Lyon County weighs options after three bridges on Ibex Avenue fail inspections
Summary
Supervisors were told two bridges on Ibex Avenue south of 210th Street were closed following inspection; the county is studying options including re‑channeling Emery Creek (≈$500,000, up to 80% federal funds) or rebuilding three bridges (≈$350,000). An informational meeting for affected residents was scheduled; consultant and agency approvals will be required.
Two bridges on Ibex Avenue south of 210th Street were closed after a structural inspection, and county supervisors told residents and staff they expect a nearby third bridge to be closed soon, creating persistent access and safety concerns.
Supervisor Kyle Peters briefed the Lyon County Board of Supervisors on inspection findings from Calhoun‑Burns & Associates. The county has two primary options: re‑channel Emery Creek at an estimated cost of about $500,000 with a hopeful ~80 percent federal funding participation, or replace the three structures with steel substructures and timber superstructures at an estimated combined cost near $350,000. The board asked the county engineer’s office to gather detailed cost estimates and to plan an informational meeting for residents in the affected area.
County Engineer Laura Sievers told supervisors that federal or state permits and land purchases may be required if the county elects the creek‑rechanneling option; the U.S. Army Corps of Engineers and the Iowa DNR participate in permitting decisions that can add months to the schedule. Sievers said the county would document options and return with consolidated cost, funding and permitting timelines for board review.
At several later meetings the board set an informational session (May 20) and said it would keep landowners advised as plan details are finalized. The board also discussed whether condemnation would be necessary if property acquisitions cannot be negotiated; supervisors said they would prefer negotiated purchases but might consider condemnation only after exhausted attempts to obtain rights voluntarily.
What happens next: The engineer’s office will produce a comparison of options (rechanneling vs. bridge replacements), including permitting steps, estimated construction timelines and expected local cost shares. Residents will be notified of the informational meeting and the board will publish updates once agency approvals are available.
Provenance: Topic introduced SEG 015–SEG 016; later informational meeting planning SEG 213, SEG 316.
