CADD_FILE_-_Eckert_Road_Bridges_-TBMs_5-18-26.CSV

This is a CADD file containing surveying data for the Eckert Road Bridges project in Idaho, specifically documenting temporary benchmark (TBM) coordinates and elevations for bridges 2147 and 2148 spanning the Boise River and Ridenbaugh Canal. The file includes eight surveyed points with their northing and easting coordinates in State Plane coordinates, corresponding elevations in feet, and feature codes identifying benchmark types such as concrete box markers with witness posts and nailed reference points. These survey monuments establish the vertical and horizontal control necessary for the design and construction of the new bridge structures, roadway approaches, and associated infrastructure improvements at the intersection of Eckert Road and Boise Avenue in Boise, Idaho.

The benchmark data serves as the foundational surveying information for a comprehensive infrastructure project that includes demolition of existing bridges, construction of new spans, installation of a single-lane roundabout, multi-use pathway development, greenbelt underpass construction, and various roadway improvements including drainage, utilities, landscaping, and erosion control. All work involving irrigation and bridge construction must comply with the NMID Approval Letter dated July 16, 2026, ensuring coordination with the local irrigation district and adherence to applicable regulations and specifications for the project completion.
