Featured web-links 2 - Wonders of World Engineering

Discovered this when doing a bit of background research on the Birkenhead Tunnel. Wonders of World Engineering is a Thirties magazine/part-work which someone has taken the trouble to put on the Web in DjVu format (need to download the DjVu plug-in to read these).

As well as a great article on the Mersey Tunnel there are lots of other well researched features related to roads and cars - for example, on the design and construction of the early German Autobahns.
