What are the biggest upcoming construction projects in the U.S.?
The biggest projects announced in 2026 include xAI’s $20 billion-plus data center in Southaven, Mississippi; Google’s data centers in Wyoming ($17 billion) and Missouri ($15 billion); SpaceX’s $16.8 billion-plus Terafab in Texas; and Mesabi Metallics’ $15 billion steel complex in Iowa. Dodge also counted 23 projects of $100 million or more entering planning in October 2026 alone.
What state has the most road construction?
Texas. Federal Highway Administration data show Texas spent $27.2 billion on state highways in 2024, including $15.8 billion in capital outlay, the most of any state. In August 2026, the Texas Department of Transportation adopted a 10-year plan with a projected $138 billion investment, including $95 billion for projects.
What are the new developments near me?
Start with your city or county planning commission agendas and building permit portal, which list proposed projects before they break ground. For commercial work, a verified project database lets you filter by county, project type, stage, and value, and shows a named contact and phone number for each project.
Which states have the most large construction projects?
On this list, Texas has the most, with four projects worth $1.5 billion or more, followed by New York, Louisiana, North Carolina, and Michigan. For a ranking of overall activity, Texas, Florida, and California led the U.S. in housing units permitted from January to September 2026.
