Timber Bridges - Glasgow Area logo

Project Overview

MDT is proactively investing in improving aging infrastructure in Montana. These actions not only safeguard the public, but they maintain Montana’s vital connections. The Timber Bridges-Glasgow Area project will replace 15 bridges in northeast Montana, impacting US 2 between Hinsdale and Glasgow, MT 24 between Glasgow and Opheim, MT 248 between Opheim and Scobey, and MT 251 between Poplar and Flaxville. The project involves replacing some of the aging and deteriorating timber bridges with new structures and will reconstruct the adjacent roadways as necessary.

Why is this project important?

The goal of this project is to keep Montana’s bridges safe, resilient, economical, and reliable. The MDT Bridge Bureau is responsible for over 5,000 bridges in the state. As an agency, they inspect, evaluate, replace, rehabilitate, and preserve structures under their jurisdiction.

The aging timber structures are deteriorating and have limited serviceable life remaining. MDT has determined that the most cost-effective approach is to replace the bridge bundle through a Design-Build contract.

What does this mean to me?

The design phase means this is your chance to provide us information and points of view that are important to how you and your communities use these bridges and the roadways connected to them. Working together, we will have opportunities for you to provide input as we develop our plans for each bridge.

Process and Anticipated Schedule 

Phase 1 Preliminary Design – October 2020 – September 2021

Gather preliminary information at each bridge site
Develop reasonable solutions for replacing the existing bridges
Provide MDT with a summary of all information gathered
MDT to solicit Design Build Request for Proposals in Fall 2021

Phase 2 Final Design and Construction – October 2021 – Fall 2023

Design-Build Team will develop final construction plans by Spring 2022
Design-Build Team will perform construction from Spring 2022 – Fall 2023

Project Cost

Preliminary cost estimates are being developed as part of the Phase 1 Preliminary Design. 

Engineer to English 

Phase 1 Preliminary Engineering – Phase 1 services are needed to understand and analyze the project, as well as formulate design for all sites. The information provided through the Phase 1 analysis will be utilized in the Design-Build process. Phase 1 will provide numerous investigation, analysis, and design services, including: surveys; hydraulic analysis; geotechnical exploration; environmental investigation; concept roadway and bridge design; public involvement; cost estimation and risk analysis; traffic management and construction phasing recommendations; R/W design, and potentially R/W acquisition.

Design-Build – A project delivery system that combines the design and construction services for a project into a single contract. Teamwork between the design engineer and contractor helps project teams to develop better solutions, reduce project costs, maintain quality, and expedite project delivery. The process for Design-Build projects is different from MDT’s typical project development approach; however, all work is completed in accordance with state and federal design standards, specifications and contract administration practices. Design-Build can be a helpful tool for completing unique and challenging projects like this one!

Stay Involved

Public involvement is important to MDT and the success of the project. The community will be notified about public involvement opportunities through this website, local media, mailings, social media channels and other means as the project progresses.  MDT encourages questions and comments about the project. You can submit them through the MDT Comment page or directly to our team here.
