Road & Highway

Leading the way


Parsons has engineered 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. With such achievements, it’s no surprise that we have been a respected leader in developing and implementing highway systems since 1919. Our technical capabilities, coupled with our financial strength and bonding capacity, allow us to partner on the world’s most complex construction programs and projects in order to meet the requirements of our customers, which include states, counties, cities, federal administrations, government municipalities, and highway/transportation associations and districts.
