CADD_FILE_-_Eckert-BoiseAve_Roundabout_-_B&N_combined_basemap.dwg

This is a CADD (Computer-Aided Design and Drafting) file containing the combined basemap for the Eckert Road Bridges and Boise Avenue Roundabout project in Idaho. The file provides the technical design documentation for a comprehensive infrastructure project involving the Idaho jurisdiction. The project scope includes demolition of existing bridge structures (Bridges 2147 and 2148) spanning the Boise River and Ridenbaugh Canal, construction of replacement bridges, installation of a single-lane roundabout at the Eckert Road and Boise Avenue intersection, and reconstruction of roadway approaches. Additional project components encompass a multi-use pathway along the west side of Eckert Road, a Greenbelt underpass beneath Eckert Road, modifications to Barber Park driveway access, roadway excavation and embankment work, pavement construction, curb and gutter installation, sidewalks, retaining walls, drainage improvements, irrigation and utility adjustments, traffic control measures, permanent signing and pavement markings, illumination, landscaping, erosion and sediment control, and environmental protection measures.

All work involving irrigation and bridge construction must comply with the NMID (Nampa-Meridian Irrigation District) Approval Letter dated July 16, 2026, unless otherwise approved by the irrigation district. The CADD basemap serves as the foundational design reference for contractors bidding on this project, providing the necessary technical specifications and site layout information required for project planning, estimation, and execution.
