Intern Summer 2026: Complete! 🎓

Last week, our six interns wrapped up their final projects at CBB, and we celebrated with a farewell lunch and a Cardinals outing. ⚾ Throughout the summer, they got a behind-the-scenes look at what it takes to keep a transportation engineering and planning firm moving, from field visits and professional organization lunches to golf tournaments, project work, and learning the inner workings of CBB. More importantly, they brought new perspectives, curiosity, and lots of energy to the team.

We're proud of everything they accomplished this summer and grateful for the time we got to spend with them. Congratulations, interns, and best of luck on what's next! 👏

🚦Our summer interns recently toured the Missouri Department of Transportation's Traffic Management Center (TMC), part of MoDOT's Gateway Guide program, getting a firsthand look at how traffic is monitored and managed across the region.
