What was the sales growth rate in the Automotive segment in 2021
s we combine our capabilities, reapply our talent, and repurpose existing assets. This provides a powerful value creation lever by unlocking new ways to integrate more of our content into our customers' ecosystems. We aren't exclusively relying on people buying more stuff.
We're driving more Corning content into the products they're already buying. Our progress in 2021 illustrates the effectiveness of our approach, and it gives us confidence that we're building on a strong foundation for additional growth in 2022. In Optical Communications, we've returned to growth with sales up 22% in 2021. And we expect strong growth to continue.
Operators are expanding network capacity, capability, and access. The pace of data center construction is accelerating as more applications move to the cloud and data creation continues to soar. And fiber-rich wireless deployments are underway. Meanwhile, governments around the world are initiating plans to extend the reach of broadband to more people in more places as network access is increasingly viewed as a human right.
For example, the recently passed U.S. infrastructure bill allocates $65 billion in new spending for broadband infrastructure, including $42 billion for new network builds. Our customers are stating their preferences for fiber to build these networks. As the only large-scale end-to-end manufacturer of optical solutions, Corning plays a vital role in driving the continued expansion of connectivity.
We're working even more closely with industry players at the regional and national levels, including expanding our longtime collaboration with AT&T. Stepping back, we're at the beginning of a large, multiyear wave of growth for passive optical networks. Project momentum is strong across our customer base. And as U.S.
infrastructure plans roll out, it could add as much as $1 billion a year to the market for four years starting as early as 2023. We believe private carrier and public infrastructure investments will push the market into double-digit growth over the next few years. In Life Sciences, we're delivering growth on multiple fronts with sales up 24% in 2021. We're seeing ongoing demand in support of a global pandemic response.
Our inventions are also helping the industry advance the transition to cell- and gene-based therapies. And we're making progress on our multibillion-dollar content opportunity in our pharmaceutical packaging business. After introducing Valor Glass vials in 2017, we recently introduced Velocity Vials. These vials are helping industry-leading drugmakers increase efficiency and throughput to drive faster manufacturing of vaccines to help meet global demand.
Velocity joins Valor and our glass tubing business as we build a comprehensive end-to-end pharmaceutical packaging portfolio. In fact, our portfolio has enabled the delivery of nearly 5 billion doses of COVID-19 vaccines so far. And earlier this week, West Pharmaceutical Services, a global leader in injectable drug administration, announced a long-term supply agreement and technology investment in Corning to enhance injectable drug packaging systems. In automotive, 2021 sales in our Environmental Technologies segment increased 16% to reach an all-time high $1.6 billion despite weakness in the automotive market related to chip shortages.
We're pursuing a $100-per-car content opportunity driven by trends that are reshaping the auto industry and reimagining the car. We delivered multiple proof points in 2021. Daimler launched the Hyperscreen dashboard display in the Mercedes-Benz EQS. The display features a Gorilla Glass cover nearly five feet wide.
Building on this momentum, we entered a new automotive product category with our Curved Mirror Solutions. This innovation is enabling the augmented reality head-up display in Hyundai's electric crossover, the IONIQ 5. And Jeep announced a product that brings our tough technical glass into their iconic vehicles. The new Jeep performance parts windshield featuring Gorilla Glass is now a factory-installed option on the Wrangler and Gladiator.
