I-74 bridge arches require engineering precision

4 The Record

Major installation will close channel to barge traffic

Interstate 74 project manager Danielle Alvarez joined 4 The Record this week. This is the second part of that conversation.

They’re a spectacular feature. Not easy to build.

Alvarez walked us through how complicated it is, the next big milestone and how confident she is that the Iowa-bound bridge will be open next year.

Watch the full conversation in the video above.
