On February 18 and 19 from 10am to 3pm, celebrate National Engineers Week with our annual Engineering Fest. In 2017, we will explore Chicago’s iconic movable bridges with FREE activities for ages 5–12. Join over 1,500 visitors for a weekend full of family-friendly engineering explorations. Chicago is known for its iconic, moveable bridges that span the Chicago River. Learn from an expert about six different types of bridges, then build your own! At Engineering Fest, the whole family can test out engineering solutions with mixed-media materials.
