This Finding ofNo Significant Impact (FONSI) is MDT FHWA based on the January 2008 EA. After independent evaluation of the EA, and conclude that the EA adequately and accurately discusses the needs, environmental issues and environmental impacts of the proposed project and appropriate mitigation measures. The EA provides sufficient evidence and analysis for determining that an Environmental Impact MDT FHWA Statement (EIS) is not required. and take full responsibility forthe accuracy, scope, and content ofthe January 2008 EA. For purposes of compliance with the Montana Environmental Policy Act (MEPA) (ARM 17.4.609(3)0) and ARM 18.2.239(3XJ)), this FONSI and conclusion that an EIS is not required should be considered part ofthe EA.

TOC ii Montana DepartmentofTransportation Yellowstone River - NE of Livingston November 2008 BR 11-1(44)56 CN 4790 Finding ofNo SignificantImpact 1.0 Introduction This document summarizes the final coordination activities undertaken by the Montana Department of Transportation (MDT) to complete the Yellowstone River - NE of Livingston Environmental Assessment (EA) and Nationwide Programmatic Section 4(f) Evaluation. The EA, which is attached as Appendix D, describes the potential environmental effects of replacing a bridge over the Yellowstone River and its roadway approaches in south central Montana in Park County on State Primary Route 11/US 89 (US 89) at mile post (MP) 55.94. This document affords MDT the opportunity to: present the Finding of No Significant Impact (FONSI) for this project; Identify the alternative that has been selected for this project; summarize the impacts of the selected alternative and the proposed mitigation; summarize the efforts undertaken to coordinate with the public and agencies; summarize the primary issues and concerns expressed by the public and agencies; modify the text of the EA distributed on January 30, 2008; and respond to written and verbal comments submitted at the February 2008 Public Hearing and during the comment period (January 30, 2008 to March 3, 2008). 2.0 Selection of Preferred Alternative Based on the Yellowstone River - NE of Livingston EA (Appendix D) and the public and agency comments and responses (Chapter 6), MDT and the Federal Highway Administration (FHWA) have selected the Preferred Alternative. The Preferred Alternative is Alternative 1, which is described in Chapter 2 of the attached EA. Proposed improvements include replacing the existing bridge with a four-span, steel girder structure with single shaft piers (non-skewed). The proposed alignment would be offset downstream of the existing bridge (north towards the railroad bridge) by approximately 7.6 m (25 ft). The new structure, which would be longer than the existing 152-m (500-ft) long highway bridge, would be long enough to provide the optimum hydraulic opening with consideration given to cost versus hydraulic benefit and additionally would accommodate pedestrian paths along each side of the river. The primary consideration regarding the hydraulic opening is the backwater created by the bridge. The optimum hydraulic opening would be determined assuming that the adjacent railroad bridge may be lengthened by others at some point in the future, thereby opening up the channel. The bridge design also includes features that would allow it to be lengthened in the future if needed. Specific design features, such as the length of the proposed structure, were not included in the EA to retain some flexibility for final design. Montana DepartmentofTransportation Page 1 Yellowstone River- NE of Livingston November 2008 BR 11-1(44)56 CN 4790 Finding ofNo SignificantImpact The bridge would include one 3.6-m (12-ft) travel lane in each direction and 2.4-m (8-ft) shoulders with a 3-m (10-ft) multi-use path along the south side of the bridge deck. The roadway approaches would also be replaced and would transition from the proposed bridge cross-section to the existing roadway cross-section. The multi-use path would extend from the bridge to the project limits. The intersection of Bennett Street and US 89 would be reconstructed to a T-intersection as described on page 2-7 of the attached EA. The construction of gravel parking lots in the project area would be considered as potential enhancements if funding and right-of-way (ROW) are available. It is anticipated that these parking areas would be on the south side of US 89; one on the east approach and one on the west approach of the bridge. The Selected Alternative meets the project purpose and need by improving the safety of the Yellowstone River Bridge. The Selected Alternative would improve safety for vehicles as well as pedestrians and bicyclists. Additionally, the Selected Alternative would provide a beneficial impact by increasing the hydraulic opening, better aligning the bridge to the Yellowstone River, and reducing the number of piers in the water. The Code of Federal Regulations, 23 CFR 771.119 (i), states; "If, at any point in the EA process, the Administration determines that the action is likely to have a significant impact on the environment, the preparation of an Environmental Impact Statement (EIS) will be required." As summarized in Table 1, many of the impacts associated with this project would be beneficial and provide an improvement compared with the No-Build Alternative. The potential adverse impacts identified include negligible to minor long-term impacts and negligible to moderate temporary impacts. No significant impacts were identified due to the proposed project, and therefore, the Preferred Alternative was selected for this project. The impacts of both the Selected Alternative and No-Build Alternative are summarized in Table 1 of this document.

The proposed improvements would also increase the hydraulic opening to provide better long-term hydraulic performance, improve the safety of boaters, and reduce the number of piers in the water. Table 1 summarizes the impacts of the No-Build and Selected Alternative for each of the impact topics discussed in the Environmental Assessment. Table 1.
