Skanska's Bridge Project: Innovative Dehumidification for the Verrazzano-Narrows Bridge

On August 19, 2025, Skanska announced its successful bid for an ambitious project under the Metropolitan Transportation Authority (MTA) to implement a dehumidification system for the main cables of the iconic Verrazzano-Narrows Bridge in New York. The contract, valued at a staggering USD 249 million (approximately SEK 2.5 billion), represents a significant advancement in maintaining and enhancing the longevity of this crucial infrastructure.

Project Overview

The primary goal of the project is to design and install an advanced dehumidification system on all four cables of the Verrazzano-Narrows Bridge. The necessity of this system arises from the need to manage humidity levels, which can significantly affect the cables' integrity over time. In conjunction with this installation, Skanska will also integrate an acoustic monitoring system on each cable to ensure ongoing assessment of the cables' condition and performance.

This project scope is not limited to just dehumidification technology; it also includes the upkeep of associated electrical and communication systems. Skanska is tasked with ensuring the maintenance and monitoring of these systems for a period of five years after their commissioning, ensuring that the infrastructure remains in peak condition.

In addition to the main tasks, the project will involve several critical supplementary activities. This will include facilitating internal inspections of the cables’ main panels, replacing all cable band bolts, as well as upgrading aerial obstruction lights and supports, messenger cables, hand ropes, and stanchions. These activities indicate Skanska’s commitment to ensuring not just the immediate effectiveness of the new systems but also a thorough maintenance regime for the future.

Project Timeline

The contract was officially awarded in July 2025, signaling the start of a complex project that is expected to be finalized by September 2029. This timeline accounts for the meticulous planning and execution required to carry such a significant operation, underscoring the project’s extensive requirements in both engineering and stabilization of a critical part of New York City's transit infrastructure.

Significance of the Project

The Verrazzano-Narrows Bridge is not only a vital transportation link, but it also stands as a landmark representing New York's engineering prowess. The dehumidification system promises to extend the life of the bridge’s main cables, thus contributing to the overall safety and reliability of this essential crossing. Given the historical significance and the ongoing wear and tear that structures of this magnitude undergo, Skanska’s project is a forward-thinking approach to maintaining such critical infrastructure.

By leveraging advanced technology and procedures, Skanska is setting a standard for future infrastructure projects. The use of acoustic monitoring in conjunction with dehumidification stands as an innovative technological approach that could potentially inspire similar projects across the globe.
