Celebrate Engineers Week! Each year, Engineers Week (EWeek) brings together engineers, students, and communities nationwide to recognize how engineering shapes the world around us. Founded by the National Society of Professional Engineers in 1951, EWeek is more than a celebration, it’s a call to inspire the next generation. In 2026, EWeek takes place February 22–28. This year’s theme, “Transform Your Future,” highlights the power of engineering to create opportunity, drive innovation, and build stronger communities. From the roads we travel to the bridges that connect us, engineering truly transforms our future. #EWeek2026

Engineering innovation was on full display at the 6th Annual Central Ohio Miniature Bridge Building Competition! We were proud to once again host this hands-on STEM experience alongside the Central Ohio Association of Bridge Construction and Design, Ohio Department of Transportation - Columbus District 6, The Ohio State University College of Engineering, the American Society of Civil Engineers, OSU Student Chapter, and the American Institute of Steel Construction.

This year, 347 students from 17 schools across five counties formed 142 teams and put their bridges to the test, competing for the highest load-to-weight ratio. The excitement in the room was undeniable as every bridge faced the ultimate challenge. We’re proud to keep building opportunities that connect students to real-world engineering and to help shape the next generation of problem-solvers right here in Central Ohio.
