US 27 enters Indiana heading northwest from Ohio, parallel to CSX railroad track, in the town of West College Corner. In West College Corner the highway passes through the center of town, on a street named Liberty Avenue. The route continues northwest towards Liberty, as a two-lane rural highway passing through farmland. On the way to Liberty the road passes through Cottage Grove and crosses the Indiana Eastern Railroad. In Liberty the highway has an all-way stop at SR 44, this intersection is the southern end of the SR 44 concurrency. In the center of Liberty the two roads end the concurrency at a traffic light with SR 101, with US 27 heading north, SR 44 heading west and SR 101 heading south. US 27 leaves Liberty heading due north as a two-lane rural highway. The road enters Richmond from the south, with a series of curves and a traffic light at SR 227. US 27 and SR 227 begin a concurrency at this traffic light and both routes head north, heading for downtown Richmond. The concurrency passes over the Indiana Eastern Railroad tracks, as a four-lane undivided road. In downtown Richmond the roadway becomes one-way streets, begins after O street, with northbound on Ninth street and southbound of Eighth street. The two street head straight through downtown passing residential areas, before reaching commercial areas. At C Street the one-way pairs end and the road passes over Norfolk Southern railroad tracks. After the railroad tracks the concurrency with SR 227 ends with SR 227 heading northeast. US 27 continues northerly as a four-lane undivided highway. The road leaves Richmond having a single-point urban interchange, with Interstate 70 (I-70) and US 35. The route heads northwest from Richmond towards Portland, as a two-lane rural highway passing through farmland with a few houses.

At this traffic light the road becomes a four-lane divided highway, heading north towards Fort Wayne. On the way to Fort Wayne, the route passes through Decatur and at a traffic light a concurrency with US 33 begins. As the two highways head farther into Decatur US 224 joins the other two routes in a concurrency with three routes. US 224 leaves the concurrency heading due west for Huntington. The other two routes continue north-northwest leaving Decatur and heading for Fort Wayne.[4][5][6]

The concurrency with US 33 ends at a diamond interchange with I-469 on the south side of Fort Wayne.

The entire length of U.S. Route 27 in Indiana is included in the National Highway System (NHS).[7] The NHS is a network of highways that are identified as being most important for the economy, mobility and defense of the nation.[8] The highway is maintained by the Indiana Department of Transportation (INDOT) like all other U.S. Highways in the state. The department tracks the traffic volumes along all state highways as a part of its maintenance responsibilities using a metric called average annual daily traffic (AADT). This measurement is a calculation of the traffic level along a segment of roadway for any average day of the year. In 2010, INDOT figured that lowest traffic levels were 3,090 vehicles and 580 commercial vehicles used the highway daily from SR 28 to Jay County line. The peak traffic volumes were 41,790 vehicles and 2,570 commercial vehicles AADT along the section of US 27 just north of downtown Fort Wayne.[9]

The original route of US 27 was signed as three different state roads in 1918. Old SR 48 from Ohio state line to Liberty, Old SR 48 headed west on what is now known as SR 44. The section was from Liberty to Fort Wayne has Old SR 21. Old SR 46 was the original number given the a segment from Auburn to Angola. The section between the Old SR 21 and Old SR 46 was known as Custer Trail.[10][11] In 1924, the section north of Fort Wayne became Old SR 13 and went from Fort Wayne to the Michigan state line.[12][13] US 27 in Indiana is one of the original US Highways of 1926, then connecting Cheboygan, Michigan with Cincinnati through Fort Wayne.[3]

In November 1967, Indiana completed its northern segment of Interstate 69, the last incomplete section being opened between Angola and the Michigan/Indiana state line, supplanting US 27 as a through route. Interstate 69 north of Fort Wayne had been completed in stages, the designation of US 27 was moved to the interstate. Some segments of old US 27 remained as state highways with designations as SR 327, SR 427, and SR 127. Parts of these routes, comprising what had been the old surface road of US 27, were eventually returned to country governments. Within greater Fort Wayne, US 27 was diverted from Coldwater Road to Lima road. Then in 2001, INDOT removed the US 27 designation north of its interchange with I-69.

On March 9, 2007, legislation was introduced in the Indiana House of Representatives to designate US 27 as historic highway. Richmond, one of the cities through which US 27 passes, would have two historic highways passing through it as the original National Road (U.S. Route 40) runs through Richmond as well.
