E&A’s design will turn US-30, a two-lane rural highway, into a 4-lane expressway. We reviewed and calculated environmental impacts on several alignments to assist the Nebraska Department of Transportation in choosing the final alignment which follows existing US-30 for 2 miles before heading off on a new alignment. Our design includes a bypass to the north of North Bend.
E&A is responsible for the design of this 20.5 mile project in its entirety; from preliminary through final designs, as well as a hydraulic & hydrologic (H&H) ice affected study, hydraulic surveys to support the study, and a final report. We also provided design support for environmental documentation and permitting and assisted with public meetings.
Our designers were able to create a model using MicroStation/GEOPAK OpenRoads and produce final plans to meet a very aggressive project schedule. E&A staff also worked with NDOT on preparing a Conditional Letter of Map Revision (CLOMR) which has been reviewed and approved by FEMA.
