Iowa DOT News Release

Iowa 146 bridge over the Union Pacific Railroad in Le Grand to remain closed until June 2019

Posted on: December 07, 2018

MARSHALLTOWN, Iowa – Dec. 7, 2018 – Construction work on the Iowa 146 bridge over the Union Pacific Railroad in Le Grand is delayed and Iowa 146 traffic will be detoured around the work zone during the winter months. The Iowa Department of Transportation’s Marshalltown construction office anticipates the roadway will reopen to traffic in June 2019, weather permitting.

Approximately two miles of Iowa 146 has been closed to traffic and detoured since April 2018 when the at-grade crossing with the Union Pacific Railroad was closed. The closure is allowing construction crews to construct a new bridge and approximately two miles of highway.

This construction project was expected to be completed by November 2018. However, the weather and other contributing factors created the delay in the project completion. We appreciate your patience and apologize for any inconvenience this may cause.

The Iowa DOT reminds motorists to drive with caution, obey the posted speed limit and other signs in the work area, and be aware that traffic fines for moving violations are at least double in work zones. As in all work zones, drivers should stay alert, allow ample space between vehicles, and wear seat belts.
