Project Overview

This project will repair, line, or replace over 20 deteriorating culverts along a 24 mile stretch of US 2 between Chinook and Harlem. Culvert work will build a strong foundation for the complete reconstruction of the corridor planned within the next five years. Future projects will be more time and cost-efficient, as they will not need to engage in culvert work during construction.

Project Timeline and Cost

Construction on this project began on March 8th, 2021. It will take around three months for the culverts to be repaired or replaced, weather and other variables permitting. This project will cost $4,077,244, or just under $200,000 per mile.

Impacts on the Public

During construction, the traveling public should expect one-lane traffic with flaggers during regular work hours and two-lanes open during nights and weekends. Some culverts may require short gravel detours, which will be marked and flagged.

Motorists should also expect varied driving surfaces and speeds, as replaced culverts will be covered with gravel millings until paving can be completed. Please be alert to changing speeds and road conditions along this stretch of US 2.

MDT will work closely with the traveling public to ensure that wide loads, pedestrian and bicycle traffic, mail delivery, business accesses, and school bus routes are accommodated throughout construction.
