I-29 Improvement Project

Segment 2: Downtown corridor

The Segment 2 study area is the downtown portion of I-29 in Sioux City. The project area begins approximately one-quarter mile south of the Burlington Northern Santa Fe (BNSF) railroad bridge over the Missouri River and ends west of the Hamilton Boulevard interchange. The project area encompasses the existing Floyd Boulevard, Pierce Street, Nebraska Street, U.S. 77/Wesley Parkway and Hamilton Boulevard interchanges, as well as several local street connections.

Proposed improvements to Segment 2 are more extensive than the other segments and will include upgrading mainline I-29 from four lanes to six lanes, as well as upgrading several of the interchanges within the study area.

An environmental impact statement (EIS) study and record of decision (ROD) have been signed and completed. Timing of improvements within this segment will be dependent on funding availability and staging of improvements among the other segments of I-29.
