CHEYENNE, Wyo. (AP) - Lawmakers are considering an overhaul of Interstate 80 in southern Wyoming, starting with a major study of the highway.

The Wyoming Senate on Monday approved a bill that would require the Wyoming Department of Transportation to conduct a study of I-80 across the state and create a master project plan for the highway.

The study would include information on traffic leads, areas that are prone to closures and crashes, and how self-driving cars could affect the road.

The bill's sponsor Sen. Michael VonFlatern, R-Gillette, says new, improved data on I-80 is important. He also says the study would help Wyoming lay claim to any infrastructure efforts the federal government is planning.

The bill now heads to the House of Representatives for consideration.
