[4] North of the Muncie Bypass, US 35 leaves SR 3 due west to Kokomo.

The road heads north from this point, as a six–lane major arterial passing through both commercial and residential areas.

Very soon after SR 205, the road enters Noble County, bypassing LaOtto and Avilla.

In Noble County, the route passes through rural farming land and parallels an abandoned railroad track on its way to Kendallville.

After the US 6 concurrency SR 3, becomes a two–lane rural highway heading due North, until Mongo where the road turns northwest.

The final route through the Fort Wayne metro area followed Indianapolis Road/Baer Road past the city's main airport (then known as Baer Field) to Lower Huntington Road in the Waynedale district of Fort Wayne.

Bluffton Road hugs the bank of the St. Mary's River before curving east and crossing it.

SR 1/SR 3 followed Rudisill Boulevard to Lafayette Street (US 27/US 33 northbound) and Clinton Street (US 27/US 33 southbound) at which points the state routes turned north to join the others heading to/from downtown Fort Wayne.

[9] In 1990, the four-lane upgrade from the DeKalb–Allen County line north of Huntertown to Kendallville was completed, bypassing the towns of LaOtto and Avilla.

This made SR 3 four lanes for the 25 miles (40 km) from I-69 in Fort Wayne to US 6 in Kendallville.

[10] In early 2010, construction began on SR 3 widening for about three miles (4.8 km) from Ludwig Road in Fort Wayne to Dupont Road on the north side of Fort Wayne.
