Existing comment: Initial construction period (1902-1904):
The original plans for construction called for the 32 miles across the water to be a rock filled causeway. However, because of the lake's soft bottom and regular sinking of the fill, a 12 mile trestle was built west of Promontory Point using over 38,000 pilings with several being driven at 120 feet before they hit solid ground.
