New York's Hell Gate Bridge carries Amtrak's Northeast Corridor high above the East River. The 1,017 foot span served as the inspiration for Sydney's Harbor Bridge and carried four tracks when opened in 1916. Soaring high over Astoria, the bridge's approaches give passengers headed north of Penn Station breathtaking views of Manhattan's skyline and the Triborough Bridge. It was completed in just two and a half years at a cost of $20 million (approximately $390 million in 2008 dollars).
