Comment: VA 24 would be a terrific alternative to US 460 from Concord to Roanoke except for the twisty section west of Evington into Bedford County. The first time I drove this stretch I saw a pickup truck lodged in a tree from not making one of the sharp turns.
I think it is odd that VA 24 ended at the short VA 117 instead of carrying west to US 11.
The 1939 VDOT report on primary system development had recommended that VA 24 be decommissioned from Chamblissburg to US 29 and also from Rustburg to US 460.

Route 24: Emporia, North Carolina Line

VA 24 ran only from VA 12 (now US 58 Bus) Emporia southwest via SR 627 Brink Rd to the North Carolina Line.
In 1922 or 1923, VA 24 was rerouted from South Emporia south via Skippers to the North Carolina line near Pleasant Hill, NC.

In April 1924 (CTB), VA 24 was extended north as new routing 7.5 miles north of Emporia along Halifax Rd. A second piece of VA 24 was created running from Carson south 4 miles along Halifax Rd in Dinwiddie County. This second piece did not connect to any other part of the system.
In Feb 1925 (CTB), the Carson piece was extended noth 5 miles and the original piece was extended north 5 more miles.
In 1926, VA 24 was made continuous from VA 35 Templeton south to North Carolina via Emporia. There is no CTB reference and this may have been an act of legislature, as there is an CTB note in 1923 that this road was supposed to be part of the original state highway system but was erroneously left out.
In late 1926, US 17-1 was assigned to the entirety of VA 24. This had initially been proposed as US 15, which appears on the 1926 Official.
In late 1928, VA 24 was moved onto US 301's modern route (excluding parts affected by I-95 at overpasses/interchanges). This removed the highway entirely from Dinwiddie County. The original Halifax Road route is approximated: Halifax St north of today's US 58 Business, a bit of US 301, then SR 616 through Moonlight. VA 24 then followed SR 609 into Sussex County. After a bit of US 301, VA 24 then used SR 646 (with a bit of VA 139) through Jarratt. After more US 301, VA 24 used SR 640 northeast to SR 659 (old VA 40) then west back to modern 301 over mostly non-road today. VA 24 used VA 40 business in Stony Creek, then SR 618 into Dinwiddie County and on to Carson. VA 24 then picked up SR 604, then SR 621, then SR 605 which before I-95 used to connect to US 301 at Millpond Rd.
The 1928 reroute changed VA 24's northern endpoint from today's US 301/Millpond Ln jct south to US 301/VA 156/SR 668 jct just northeast of I-95.
In late 1932, US 17-1 was renumbered as US 301.
In July 1933, VA 24 was dropped from US 301.
