Mr. Holland’s Tunnel

J.M. Syken

Course Outline

In this course, we will examine the historical background, design, construction, operation and legacy of the world’s first mechanically ventilated vehicular tunnel, spanning the Hudson River between lower Manhattan and Jersey City, New Jersey. This review will include the debate concerning whether a bridge or tunnel would be most appropriate and the two state commissions created to study the problem, need, financing, capacity etc. The choice to build twin tubes, alternate tunnel designs, the “coal famine” of 1918 (which dramatized the need for a vehicular river crossing) will be highlighted as well. The “Shield Method” of tunneling used to dig the tunnel will be reviewed in-depth and detail.

The role of Chief Engineer Clifford M. Holland in the design, construction and posthumous naming of the tunnel (in his honor) will be reviewed as will be his two successors’ accomplishments. In particular, the role of Ole Singstad, the tunnel’s Design Engineer who took on the role of Chief Engineer (after Holland’s and M.H. Freeman’s untimely death/s) and completed the tunnel, going on to become one of the greatest tunnel engineers of the era. The design, testing, equipment, installations, operations etc. of the mechanical ventilation system designed by Singstad will be of great interest. The success of the tunnel and plans to make it part of Robert Moses’ Lower Manhattan Expressway project (never realized) will also be of interest.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.

Course Summary

In January 1918, lighters carrying coal destined to heat homes and businesses on the island of Manhattan were ice-bound in a frozen Hudson River. That very cold winter and the inability for the coal – within site across the river - to get across dramatized to all concerned the need for a vehicular crossing of the Hudson. The two states on either side of the river; New York and New Jersey, began looking into a trans-Hudson crossing in 1906, at first favoring a bridge. By 1913, a tunnel with adequate capacity (via twin mono-directional tubes) and a revolutionary mechanical ventilation system (to remove the deadly carbon monoxide) was decided upon. The project was delayed, mainly due to WWI, but by 1919 Chief Engineer Clifford M. Holland was given the green light to proceed. He gave the work his all - including his own life, dying of heart failure in 1924 before his great work was completed (in 1927). To honor his heroic effort, the tunnel was posthumously named in his honor (not as a reminder of NYC’s Dutch heritage, as some mistakenly believe). The tunnel set the gold standard for ventilated vehicular tunnel design still used today. A financial and commercial success, in its wake came more tunnels (and bridges) to break the water barrier that had isolated Manhattan from the rest of the nation.
