When you work with us, you’re family. Whether you’re an employee or a client, we make you feel at home.


Accountability is key. If we make a mistake, we own it. Great things come from great communication.


Sticking to the standard quo is boring. We are always looking for bigger and better ways of getting things done.


We take great pride in our work. Passion is energy – and we bring it every day.

Who We Are

“We Get You Where You’re Going Safely”

We are a WBE & DBE heavy & highway business. Moving the heavy & highway industry forward since 1981. Your go-to Maintenance of Traffic experts.

Since our inception in 1981, we have strived to serve our community while advancing the industry forward. Today, we are a heavy & highway powerhouse, but we started modestly as a pavement & line striping business. It was our hope to one day master all things heavy & highway… and eventually, we did just that! We now specialize in MOT, sign manufacturing, traffic control, and pavement markings. Take advantage of our in-house maintenance of traffic experts and allow us to assist in your next project.
