This letter report details the findings of a pre-rehabilitation asbestos survey conducted by Northern Industrial Hygiene, Inc. on April 25, 2023, at the Milwaukee/Calypso Bridge near Terry, Montana. Performed on behalf of Robert Peccia and Associates, the inspection identified potential hazardous materials prior to planned bridge resurfacing and rehabilitation activities. The survey involved collecting bulk samples of suspect materials, which were analyzed via Polarized Light Microscopy (PLM) at EMSL Analytical, Inc. Of the four suspect materials tested—concrete, paint coatings, under-bridge tar, and bridge deck tar—one material was confirmed to contain asbestos. The "Black Tar on Wood Bridge Deck" (Material M20.1) was found to contain 5% Chrysotile asbestos, classifying it as a NESHAP Category II non-friable asbestos-containing material (ACM). To ensure safety and regulatory compliance, Northern Industrial Hygiene recommends retaining an accredited asbestos abatement contractor to remove the ACM before any demolition or renovation work impacts the material. Additionally, they advise hiring an independent third party to conduct final visual clearance testing post-abatement. The bridge owner or operator must maintain a copy of this report on-site during the project and make it available to the Montana Department of Environmental Quality (MDEQ) upon request.

The Western Federal Lands Highway Division (WFLHD), in partnership with Prairie County, Montana, is delivering the design and construction of the Milwaukee Bridge resurfacing and rehabilitation project over the Yellowstone River. The existing bridge was classified as scour-critical, with a 2015 inspection showing undermining at the upstream face of Pier 4. To mitigate these safety concerns, WFLHD conducted a detailed hydraulic and hydrologic analysis. Peak discharges were computed using the USGS StreamStats program, and a two-dimensional, steady-state hydraulic analysis was performed using SRH-2D modeling software. The scour analysis, completed under HEC-18 guidelines, estimated a contraction scour depth of approximately 3 feet for a 500-year flow event, alongside an assumed long-term bed degradation of 2 feet. While an Articulated Concrete Block (ACB) system was initially considered for pier scour protection, feedback from the regional U.S. Fish and Wildlife Service and the Montana Department of Transportation regarding the historical ineffectiveness of ACBs in the state led to a design change. WFLHD recommends installing Class 5 riprap around Pier 4 to mitigate scour risks. The final design specifies placing a 5-foot-thick layer of Class 5 riprap extending 32 feet in all directions around the pier, with the top set at the channel bed. The riprap toe will be placed 34 inches below the channel bottom for the first 5 feet, extending to a depth of 5 feet for the remaining length, and underlain by a geotextile filter layer.

Key technical data illustrated on each cross-section includes: - Design grades (Des Grade) and original ground elevations (Original Grnd), with elevations generally averaging between 2,227 and 2,230 feet. - Cross-slope percentages (e.g., -3.0%, -4.0%, -6.0%) and cut/fill slope ratios (ranging from 1:1.5 to 1:8.6). - Precise right-of-way (R/W) boundaries and horizontal offsets. - Locations of underground utility features, specifically identifying fiber optic lines running parallel to the roadway between stations 116+50.00 and 118+00.00. These technical cross-sections serve as standard civil engineering reference plans, crucial for bidding contractors to estimate earthwork volumes, grading requirements, and utility coordination for the rehabilitation project.

This XML document represents a LandXML data file (version 1.2) containing geographic and geospatial civil engineering data for a public works project. Generated on February 12, 2026, using Bentley Systems' OpenRoads Designer application, the file details the "MT PRAIRIE 2016(3)" project, which focuses on the "Milwaukee Bridge Resurfacing and Rehabilitation" initiative. The dataset establishes imperial measurement standards for the project, including square feet for area, feet for linear distance, and cubic yards for volume. The core of the document defines a 3D Triangulated Irregular Network (TIN) surface named "TERR_PRO_ALI_MAIN_01a." This surface definition contains a detailed list of precise coordinate points (easting, northing, and elevation) that map out the physical terrain of the bridge rehabilitation site. This technical survey and design file is a standard component of state and local construction RFPs, providing bidding contractors with the exact digital terrain models necessary to estimate earthwork volumes, plan grading, and execute the resurfacing and structural rehabilitation of the Milwaukee Bridge.

This LandXML data file is a civil engineering and surveying document supporting the "MT PRAIRIE 2016(3)" project, which focuses on the Milwaukee Bridge Resurfacing and Rehabilitation. Generated using Bentley Systems' OpenRoads Designer (version 10.12.02.4), the file establishes imperial measurement units (feet, square feet, cubic yards) and defines a key digital terrain surface named "TERR_PRO_ALI_MAIN_01b." The core of the document consists of a highly detailed Triangulated Irregular Network (TIN) surface definition. It lists precise three-dimensional geospatial coordinates (Eastings, Northings, and Elevations) for hundreds of survey points across the project area. These data points map the existing topography and structural elevations of the bridge and its surrounding terrain, providing the essential baseline engineering measurements required for the design, bidding, and execution phases of the rehabilitation contract.
