Highways are the lifelines of our daily commutes, weekend getaways, and cross-country adventures. But behind the scenes, there’s always a lot happening to keep them safe and efficient—and that’s where road construction and professional flagging step in.
Here are some fun (and surprising!) facts about highways—and how they connect to the work Summit Flagging does every day.
Did You Know?
- At any given time, nearly 20% of U.S. highways are under construction.
That means one out of every five trips you take could pass through a work zone. Flaggers and traffic control crews play a critical role in keeping traffic flowing while keeping workers safe. - The U.S. has over 4 million miles of roads.
Imagine how many cones, barricades, and flaggers are needed to manage work zones across that massive network. Summit Flagging makes sure Pennsylvania’s share is handled with professionalism and precision. - Highways are built to last—but they require ongoing maintenance.
The average interstate is designed for about 50 years of use, but with millions of vehicles traveling daily, maintenance and upgrades are essential. That’s why flagging is such a big part of construction—keeping drivers, crews, and communities safe while improvements are underway. - The longest straight stretch of highway in the U.S. runs 30 miles.
Even on the “boring” stretches, safety comes first when construction zones appear. Summit’s trained flaggers and AFADs (Automated Flagger Assistance Devices) ensure traffic is managed safely—no matter how straight or winding the road.
Why Summit Flagging Matters in Work Zones
Work zones aren’t just about cones and signs—they’re living, moving spaces where vehicles and crews interact. Summit Flagging helps bridge that gap by:
- Keeping Projects On Time with our On-Time Guarantee
- Protecting Crews & Drivers with trained, certified flaggers and best-in-class safety protocols
- Managing Traffic Flow so even during detours, delays are minimized and drivers stay safe
Whether it’s a small municipal project or a major highway reconstruction, Summit Flagging is the force behind the flow.
The Takeaway
Next time you’re driving and see a work zone, remember:
- Highways are constantly evolving.
- Flaggers are the frontline of safety.
- Summit Flagging is here to keep Pennsylvania’s roadways moving—one safe, smooth project at a time.
