Columbus South Mobility Study


The City of Columbus conducted the Columbus South Mobility Study to evaluate the potential need for improvements to safely and efficiently move east-west vehicle and pedestrian traffic in the southern portion of the City. This study was a recommended action item from the Long Range Transportation Plan developed in 2018 and was included in the budget as authorized by the City Council. The study area primarily focused on 8th Street from U.S. Highway 30/81 (33rd Avenue) on the west to just past 3rd Avenue on the east. The northern limits of the study area extended to the Union Pacific Railroad (UPRR) tracks and the southern limits of the study area extended to the Loup River Levee. View the study area (PDF).


The Columbus South Mobility Study was conducted in 2020 and began with data collection and a traffic and safety analysis. This analysis included a review of crash and congestion data, historical and current traffic volume data, and future traffic forecasts within the study area. Following data collection, alternatives were developed to help facilitate safe and efficient traffic movements. Alternatives were evaluated and took a variety of criteria into consideration, including:

  • Safety
  • Impacts to vehicle travel, including travel efficiency, connectivity and speeds
  • Impacts to pedestrians and bicycle traffic
  • Impacts to neighborhoods
  • Construction impacts, including access, right-of-way, environmental and utility impacts
  • Feasibility, including ease of implementation and potential costs
  • Public feedback

The alternatives evaluation culminated into the City selecting a recommended alternative, identified in the final study report (PDF). This study is a preliminary look at implementing any changes in the study area. Further analyses and design would need to be conducted prior to any construction.

Past Public Involvement

In February and March 2020, the City asked interested individuals to take a short survey about their experience traveling through the study area. View the survey results.

In the June 2020 alternatives evaluation phase, the City hosted an online meeting that provided the public the opportunity to review and comment on draft alternatives.
