Wheels of steel, rolling on wood: pole roads from the history of logging

If you're looking around historic logging regions, you might come across trucks, trains or even just axles with strange, wide steel wheels. They weren't intended to run on very large tires, but pole roads for logging. Here are some trains designed for such log roads, and here's a history of logging trucks that includes three types of wooden roads used to improve logging access. Here's a short clip of a logging train running on an elevated log track, and if you're thinking about building your own log road, The Timberman provides a lot of details and some schematics (Google books), straight out of 1918.

Getting a buzz on while you drive

Heading out for a drive this weekend? Live near Lake Biwa in Japan? Then head over the O-hashi ('Big Bridge') and sing along with the music your car will make as it runs over the 'Melody Road'. These attractions (distractions?) - created by carving ridges into the surface of the road, causing your tires to play 'music' - have popped up all over Japan in recent years (here's an English-language news clip on the phenomenon). But if you are a road engineer, and are thinking of perhaps making one of these, you had better do the math properly, something the engineers on a similar project for a Honda commercial spectacularly failed to do. (Analysis of what went wrong on this interesting blog post).
