Model of Four Corners Intersection

Community Report

Treynor (population 950) is located along Highway 92 within commuting distance of Omaha and Council Bluffs. Many residents work in the cities, but love raising their families in Treynor’s small-town atmosphere. Traffic flow through town is problematic because Highway 92 is the only east-west road through town and Eyeberg Street is the only through north-south road.

Community Assessments

Focus-group participants revealed that residents take pride in East Park with its updated lighting and shaded play place. Although an important throughway in town, Highway 92 is perceived as a barrier because of heavy traffic. Congestion at school dropoff and pickup times exacerbates the problem. The lack of continuous sidewalks, heavy traffic on Highway 92, and few crosswalks create difficulty walking and biking throughout town.

Residents desire a safe and accessible trail and sidewalk system!

Planning and Design Summary

Based on the assessments and the Treynor visioning committee’s identified goals, the design team proposed the following projects:

  • Highway 92 Reconfiguration — Implement bump-outs and extend the curb along the wide shoulders currently utilized for on-street parking to reduce the perception of the roadway from a wide open four-lane highway to a slower two-lane community scale street.
  • “The Four Corners” — Incorporate pedestrian-scale streetlights, banners, and landscape updates to establish an identity for the downtown district.
  • Green Infrastructure — Incorporate bioswales, rain gardens, and permeable pavement into the streetscape. Where current stormwater inlets exist, add bump-outs formed to direct stormwater from the roadway to the existing drain.
  • Sidewalk Updates — Replace and install sidewalks in three phases, starting with locations identified by residents; and add crosswalks along Highway 92.
