Project Overview

The Montana Department of Transportation (MDT) is developing plans to replace the two bridges that carry Interstate 90 over Quinn Creek Road. The bridges are located on Bozeman Hill Pass between Bozeman and Livingston in Park County.

During a routine inspection by the MDT Bridge Bureau, [hyperlink to “About MDT’s Bridge Management and Design Process” page] it was determined that the bridges have deteriorated to the point that maintenance is no longer practical and they need to be replaced. New bridges and additional safety improvements will continue to provide a safe crossing over Quinn Creek Road for many years.

The project includes:

  • Removing and replacing two overpass bridges.
  • Minor bridge approach roadway work.
  • Upgrading guardrails and improving drainage.
  • Installing a high-friction surface treatment to improve safety on the bridges.

The project is on an accelerated schedule to complete the design plans in 2021, with all major aspects of construction to be completed in 2022. Click here [hyperlink to Accelerated Bridge Construction page] for information about MDT's Accelerated Bridge Construction process.
