CADD_FILE_-_Eckert_Road_Bridges_-TBMs_5-18-26.TXT

This is a CADD (Computer-Aided Design and Drafting) file containing survey data and temporary benchmark (TBM) coordinates for the Eckert Road Bridges project in Boise, Idaho. The file lists eight temporary benchmarks with their respective coordinates and descriptions, including horizontal positioning (northing and easting), elevation data, and physical marker identifications such as caps, nails, and utility box references. These benchmarks serve as reference points for the construction and engineering work associated with the Eckert Road Bridges 2147 and 2148 project, which involves demolition of existing bridge structures and construction of new bridges over the Boise River and Ridenbaugh Canal, a single-lane roundabout at the intersection of Eckert Road and Boise Avenue, and reconstruction of roadway approaches.

The survey data provided in this technical file supports the broader project scope that includes multi-use pathway construction, a Greenbelt underpass, Barber Park driveway modifications, and various infrastructure improvements including pavement, drainage, irrigation, utilities, traffic control, signage, illumination, landscaping, and environmental protection measures. All work involving irrigation and bridge construction must be completed in accordance with the NMID (North & Middle Idaho District) Approval Letter dated 07/16/2026, unless otherwise approved by the irrigation district. The benchmark coordinates and elevations documented in this file are critical for ensuring accurate site preparation and construction execution throughout the project.
