Construction Details

Bridge deck construction projects will be improving bridges along the Interstate 15 corridor from Helena into Great Falls this summer. We plan to minimize impacts to your commute and travel by providing timely updates and helpful details throughout the construction.

 

Interstate 15 Bridge Deck Improvements

In an effort to our keep good roads good, bridge deck improvements are scheduled to begin in mid-April and continue throughout the summer months. While construction is underway, travelers should anticipate changes in lane configurations, which will include traffic crossovers. Traffic will continue in both directions throughout the entire project. Delays to accommodate wide loads are possible, so we recommend that commuters plan additional travel time. Signage will be present to alert drivers to these conditions in advance of construction areas.

Interstate 315 Bridge Deck Improvement: Exit 0 Bridge at Marketplace

As a main route into the heart of Great Falls, the Exit 0 Bridge at Marketplace (Interstate 315 bridge structure between the Fox Farm signal and 14th Street) is an important lifeline for our community. This summer, construction will improve the Exit 0 bridge deck. Construction improvements will extend the life of the structure for up to 20 years.

Construction will begin mid-June and continue throughout the summer. Commuters and travelers are advised to plan ahead, especially during peak travel hours. Delays and congestion, specifically at the Fox Farm signal, may occur. Safety is the top priority during this construction project. There will be no impact to business access.
