I 90 Manhattan to Belgrade and Bozeman Hill Guardrail
The Montana Department of Transportation (MDT) is improving Interstate 90 as part of two construction projects between Manhattan and Livingston. The projects include rehabilitating the pavement and upgrading guardrails to prolong the life of the roadway and improve safety. Construction is anticipated to take place beginning in May and be completed in the fall 2021.
