Ten World Engineering Marvels-- Part 1: Panama Canal and Golden Gate Bridge

From the History.com site by Christopher Klein.

These remarkable feats of design and construction transformed the ways that people travel, communicate and live.

For thousands of years, mankind has engineered some remarkable structures such as the pyramids of Egypt and the Great Wall of China.  More recently, engineers have undertaken massive  transportation and communications projects  that have pushed the boundaries of human ingenuity.

I am just listing them and giving one or two facts about each.  The site has pictures and a lot more.

Here is a list of ten of them:

1.  PANAMA CANAL

52 miles long and opened in 1914

2.  GOLDEN GATE BRIDGE

1,7 miles long (was the longest suspension bridge for  27 years)  Opened in 1937.  It's been wiped out in more than a few disaster movies so don't drive on it when they are shooting a movie about San Francisco.
