The section of viaduct on the windward side between the little cut-and-cover tunnels and the big boy tunnels is just a mile long, but it was built under a 136 million dollar contract.
A gust of wind that blew in at the window ruffled the cloth on the table, and in the square below all the great caps of the peasant women were uplifted by it like the wings of white butterflies fluttering.
The tunnel entrance on the leeward side stands 1,385 feet above sea level, most of an Empire State Building, while the entrance on the windward side is 840 feet above sea level, less of an Empire State Building.
