CADD_FILE_-_Eckert-BoiseAve_Roundabout_-_24006-Topo-(Bridge_Surface).dwg

This is a Computer-Aided Design (CADD) file related to a bridge and roundabout construction project in Idaho. The file, identified as "CADD_FILE_-Eckert-BoiseAve_Roundabout-_24006-Topo-(Bridge_Surface).dwg," contains technical design drawings for the topographical and bridge surface components of the Eckert Road Bridges project at the intersection of Eckert Road and Boise Avenue. The project involves the demolition of existing bridge structures (Bridges 2147 and 2148) that span the Boise River and Ridenbaugh Canal, followed by construction of new bridges and a single-lane roundabout at the Eckert Road and Boise Avenue intersection, along with reconstruction of roadway approaches.

The project scope extends beyond bridge and roundabout construction to include a multi-use pathway along the west side of Eckert Road between the Boise River Greenbelt and Boise Avenue, a Greenbelt underpass beneath Eckert Road, modifications to the 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, 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 Approval Letter dated July 16, 2026, unless otherwise approved by the irrigation district. This CADD file serves as a critical design document providing the topographical and bridge surface specifications necessary for bidders and contractors to understand the technical requirements and execute the project in accordance with the approved plans and specifications.
