Infrastructure Upgrades in Billings: Perspectives on Ongoing Projects
Residents and commuters are adjusting to ongoing construction as Billings continues its multi-phase push to modernize local transportation and stormwater systems.
How we reported this

Billings is currently in the midst of several large-scale infrastructure projects aimed at improving connectivity and drainage across the city. As of 2026, the local landscape is defined by a series of ongoing developments that range from arterial roadway expansions to specialized environmental improvements. These projects, which affect daily commutes and neighborhood access, are being closely watched by those navigating the city's changing traffic patterns.
The Billings Bypass and Connectivity Improvements
The Billings Bypass remains a central focus for the city's long-term planning. According to information from Yellowstone County and Montana public works resources, the project is a six-phase arterial roadway initiative designed to connect Lockwood to Billings Heights across the Yellowstone River. Progress has been steady, with three phases now completed as of 2026. Drivers are already utilizing the Yellowstone River Bridge and the Five Mile Road segments, which are open to traffic. While these segments provide new routes, the project is moving into its next stage. The Johnson Lane Interchange segment is tentatively anticipated to begin construction in late 2026, with the full completion of the bypass projected for 2027-2028.
Separately, the Northwest Billings Connector and Marathon Loop are receiving significant investment. Billings secured an $11.6 million federal BUILD grant to finalize these routes, a move expected to create nearly 25 miles of continuous parkways in the vicinity of the airport. This development represents a shift toward more integrated regional infrastructure, aimed at providing better long-term logistics and accessibility near the terminal.
6th Street West and Airport Stormwater Upgrades
Work is also progressing in the south-central corridor. The 6th Street West underpass project resumed construction in June 2026, with local agencies aiming to address long-standing concerns regarding traffic flow and pedestrian safety. The project also includes critical updates to local stormwater facilities, which are intended to help the city manage seasonal runoff more effectively. Work on this site is currently expected to finish in summer 2026, marking a key milestone for commuters who frequently use the underpass.
Meanwhile, the Billings Logan International Airport is addressing environmental needs through the $1.5 million Stormwater Improvements Project. Funded by the Montana Infrastructure Sentinel Program, this initiative involves the expansion of Pond E. This project is specifically designed to handle runoff generated by new commercial aeronautical areas, ensuring that the facility's expansion does not negatively impact surrounding infrastructure or local water management systems. As these various projects move toward their respective completion dates, the city continues to coordinate these efforts to balance immediate traffic operational improvements with future regional growth.
