Specifications include, but are not limited to: The project includes Schram Road Improvements from Copper Ridge Road to 234th Street (roughly 8,000 linear feet) in Gretna, Nebraska. The project is expected to consist of removal of the existing gravel road surfacing and replacement with new drive lanes. Portions of adjoining roads and private driveways are expected to require removal and replacement as well. The new roadway will generally align with the existing Schram Road, but some widening of the footprint and a straighter alignment is expected. The new roadway surfacing is anticipated to be Portland cement concrete (PCC) construction. Some of the existing culvert structures (CMP and RCP) are expected to be removed and replaced as part of the project. Significant grading is expected in some areas. Up to about 10 feet of new fill is expected within the proposed roadway and up to about 15.5 feet of new fill is expected outside of the proposed roadway but within proposed culvert locations. Soil retaining walls may become necessary along the proposed roadway and/or culverts to support differential grades if sufficient right-of-way cannot be obtained. Based on the preliminary project plans, necessity, materials and construction methods of any retaining walls are currently not expected. Should such structures become necessary, additional geotechnical recommendations relating to wall systems can be provided.
