Northbound Interstate 29 on- and off-ramps at the U.S. 275/ Iowa 92 Interchange (Exit 47) are expected to remain closed for approximately one year. It is expected that additional lane closures will occur throughout the construction season.

Traffic has been reduced to one lane in each direction on U.S. 275/Iowa 92 since June 2014 to allow for reconstruction of the new westbound bridges and adjoining pavement. In mid-August 2015, U.S. 275/Iowa 92 traffic will move from the eastbound lanes to the newly-finished westbound lanes.

I-29 may have one or two overnight closures near the interchange to remove the existing U.S. 275/Iowa 92 eastbound bridge after the traffic shifts to westbound lanes. Detours will be posted and drivers will be notified in advance.

Iowa DOT is in the process of reconstructing I-80, I-29 and I-480 in the Council Bluffs metropolitan area. The DOT says this comprehensive interstate redesign will modernize the highway system and improve mobility and safety of approximately 18 miles of interstate. Motorists are encouraged to allow for extra travel time while this interstate improvement takes effect.
