Bridges and Tunnels in New York City - Tunnels

Tunnels

Each of the tunnels that run underneath the East and Hudson rivers were marvels of engineering when first constructed. The Holland Tunnel is the oldest of the vehicular tunnels, opening to great fanfare in 1927 as the first mechanically ventilated underwater tunnel. The Queens Midtown Tunnel was opened in 1940 to relieve the congestion on the city's bridges. Each of its tubes were designed 1½ feet wider than the Holland Tunnel in order to accommodate the wider cars of the period. When the Hugh L. Carey Tunnel opened in 1950 as the Brooklyn-Battery Tunnel, it was the longest continuous underwater vehicular tunnel in the world, a title which it still holds. The Lincoln Tunnel has three tubes linking midtown Manhattan to New Jersey, a configuration which provides the flexibility to provide four lanes in one direction during rush-hour or three lanes in each direction.

All four underwater road tunnels were built by Ole Singstad: the Holland Tunnel's original chief engineer Clifford Milburn Holland died, as did his successor, Milton H. Freeman, after which Singstad became chief engineer, finishing the Holland Tunnel and then building the remaining tunnels.
