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

This is a CADD (Computer-Aided Design and Drafting) file related to the Eckert Road Bridges project in Boise, Idaho, specifically depicting the bridge surface topography for Bridge Structures 2147 and 2148. The file supports a major infrastructure project involving the City of Boise that encompasses demolition of existing bridge structures and construction of new bridges spanning the Boise River and Ridenbaugh Canal at the intersection of Eckert Road and Boise Avenue. The scope of work includes construction of a single-lane roundabout, reconstruction of roadway approaches, a multi-use pathway along the west side of Eckert Road connecting to the Boise River Greenbelt, a Greenbelt underpass beneath Eckert Road, and modifications to the Barber Park driveway access. Additional project components include 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 markings, illumination, landscaping, erosion and sediment control measures, and environmental protections.

All irrigation and bridge work must be completed in accordance with the NMID (North Mores Irrigation District) Approval Letter dated July 16, 2026, as referenced in the project attachments, unless otherwise authorized by the irrigation district. The CADD file provides essential design documentation for bidders to understand the precise topographical and structural specifications of the bridge surfaces, enabling accurate cost estimation and construction planning. This technical drawing is a critical component of the contract documentation package and supports the bidding process for this significant infrastructure improvement project.
