The crews that repaired Interstate 85 did so in about six weeks. But it wasn't all high tech equipment that was used.

Sometimes a kid’s toy is what you need.

The Georgia Department of Transportation reached an agreement with Legoland Discovery Center, at Phipps Plaza, to build bridges. And so more than 1,500 children started working.

"And we agreed with them to talk about bridge building," says GDOT Commissioner Russell McMurray. "They launched a project to build their own bridge."

McMurray spoke about the agreement with Lego at a ribbon cutting for the new I-85. He was joined by Governor Nathan Deal, U.S. Transportation Secretary Elaine Chao, state and local officials, first responders, and a model of the new interstate bridge, made of Legos.

"Over 15,000 Legos (were used), as well,” says McMurray. "So we're going to be out later at Legoland, recruiting for future engineers.”

The crews that repaired the interstate finished their work about month before the target date of June 15. The bridge collapsed, due to fire, on March 30.
