POV: You’re driving by wondering what we’re building. 👀

Here’s a look at the foundation work for the future Roanoke Lid — yes, the park that’ll sit over this stretch one day. Every glow-up has an awkward stage, right? Trust the process. 🙏

Just an engineer… standing just east of the world’s longest floating bridge… in the rain… asking you to believe in buoyancy...

By the way: Halloween night remains one of the most dangerous nights of the year for pedestrian safety. Keep your eyes peeled and stay alert tonight! Don’t wait on Batman. 🦇

That time of year when the SR 520 Trail looks like a Bob Ross painting. 🧑‍🎨

Some clouds and morning drizzle. A sunbreak here and there. And, of course, a palette of happy little trees and thriving restored wetlands. 🌳🍂

Do you have a Good To Go! account but no pass?
Then you’re missing out on some savings!
A pass is the only way to pay the lowest toll rate. If you don’t have one, you’re paying 25 cents more for every trip you take.
