AUSTIN (KXAN) — Thanks to the Texas Department of Transportation and the Make-A-Wish Foundation, a six-year-old Leukemia survivor got to push the button to bring down part of the U.S. Highway 183 and Interstate 35 flyover Saturday morning.

The child, named Archer, helped TxDOT crews implode a portion of the flyover so they can rebuild it to make it longer and not as steep. It’s the last portion of the flyover to be demolished — and Archer had the honor of bringing it all down.

“I blew up a bridge,” said Archer on Saturday morning. “It was fun and it was loud!”

Crews have been working to implode the stretch of road for the past couple of weeks, and once the remainder of the flyover is brought down Saturday, the rebuilding can begin.

The boom happened at 6 a.m. Saturday morning and all lanes of I-35 and U.S. 183 interchange were closed for two hours to accommodate.

Work to rebuild the flyover is expected to take four months, and once it’s done, there will be new northbound bypass at St. John’s Avenue and a new on-ramp to northbound I-35. During the work, those on northbound I-35 who need to get on U.S. 183 northbound will have to use the Rundberg Lane exit and then U-turn to use a new flyover.
