Project Overview
The Montana Department of Transportation (MDT) is working with Sanbell (formerly Sanderson Stewart) and the City of Great Falls on the 9th Street NW Reconstruction project. This project is a joint effort between the City and MDT, nominated through the Transportation Improvement Program (TIP) process.
The project will reconstruct 9th Street NW, extending from Central Avenue W to the NW Bypass. As part of this effort, deteriorated pavement will be replaced, and storm drains will be upgraded to improve drainage. The signal at the intersection of 9th Street NW and the NW Bypass will also be upgraded. New curbs, gutters, Americans with Disabilities Act (ADA)-compliant curb ramps, and sidewalks will be installed or repaired throughout the project area to enhance accessibility. Additionally, the project plans to replace any trees affected by construction, with the addition of new boulevard trees.

Design Updates
In October 2025, representatives from the Montana Department of Transportation (MDT), Sanbell, and the City of Great Falls held a design review meeting to advance the 9th Street NW Reconstruction project.
Key meeting topics included road and traffic plans, cross sections, stormwater management, utility coordination, right-of-way needs, and the project cost estimate.
As the final design progresses, the project team has continued to refine key details such as incorporating stormwater treatment into the project’s drainage system, installing American with Disabilities Act (ADA)-compliant pedestrian push-buttons at the NW Bypass intersection, and ongoing right-of-way negotiations.
Project Timeline
This project began as the 9th Street NW/Watson Coulee Road project. The initiation and development of design alternatives process took place from 2021 to 2022. In 2022, the project was separated into two distinct projects: the 9th Street NW Reconstruction project and the Watson Coulee Road Reconstruction project.
Preliminary design for the 9th Street NW segment took place in 2023 and 2024. Final design is anticipated to continue through 2026. The project is currently anticipated to be let in January 2027, with construction planned to start in spring 2027, subject to funding availability and completion of the design.
Impacts on the Public
The project will impact parking along 9th Street NW. To improve drainage and pedestrian accessibility, new sidewalks, curb and gutters, and ADA curb ramps are proposed within the public right-of-way. Existing parking within the public right-of-way would be eliminated to accommodate these new pedestrian and drainage facilities.

Temporary impacts during construction may include reduced speeds, single-lane traffic, short-term street closures, and flagging operations.
Public Involvement
Updated on August 26, 2025.
On June 4, 2025, the Montana Department of Transportation (MDT), in partnership with Benchmark Public Affairs and Sanbell, hosted an in-person open house at West Elementary School in Great Falls. The event shared project updates, gathered community feedback, and answered questions about the upcoming 9th Street NW Reconstruction project.
Attendees visited five informational stations covering the project timeline, design features, parking and boulevard impacts, and opportunities for public comment. Large aerial maps and a project 1-pager helped illustrate planned improvements.
Feedback included strong support for the project’s safety enhancements and connectivity benefits, as well as suggestions on snow removal, driveway access, pedestrian accessibility, drainage improvements, and boulevard design. Many attendees also voiced interest in improved sidewalks, crosswalks, and pedestrian lighting.
The open house was promoted through social media, local newspaper, and radio ads, direct mail invitations, and neighborhood posts on Nextdoor. Media coverage appeared in both KRTV and The Electric.
Community feedback will continue to be collected as the design is finalized. To receive project updates, residents can sign up for email or text notifications. To submit a comment, email Ella at

Transportation Improvement Programs (TIPs): Metropolitan Planning Organizations (MPOs) in Billings, Great Falls, and Missoula developed Transportation Improvement Programs (TIPs) in partnership with local and state governments as part of MDT’s ongoing commitment to a comprehensive, cooperative transportation planning process.
Metropolitan Planning Organization (MPO): A group in an urban area of more than 50,000 people responsible for transportation planning. It is a partnership between a locale and the federal government that helps guide investment decisions for projects like this one. MPOs identify opportunities to improve safety, plan improvements, and analyze trends.
Right-of-Way: Right-of-way consists of the legal right to make a ‘way’ over, or use, someone else’s land. MDT may acquire right-of-way by buying a piece of land or purchasing an ‘easement’ for specific transportation or public utility use (fiber internet, natural gas, power lines, etc.). Most easements are on private property, though some are owned by the state, city, or county.
Easement: A right created by an agreement to cross or use someone else’s property for a specific purpose. Examples may include placing utilities through a specific property or the necessity to access another property.
