Proposed Construction: The existing 2-lane highway will be rebuilt and widened to a 4-lane divided highway on new alignment. Beginning in Gretna the additional lanes are added along the north side of the existing highway, before crossing over to the south side of the existing highway near 192nd Street and continues along the south side of the existing highway to the I-80 interchange.
Highway improvements also include reducing the grade of the highway, better sight distance, building flatter side slopes, improving roadway drainage, rebuilding the bridge at Wehrspan Lake, adding a continuous raised median with left-turn lanes and adding surfaced shoulders. In Gretna, a small segment of the existing roadways leading to and including the intersection of US-6 / N-31 / N-370 / Gruenther Road will be partially rebuilt to add additional lanes, improve turning radii and adding sidewalks at selected locations.
Updating of overhead lighting and updating traffic
signals will occur at selected locations.
Right of Way: Acquisition of property for highway right-of-way will be required throughout the length of the project. The new right-of-way limits will accommodate future expansion of Nebraska 370 to six lanes. Control of access to the new highway will be acquired.
Phasing: Construction will be done under traffic. Temporary roads around work zones will be used during some phases of construction. Two construction seasons will be required to build the project.
Schedule: The project is currently programmed to be let to contract in December of 2008, with construction beginning in April of 2009 and ending in 2010. Please note this schedule is assuming funds will be available.
Estimated Cost: Approximately $15,000,000 (present day dollars)
