As many as 15,000 vehicles per day are expected on the new 1.3-mile segment of Highway 100 in northeast Cedar Rapids which opens at 11 am Wednesday. The $3.2 million highway is an extension of Collins Road NE, connecting Interstate 380 and Edgewood Read NE. The opening also will complete the tri-level interchange of I-380.

The IA 100 freeway between Covington Road and US 30 will open this afternoon in time for rush hour, the DOT says. This will include an exit at E Avenue along with new ramps to/from US 30/218 and a repurposing of the exit ramp to from 30 to 16th Avenue.
This will complete a project that’s been on wish lists for decades. Its physical existence started with construction of I-380 and the volleyball interchange at Collins Road (with Blairs Ferry Road and 42nd Street partially thrown in) and the removal of IA 150 through Cedar Rapids. IA 100 was created in August 1984, with an extension to Edgewood Road in 1985 serving as an unfinished interchange for more than 30 years. An eastward extension to IA 13 is not a full expressway, but serves as a bypass of Marion.
