Bipartisan Infrastructure Law
We received $3.4 billion to invest in our nation’s infrastructure and competitiveness. The law provides funding for LPOE modernization projects that will create new good-paying jobs, bolster safety and security, and make our economy more resilient to supply chain challenges — all while serving as models for sustainability and innovation.
Sustainability opportunities
We will increase energy and water efficiency (including renewable energy and fossil fuel free measures), adhere to sustainable design principles, and minimize climate risk liabilities above the minimum performance criteria in a manner that is life cycle cost-effective.
- Net-zero ready
- 80% fossil fuel-energy generated reduction
- Green Proving Ground technology
- LEED Gold/SITES Silver
- Whole-building embodied carbon reduction
Community impact
We will fully modernize the port with a new administration building, new pedestrian processing lanes, new primary building, new passenger vehicle lanes, and new commercial vehicle inspection area. The project will help improve traffic flow and border security while decreasing wait times for travelers.
