The second and final segment of the Highway 100 extension project will be open to traffic on Wednesday, Dec. 12, according to the Iowa Department of Transportation.

The highway will be usable by drivers beginning at around 4 p.m. The final four miles of four-lane road completes a full beltway around the Cedar Rapids metro area, when combined with U.S. Highways 30 and 151 on the south and east sides.

A ribbon cutting for the project was held on Dec. 1, and the first segment of the extension opened in Dec. 2016.
