistakes I made and the lessons I learned from the build. 00:00 Introduction 00:50 The basic structure 02:50 The 45 degree slice 03:41 Arch linings 05:14 Arch edging stones 05:52 The road bed 07:17 Buttresses and walls 08:18 The starlings 10:14 Finishing it off #NGauge #ScratchBuild #Card Bridge photo: Chemical Engineer / CC BY-SA (https://creativecommons.org/licenses/by-sa/4.0)
