We've gotten a fair amount of Why Guy questions about bridges and roads. Many of you are fascinated by infrastructure, and how our taxes are hiked to pay for it all.

Speaking of roads, California has 395,000 miles of them, with only Texas having more. But it’s a three-quarters-of-a-mile stretch along Interstate 5 in Sacramento that's the focus of this Why Guy.

That didn't happen. But the project did get a nickname!

"They called it the boat section because in the old days, that area used to flood and the only way to pass through it was in a boat," Dennis Keaton, Public Information Officer for Caltrans, said.

The boat section of I-5 was built below the water level of the Sacramento River and had a long history of being a flooded stretch of highway. Not anymore.
