Officials say a repair and repaving project will force closure of a portion of U-S Highway 75 in southeast Nebraska.  The Nebraska Roads Department says a 12 mile stretch between Union and NebraskaCity will be closed beginning march 31st.  The Highway is expected to remain closed until mid-September.  Access for local residents will be maintained on county roads.

The project will include bridge repairs, grading, drain work and repaving.
