14th Street - Warlick Blvd - Old Cheney Road Intersection Improvement Project: Need for Improvement

Latest News

July 29, 2015 - Design Competition Winner is Announced

Mayor Chris Beutler announced today that the winning alternative is the FHU design to provide a long term solution for the 14th Street, Old Cheney and Warlick Blvd. intersection. The city’s study of its roundabouts prove they are safer and provide more efficient traffic movement than many traditional intersection designs.

Lincoln's residential and commercial growth to the south has significantly increased traffic flows in the project area.

  • More development is planned to the south and population and traffic congestion will only increase if improvements are not made.
  • Peak traffic flows in the morning and late afternoon must be addressed.
  • Residents, businesses and commuters traveling through the project area agree that something must be done.

Safety is the most important priority for drivers, pedestrians and bicyclists.

Crash data for 14th/Warlick/Old Cheney area from January 1, 2007 – December 31, 2011:

14th & Old Cheney Intersection
11 - Injury
45 - Property Damage
15 - Non Reportable
Warlick & Old Cheney Intersection
14 - Injury
11 - Property Damage
5 - Non Reportable
14th Merge Lane onto Warlick Blvd
2 - Injury
3 - Property Damage
0 - Non Reportable

Congestion during peak travels times must be addressed.
