Arkansas HOT Lane Study Expected to Kick Off in Late 2017, in a report on central-state highway improvements, quotes a regional planning official as saying he expects a “high-occupancy-vehicle (HOV) toll-lane study” to begin “sometime in the latter part of this year.” The research, jointly undertaken by Metroplan and the Arkansas Highway and Transportation Department, will determine, “if we continue to add roadways, what kind of roadways are appropriate and how a new lane is utilized.” According to the website, the study will focus on highly traveled corridors such as I-30 and explore the costs of lane construction as well as tolling methods.
