Interstate Changes Happening in Council Bluffs next week

COUNCIL BLUFFS, Iowa – May 11, 2023 – Motorists should be prepared for changes to Interstate 80, I-29, and Northbound Frontage Road in Council Bluffs next week that may slow down their trip.

On Sunday night, May 14, weather permitting, the ramp from future northbound I-29 and Northbound Frontage Road to westbound I-480 is scheduled to open at around 11 p.m. This change will allow detoured interstate traffic traveling towards westbound I-480 to merge onto the interstate sooner, instead of driving to West Broadway. The ramp can be accessed from the left lane on Northbound Frontage Road. When northbound I-29 opens, the ramp will be accessible from the right lane, which is different from the previous interchange configuration.

Furthermore, the ramp from Madison Avenue to eastbound I-80 is anticipated to close early Monday, May 15, around midnight. This closure may last up to six months. The closure will allow construction crews to rebuild the ramp and connect it to the new eastbound bridge that is currently being built. Motorists should follow the marked detours during this time.
