I-90, SH-41 TO US-95 WIDENING CONSTRUCTION

The five miles of I-90 from SH-41 to US-95 are the most heavily traveled and congested in the corridor. Design is complete and construction is anticipated to start in summer 2025.  ​

​Improvements

 

  • Add two lanes in each direction, for a total of four lanes eastbound and four lanes westbound.

  • Replace and widen bridges over Huetter Road, Atlas Road, and Prairie Trail. 

  • Realign and improve impacted sections of Prairie Trail and Centennial Trail.

  • Lengthen existing interchange on- and off-ramps at SH-41, Northwest Boulevard, and US-95 to allow for safer merging with I-90 mainline traffic.

The I-90 widening improvements between SH-41 and US-95 are anticipated to start in summer 2025 and take four construction seasons to complete.

 

Work will take place during day and night hours and conditions will include:​

  • Two-lane traffic maintained in each direction during daytime hours.  

  • Reduced speed limits and increased fines in work zones for safety. 

  • Short-term detours on Huetter and Atlas Roads during bridge construction.  

  • Ramp closures for up to one week for widening and reconstruction, as needed.

  • Reduced shoulder widths throughout the project area.  

  • Intermittent impacts to the trails including detours and gravel surfaces.  

Please note, construction schedules and impacts are subject to change.
