Geometric and roadside design

Standard plates, design guides and quality assurance testing guidelines.


Geometric and roadside design is the blueprint for our roads. It's not just about making them look good but also making them safe and efficient for everyone. Engineers use geometric and roadside design to figure out how the roads should curve, how wide they should be, and how steep they can be. It is key to creating roads that work well for us now and in the future, plus making our communities safer and more connected.
