Transportation systems are the backbone of our nation's infrastructure. Without them, we couldn't provide even the most basic services to our communities. This puts transportation improvements at the forefront of infrastructure maintenance. At 21 Design Group we understand the importance of not only safe, reliable roadways but also the importance of safe, reliable, ADA accessible pedestrian pathways. As the most visible component of our infrastructure, it is imperative that we continually upgrade our transportation systems with an innovative approach. Innovative design is at the core of the 21 Design Group principles.
