Starting Sunday, July 13, the eastbound Interstate 90 (I-90) ramps will be closed for night work between approximately 7 PM and 6 AM. Those entering and exiting the interstate at Zoo Drive will need to use an alternate route. This night closure is expected to last about one week.
Project Overview
The Montana Department of Transportation (MDT) plans to improve traffic operations and enhance safety features on the Zoo Drive corridor, in Billings. The Zoo Drive Improvements project will occur along Zoo Drive between Shiloh Road and South Frontage Road.
Planned improvements include:
- Widening and reconfiguring Zoo Drive to a five-lane roadway with two lanes in each direction and a center turn-lane.
- Widening and reconfiguring a section of Gabel Road between Circle K and the intersection with Zoo Drive to a five-lane layout with four southbound lanes. This will include a second left-turn lane from Gabel Road onto Zoo Drive, toward Interstate 90 (I-90).
- Intersection and traffic signal improvements.
- Pavement marking modifications.
- Median modifications.
- Additional connectivity for pedestrians and bicyclists.
- Americans with Disabilities Act (ADA) upgrades.
- Widening a segment of the eastbound I-90 ramps.
- Milling and paving the roadway.
MDT has selected Knife River as the primary contractor for the Zoo Drive Improvements project. Construction is expected to begin this summer with anticipated completion in the fall of 2025.
