Creation: An original US route that was extended south into Tennessee from Cincinnati by AASHO in Oct 1927, conditioned on Kentucky apprving US 27 replace the northern Ketucky US 25W (otherwise the Tennessee portion of this corridor would be designated US 125), running generally as it does now. Tennessee requested this as US 33. Kentucky met AASHO's conditions and AASHO assigned it as a US 27 extension instead. US 27 was assigned to a bit of US 41/TN 27 out of Chattanooga, plus all of TN 29.
Adjustments: In 1928, US 27 was removed from Old Dayton Pike in Red Bank; Old Dayton Pike at the TN 153 jct area; Springfield Rd (no longer crosses Chickamauga Cr) and Walden St in Soddy Daisy
Also in 1928, US 27 was removed from Liberty Rd to Liberty and TN 62 west to Wartburg; if US 27 used Kingston St/Old Gobey Rd/abandoned routing back across modern US 27 to old US 27 at Montgomery Rd near Wartburg, it stopped doing so in 1928.
By 1930, US 27 was extended south to 11th St in Chattanooga, replacing a bit of US 11/TN 2.
In 1931 or 1932, US 27 was removed from today's Old TN 302/TN 302 into Graysville and Old Graysville Rd to Dayton. It is uncertain how US 27 ran through Dayton then but best guess is Illinois/California/Delaware to TN 378.
Also in 1931 or 1932, US 27 was removed from Cemetery Rd/McGoffin Ave/Front St through Spring City; Edwards Ln north of Piney River bridge; all of the now-discontinuous Dixie Lee Hwy segments around Roddy.
It is unclear when US 27 was removed from Old Dayton Pike/Depot St in Soddy Daisy but I believe it was by 1932.

In 1934, US 27 was extended south through Chattanooga to the Georgia line at Rossville GA. It appears that US 41W from Rome GA north to Chattanooga was not recognized by Tennessee and the road from GA to downtown Chattanooga was not in the state highway system until US 27 replaced US 41W in 1934.

In 1947, US 27 was removed from Old Dayton Pike south of Bakewell and Old Dayton Rd north of Bakewell
In 1953, US 27 was removed from Kingston Ave/Molyneux St/Kingston Ave through Rockwood; Old kingston Hwy and Old Hwy 70/Post Oak Valley Rd esat of Rockwood; Headwaters Dr/Poland Hollow Rd at the Caney Creek Marina area; Old Hwy 70/Ruritan Rd west of Kingston
In 1957, US 27 was removed from Pansy Hill Rd in S Harriman; Emory Dr/Sewanee St/Morgan Ave in Harriman
In 1959, US 27 was removed from Sand Cut Rd out of Oneida; Tipple Rd; Poplar Ln; N. Old Hwy 27 in Winfield
In 1961, US 27 was moved onto the new Dayton Bypass, leaving behind TN 29 (now TN 378).
In 1963 or 1964, US 27 was rerouted at Harriman to follow TN 61 north 4 miles, then northwest as new primary routing to meet the old US 27 routing. The route from Harriman via the Oakdale area became TN 29A (now TN 328).
In 1967 (AASHO), US 27 was rerouted at Rockwood to follow TN 61 to Harriman, leaving behind US 70 overlay to Midtown and TN 29 (now Foust Hwy). By 1964, TDOT maps implied they had made this switch.

Between 1952-73, US 27 was removed from Tunnel Hill Rd to Old US Hwy 27 through Mountain View; Sycamore Ln (no longer crosses New River)
In 1975, US 27 was removed from Old US 27 stubs at the railroad crossing south of Sunbright and a small bit of Cumberland Mountain Cir nearby
About 1977, US 27 was moved from Dayton Blvd onto the new freeway between TN 153 and TN 319, with TN 29 using today's TN 319 between the old and new routing.
Also in 1977, US 27 was removed from Main St through Wartburg and Old Hwy 27 north out of Wartburg
Between 1974-83, US 27 was rerouted in Chattanooga to follow Market St past Main St, instead heading east on 20th/Washington/23rd back to Rossville Blvd. The old route had used Main east to Rossville Blvd.
About 1984, US 27 was moved from Dayton Pike onto new freeway north of today's TN 319 in Soddy Daisy.
In 1985 (AASHO), US 27 south was extended with US 127 north to the longtime freeway south across the Tennessee river to connect to I-124. This freeway had been TN 27 Spur up to that time. US 27 followed I-24 east back to TN 27 at Rossville Blvd. The old route through the city remained TN 27.
