Thanks to Dennis Byers at Omaha Parks for letting us know about this trail closure.
Keystone Trail Closure – Dodge Street South to the NFM Pedestrian Bridge
A section of the Keystone Trail from Dodge Street south to the Nebraska Furniture Mart Pedestrian Bridge will close for 2 months starting on Tuesday, December 26, 2017 for the demolition of NFM warehouse buildings that abutt the trail. Trail will reopen on Wednesday, February 21, 2018. A suggested detour is to use Dodge Street and Rose Blumkin Drive.
For a detour, trail users can use Dodge Street and Rose Blumkin Drive. I’ve attached a map that shows the closed section as well as a suggested detour.
