COUNCIL BLUFFS, Iowa – Sept. 25, 2018 – As part of the ongoing Union Pacific Railroad bridge replacement project, Interstate 29 road closures will be necessary beginning Sunday, Sept. 30 to complete the demolition of the south half of the existing bridge over I-29 in Council Bluffs, weather permitting, according to the Council Bluffs Interstate Project Office.

Closures will occur as follows:

  • Sept. 30-Oct. 2: Southbound I-29 will close Sunday night, Sept. 30, at 10:30 p.m. through Tuesday, Oct. 2, at 5:30 a.m.
  • Oct. 2-4: Northbound I-29 northbound will close Tuesday night. Oct. 2, at 10:30 p.m. through Thursday, Oct. 4, at 5:30 a.m.

The Union Pacific Railroad bridge is located approximately one-half mile north of the I-80/I-29 interchange. Reconstruction of the Union Pacific Railroad bridge is necessary to allow for increased capacity on I-29. The existing bridge will be rebuilt from its existing five tracks to three tracks to improve local yard operations. The railroad bridge replacement project is scheduled to be completely in 2019.
