CADD_FILE_-_Eckert_Road_Bridges_-_WORKMAP-20260211_linework.dwg

This is a Computer-Aided Design (CAD) file related to the Eckert Road Bridges project in Boise, Idaho, specifically depicting linework for two bridge structures (Bridges 2147 and 2148) spanning the Boise River and Ridenbaugh Canal. The file serves as technical documentation supporting the state and local contract opportunity for this comprehensive infrastructure project. The project encompasses demolition of existing bridge structures, construction of new bridges, development of a single-lane roundabout at the intersection of Eckert Road and Boise Avenue, and reconstruction of roadway approaches. Additional project components include a multi-use pathway along the west side of Eckert Road, a Greenbelt underpass beneath Eckert Road, and modifications to the Barber Park driveway access. The scope further incorporates 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 be completed in accordance with the NMID Approval Letter dated July 16, 2026, unless otherwise approved by the irrigation district. The CAD file represents the technical planning and design phase necessary to guide the subsequent bidding and construction processes. This file is essential for contractors to understand the precise specifications and layout requirements for the project, ensuring compliance with engineering standards and project specifications outlined in the contract opportunity.
