Proposed bridge raising projects on Interstate 29 in Woodbury County

About the Project

No meeting - The Iowa Department of Transportation is requesting public input for proposed bridge raising projects on Interstate 29 in Woodbury County. The project includes raising the height of the:

  • Woodbury County Road D-65/310th Street Bridge (2.2 miles north of Iowa 141) 1-foot 7-inches, and
  • Woodbury County Road K-35/Carroll Avenue Bridge (4.2 miles north of Iowa 141) 1-foot 5-inches.

New bridge approaches will be constructed, guardrails installed, and field fence replaced. When complete, the two bridges would have a clearance height of 16-feet, 6-inches.

Through traffic would be detoured during construction.

  • The detour for D-65/310th Street would be Cass Avenue, 330th Street, Woodbury County Road K-35, and Old Highway 75.
  • For K-35/Carroll Avenue, traffic would be detoured using Carroll Avenue, 280th Street, Old Highway 75, and Poplar Street/Woodbury County Road K-25.
