The interchange of I-35W and I-494 is one of the worst in the nation when it comes to congestion. According to the Federal Highway Administration, it's the 17th worst in the nation.

On Tuesday, two of the top-ranking officials in the state - Lt. Gov. Tina Smith and state transportation commissioner Charlie Zelle - will share Gov. Mark Dayton's plan for fixing that.

Smith and Zelle will be joined by local business leaders and mayors on the American Boulevard overpass at 8 a.m. where they will outline the governor's proposal to rid the Twin Cities of the bottlenecks that develop almost daily.

About 290,000 vehicles pass through the interchange on the border of Richfield and Bloomington each day, or one-fifth of the total traffic in the Twin Cities, according to the Minnesota Department of Transportation.
