U.S. Route 36 (US 36) is a part of the United States Numbered Highway System that runs from Rocky Mountain National Park, Colorado to Uhrichsville, Ohio.

Entering into Indiana, US 36 continues eastward in a straight line, serving Dana via SR 71.

Just west of Highland and Hillsdale, the route meets SR 63 at a parclo interchange.

After meandering eastward, the route intersects with US 41 in Rockville before entering the town's downtown area.

The next two exits (Sam Jones Expressway and I-70) serve the Indianapolis International Airport.

Between Lawrence and Pendleton, the routes intersect SR 234 in McCordsville, enter the communities of Woodbury, Fortville, and Ingalls.

[5] After US 36 was formed, the route in Indiana only traveled from the Illinois state line to US 40 (Washington Street) in Indianapolis.

[9] Later that year, US 36 was rerouted southward from Pendleton to Greenville along, in large part, its current routing.
