One of the highest railroad bridges in America was built to carry Southern's relocated CNO& TP line across the New River in Project IV just south of Helenwood, Tenn.

This New River bridge is 307 feet, 5 inches high from average stream bed to rail top.

Nearly 15,000 cubic yards of concrete was poured for the giant piers supporting the more than four million pounds of steel which leaps 1,618 feet across the New River Valley at this point.

This bridge opened for traffic at 12:05 a.m. July 10.

That was when the past with its limitations be- came only a memory along the CNO&TP. At that minute, the future bowed in.
