The Iowa Department of Transportation reports that on the evening of Tuesday, August 14th, weather permitting, Iowa DOT maintenance crews will be changing exit number signing on Interstate 29 for the 24th Street and South Expressway exits in Council Bluffs (see map). The change is designated to follow I-29 mileage for the final design of the dual-divided freeway. The outside lanes of the dual-divided freeway will be designated I-29/I-80 local and will follow the I-29 mileage in the ultimate design of the system.
Iowa DOT is in the process of reconstructing I-80, I-29 and I-480 in the Council Bluffs metropolitan area as part of the Council Bluffs Interstate Improvement Program. This comprehensive interstate redesign, which will be delivered over the next eight-to-10 years, will modernize the highway system and improve mobility and safety of approximately 18 miles of interstate.
