1. Overview

Manhattan Bridge facts

The Manhattan Bridge is a renowned suspension bridge spanning the East River that links the notable boroughs of Manhattan and Brooklyn in New York City. Notably, it figures as one of the trio of major suspension bridges constructed across the East River, accompanying the iconic Brooklyn and Williamsburg Bridges. When beholding the Manhattan Bridge, one’s gaze is also met with the impressive backdrop of the Manhattan skyline, featuring landmark spires like those of the Empire State and Chrysler Buildings.

2. Location of Manhattan Bridge

Engineering feats Manhattan Bridge

The Manhattan Bridge provides a pivotal connection, linking Downtown Manhattan to Downtown Brooklyn. It spans the gap across two bustling areas, securing passage between Canal Street in Manhattan and the Flatbush Avenue Extension in Brooklyn according to NYC Gov.

3. Construction Timeline

It was the last of the 3 suspension bridges to be built across the East River. The nearby Brooklyn Bridge was built first and completed in 1883, followed by the Williamsburg Bridge in 1903.

Construction of the Manhattan Bridge started in 1901 and the bridge officially opened for traffic on December 31, 1909.

4. It Was Supposed to Have a Different Name

Historical significance Manhattan Bridge

  • Intended Name: Initially deemed “Bridge Number 3”
  • Reason: It was the third of its kind over the East River
  • Change Occurred: Renamed to “Manhattan Bridge” in 1902
  • Decision by: The overseeing construction board

Knowing it was almost called “Bridge Number 3” adds a layer of trivia that fascinates me. The decision to name it the Manhattan Bridge feels more personal, more connected to its identity and the borough it serves.

5. The New York Times Didn’t Approve of the Moniker

Manhattan Bridge construction details

The New York Times had a distinct perspective on naming the bridge. They felt the chosen name fell short in significance, suggesting instead a name connected to the bridge’s location, offering “Wallabout Bridge” as an option – alluding to Wallabout Bay to give it a sense of historical and geographical context. They argued that since every bridge spans the East River, the title “Manhattan Bridge” lacked distinctiveness.

6. Engineer Behind the Manhattan Bridge

  • Nationality: Immigrant from Latvia
  • Name: Leon Solomon Moisseiff
  • Education: Graduated with a civil engineering degree from Columbia University in 1895
  • Achievement: Regarded as a top authority on suspension bridges in the early 20th century
  • Notable Works: Manhattan Bridge showcased his expertise
  • Later Career: Career tarnished by the Tacoma Narrows Bridge collapse in 1940
  • Death: Suffered a heart attack three years post-Tacoma disaster according to Dokumen.pub

7. Financial Shortfalls

Impact of Manhattan Bridge

Construction efforts for the Manhattan Bridge began in 1901, focusing first on the tower foundations with active progress by 1903. Fast forward to 1908, the initial allocation of $10 million proved to be insufficient as it covered less than half of the necessary expenses. Eventually, they utilized a total sum of $31 million to complete the bridge according to Study.com.

  • Foundation Start: 1901
  • Active Construction on Caissons: 1903
  • Initial Budget: $10 million
  • Final Cost: $31 million

Budget Overrun:

  • Original budget fell short
  • Additional $22 million required

8. Pioneering Journey Across the Bridge

Structural engineering Manhattan Bridge

100 of the most notable citizens of Brooklyn were allowed to be the first people to ever cross Manhattan Bridge. This happened on December 5, 1909 as per Hotels.com.

This event marked the “unofficial opening” of Manhattan Bridge, which was followed on December 31, 1909, with the official opening by outgoing Mayor George B. McClellan Jr.

Imagining the first group of Brooklyn’s notable citizens crossing in 1909 gives me a sense of connection to those early moments of anticipation and pride. It must have been a remarkable sight, signaling a new era of connectivity.

9. Stabilizing the Manhattan Bridge

Manhattan Bridge infrastructure

  • 1907: Decision taken to add subway tracks to the Manhattan Bridge.
  • March 1908: Start of construction for railway tracks.
  • 1917: Completion of the track installation and the onset of stability issues due to the subway trains’ weight causing the bridge to tilt laterally.
  • 1956: Completion of structural modifications that corrected the tilting issue.

The incorporation of the subway tracks significantly challenged the bridge’s equilibrium, necessitating important modifications for consistent stability across the span.

10. Significant Renovation Expenditure

Manhattan Bridge architectural details

  • Duration: Spanned over 12 years.
  • Completed: In 2004.
  • Expenses: Exceeded $800 million USD.
  • Necessity: The bridge was no longer accommodating heavy vehicles on its lower deck due to structural concerns.
  • Objective: Undertake extensive refurbishments to restore the bridge’s integrity.

11. It Has a Structural Flaw in the Design

Unique features Manhattan Bridge

When visiting the bridge, you might have felt a noticeable sway, a testament to an engineering oversight during its construction. This flaw stems from additional expansions that weren’t part of the original design, including seven external lanes and four subway tracks.

As trains travel in parallel, the bridge experiences a significant dip, oscillating four feet towards the south and then four feet to the north, resulting in a total deflection of eight feet.

12. The Original Color was Grey

Manhattan Bridge design elements

Originally cloaked in grey, the bridge today is celebrated for its striking blue appearance, a hue that resonates deeply with admirers. This transformation to blue was not merely aesthetic but a homage to the Dutch tiles, a significant element of cultural heritage showcased at the Metropolitan Museum of Art. Furthermore, blue, as the official color of the borough, was chosen to symbolize Manhattan, imbuing the bridge with a sense of identity and belonging.

13. Design Shifts Due to Political Influence

Manhattan Bridge innovations

The bridge’s construction journey was notably impacted by the political landscape of the time, with ambitions leading to significant alterations in its design. The influential New York City Art Commission of the era played a pivotal role, turning down numerous designs they deemed unsuitable, reflecting how political dynamics can shape the architectural landmarks of a city.

The influence of political ambitions and the New York City Art Commission on its design is a fascinating glimpse into the interplay between politics, art, and engineering. It’s a reminder that the city’s infrastructure is as much a product of its cultural and political context as it is of its physical landscape.
