Traffic Impacts

Iowa 14 will remain open to traffic during the bridge overlays on White Breast Creek and Teter Creek.  

Starting spring 2026 through fall, traffic impacts will include staged lane closures on both bridges while the project is underway reducing the crossing to one lane with temporary traffic signals.

Project Overview

White Breast Creek Bridge

White Breast Creek Bridge

The bridge over White Breast Creek was constructed in 1965. Previous work on the structure includes beam repair (1981), overlay and rail retrofit (1989), retrofit of rail ends (2001), and epoxy injection of the bridge deck (2014).  The existing overlay is at the end of its lifespan and there is deterioration of the bridge deck.

To address this we will make the following improvements:

  • Bridge deck overlay.
  • Reconstruct abutment backwalls, barrier rail, and end sections.
  • Reconstruct end of deck and abutment diaphragm.
  • Replace joints at both abutments.
  • Clean and paint girder bearings at the abutments.
  • Reconstruct the top floor beam pedestals at both abutments.
  • Replace approach pavement at both bridge ends.
Teter Creek Bridge

Teter Creek Bridge

The bridge over Teter Creek was constructed in 1965. Previous work on the structure includes beam repair (1981), overlay and rail retrofit (1989), retrofit of rail ends (2001), and epoxy injection of the bridge deck (2014 and 2017).  The existing overlay is at the end of its lifespan and there is deterioration of the bridge deck.

To address this we will make the following improvements:

  • Bridge deck overlay.
  • Reconstruct abutment backwalls, barrier rail, and end sections.
  • Replace joints at both abutments.
  • Clean and paint girder bearings at the abutments.
  • Patch approach pavement at both bridge ends.
