I-94 Rest Area Study


The study examined existing and proposed rest areas within the I-90 corridor from Big Timber to Columbus and the I-94 corridor from Billings to Miles City. The study assessed the current condition of rest area locations, determined the feasibility of upgrading existing facilities, and prioritized proposed improvements. Findings and recommendations from the study were discussed at a public meeting, including the proposal to construct a new rest area at Fort Keogh.
