MTJ Roundabout Engineering has extensive experience designing complex, closely-spaced multi-lane roundabout interchanges.
MTJ Roundabout Engineering was responsible for the capacity analysis and horizontal design of what was the most complex system of roundabouts in the US at the time, the US-23/Lee Road roundabout project, which opened in 2006.
The US-23/Lee Road roundabout project is the winner of the 2008 Eminent Conceptor Award for engineering excellence from the American Council of Engineering Companies (ACEC) Michigan. This successful public/private partnership is the highest category award of the Michigan competition, and evaluates projects on “complexity, innovation, client satisfaction, future value to the profession, and considerations for social, economic and sustainable design.”
