SB 1836 requires Tennessee's Department of Transportation to study the feasibility of building a new third bridge across the Mississippi River connecting to Arkansas, including related highway infrastructure. The study must be completed by February 1, 2027, and report findings on funding sources (federal, state, or local), development timing, and legislative recommendations.
