TN 61 Harriman to Clinton 1924 Official

TN 61 extended east to Blaine 1929 Official

In the 1933-36 timeframe, Norris Lake was created. This affected TN 61 in Union County. The 1939 Union County map shows a gap in TN 61 from the Anderson Line to just north of today's TN 170 (although State Officials do not show a gap). The original route used today's Dock Rd and abandoned underwater routing.
In 1938, TN 61 was given a much more direct route from Harriman to Oliver Springs. The old route used Webster Rd (except TN 61 ran much closer to the Emroy River bend) to Little Emory; went due east across abnadoned routing over Little Emory River; Clax Gap Rd to Clacks Gap; Mays Valley Rd and Dyllis Rd through Dyllis; Old Harriman Hwy through Jonesville and Orchard View, picking up Kingston Ave into Oliver Springs.
By 1939, TN 61 east was truncated from US 11W to US 11W's new routing in Blaine, leaving behind Indian Ridge Rd (since altered).

About 1946, TN 61 was given its direct routing from the north edge of Oak Ridge to where TN 95 now ends. The old route was removed from the highway system. It used a bit of TN 62; Old Knoxvile Hwy; TN 62 to just past Outer Dr; abandoned routing s of TN 62 to near Hillside Rd where it used the east end of Hickory Ln and Raleigh Rd before picking up today's TN 95 which it used all the way to its end except for Elza Rd near the tie-in back to new TN 61. This may also have been when TN 61 was removed from Old Tacora Hills Rd west of Clinton and Hillcrest St/W Broad St within Clinton.
About 1947, TN 61 was given its current routing through northern Harriman. The old route used the removed RR bridge on Whitier Ave and the zig-zaggy Old Roane St all the way out of town.
In 1953 or 1954, TN 61 was extended southwest to US 70 Rockwood.
