CADD_FILE_-_Eckert_Road_Bridges_-24006-Topo-(EG).dwg

This is a CADD file (AutoCAD drawing file) related to the Eckert Road Bridges project in Boise, Idaho, prepared for the City of Boise. The file contains topographical information and design drawings for the construction of two new bridges (Bridges 2147 and 2148) spanning the Boise River and Ridenbaugh Canal at the intersection of Eckert Road and Boise Avenue. The project encompasses demolition of existing bridge structures, construction of a single-lane roundabout at the Eckert Road and Boise Avenue intersection, and reconstruction of roadway approaches. Additional components include a multi-use pathway along the west side of Eckert Road connecting the Boise River Greenbelt to Boise Avenue, a Greenbelt underpass beneath Eckert Road linking to the Dallas Harris Legacy Walkway, and modifications to the Barber Park driveway access.

The CADD file serves as a technical design document supporting the project scope, which includes roadway excavation and embankment, pavement construction, curb and gutter installation, sidewalks, retaining walls, drainage improvements, irrigation and utility adjustments, traffic control, permanent signing and markings, illumination, landscaping, and erosion and sediment control measures. All irrigation and bridge work must comply with the NMID (North and Middle Idaho Irrigation District) Approval Letter dated July 16, 2026, unless otherwise approved by the irrigation district. This technical drawing file is essential for contractors and bidders to understand the precise design specifications and site conditions necessary for accurate project estimation and execution.
