DUBLIN, Ohio — Gov. John Kasich says the state will invest $15 million to support research in self-driving highway technology along a 35-mile stretch of an Ohio road.

The Republican governor announced the investment Wednesday in conjunction with a self-driving truck made by Otto heading out on its first run along U.S. Route 33 between Dublin and East Liberty. A driver was going along as backup.

Officials say that four-lane section of Route 33 northwest of Columbus will become a corridor where technologies can be safely tested in real-life traffic, aided by a fiber-optic cable network and sensor systems slated for installation next year.

Leading automotive research centers and local governments in the region are also involved.

The self-driving truck also is slated to travel on the Ohio Turnpike later this week.
