Road & Highway

Design. Innovate. Deliver.


Parsons has engineered and constructed more than 10,000 miles of roads in more than 40 countries on six continents. Our road and highway projects circle the globe, through crowded cities and empty deserts, across rivers, and over mountains. Our technical capabilities, coupled with our construction capabilities and financial strength, allow us to deliver infrastructure solutions on many of the world’s most complex construction programs and projects that incorporate sustainability and resiliency to meet the changing demands of today and the innovation for the future.  

Parsons’ services go beyond expert planning, design, development, and construction of urban, rural, and special-purpose roads and highways. Our team also provides solutions on the impact of traffic, navigating the environmental process, asset management, construction engineering and constructability, technical concepts and modeling, as well as technology-enabled solutions like intelligent transportation systems (ITS) and drone-assisted inspection. 

As an integrated solutions provider, we serve as an industry leader and true design-builder to deliver projects using  alternative project delivery methods, including design-build, public private partnerships (P3s), and design-build-operate-finance-maintain (DBOFM).
