Corridor Q is a highway in the U.S. states of Kentucky, Virginia, and West Virginia. It is part of the Appalachian Development Highway System and U.S. Route 460. Corridor Q runs from Corridor B (US 23/US 119) near Pikeville, Kentucky easterly to Interstate 81 in Christiansburg, Virginia.
Corridor Q does not meet any ADHS Corridors other than B, but it meets the planned Coalfields Expressway (U.S. Route 121) near Grundy, Virginia, the King Coal Highway (U.S. Route 52) in Bluefield, West Virginia, and Interstate 77 just to the east near Princeton. At its west end, traffic can continue northwesterly along Corridor B, Corridor R, Corridor I, and Interstate 64 to reach Lexington, Kentucky. The part of Corridor Q east of Bluefield is part of the I-73/74 North-South Corridor.
Corridor Q in Kentucky exists between Corridor B/US 23/US 119 at Yeager to the VA 80 near Breaks, Virginia. The corridor is expected to continue southeastward to the Coalfields Expressway approximately five-miles from the Kentucky state line. The new four-lane relocation of US 460 will include interchanges at US 23, Greasy Creek Road, KY 195 and at KY 80.
- Section 1: US 460 will depart from US 23 at Yeager and head southeast towards Stagger Fork. An at-grade intersection will be constructed at US 23, however it will be grade-separated in 2008. This section is currently under construction .
- Section 2: US 460 will extend eastward from Stagger Fork to Greasy Creek Road. A diamond interchange is planned for the eastern terminus of this section. This section is currently under construction 
- Section 3: The highway will extend further east from the Greasy Creek Road interchange to Snake Branch. This section is currently under construction .
- Section 4
- Section 5: The highway will continue eastward from the KY 195 interchange to Laurel Branch. The KY 195 interchange will be constructed during this phase. Construction will begin on this segment in 2009.
- Section 6
- Section 6A: This section extends from Laurel Branch to Pond Creek. Construction will begin on this segment in 2010.
- Section 6B: The route is extended east to Russell Fork. Construction will begin on this segment in 2011.
- Section 6C: This involves the construction of a bridge spanning Russell Fork and KY 80. Construction will begin on this segment in 2012.
- Section 7
- Section 7JMB: This involves the construction of a bridge over Russell Fork just west of Elkhorn City for John Moore Branch Road. Construction on this segment is underway.
- Section 7A: This section of US 460 extends from KY 80 to 3,000 feet (910 m) east of Beaver Creek. It includes an interchange with KY 80. Construction on this segment began in 2006.
- Section 7B: This extends from 3,000 feet (910 m) east of Beaver Creek to KY 1373. Construction on this segment began in 2006.
- Section 8: US 460 will extend east from KY 1373 to the Virginia state line. Construction will begin on this segment in 2007.
- Section 9V: This section, constructed by the Virginia Department of Transportation, will include the connection to VA 80. Construction will begin on this segment in 2010.
In the early 1970s, the former Virginian Railway right-of-way along the north bank of the New River eastward from a point near the VA-WV state line near Glen Lyn to Narrows was acquired by VDOT's predecessor agency from the Norfolk and Western Railway to enable four-laning of the highway through the narrow space between the river and rocky bluffs. (The N&W main line follows the south bank through this area). Along this stretch of highway (From the WV-VA state line until Pearisburg, VA.) the speed limit fluctuates multiple times, with posted limits quickly dropping to as low as 40 miles per hour. Police presence along the highway is especially high in the town of Narrows, VA. (Where the speed limit is 40 miles per hour).
Traveling further east, U.S. 460 climbs the mountain. After leaving Giles County and entering Montgomery County, spectacular views of the Blacksburg countryside are visible on the south side of the mountain. As the highway begins the long descent down the mountain, travelers enter Blacksburg's limits. There are several ways to access Downtown Blacksburg from U.S. 460 (Listed in order as if traveling Eastbound).
- North Main Street (Business 460): 4-way intersection (Farmingdale Lane to the right, North Main Street to the left
- Toms Creek Road: Limited-access interchange with right exit. This exit is convenient for destinations on Patrick Henry Drive (The Village Phase I and II, Terrace View, Pheasant Run Crossing, Hunter's Ridge, Pheasant Run, Collegiate Suites, University Terrace) and also destinations on the northern end of University City Blvd.
- Prices Fork Road: Limited-access interchange with right-hand exit. This exit is convenient for destinations such as Lodging (Hilton Garden Inn, Hawthorne Suites, The Inn At Virginia Tech), the University Mall area, which is on the southern end of University City Blvd. (Math Emporium, Off-Campus Bookstore, numerous dining establishments) and off-campus housing (Hethwood, Smith's Landing). From the west (U.S. 460), Prices Fork Road is the preferred way to travel into Downtown Blacksburg or one of two ways to access the Virginia Tech campus.
- Southgate Drive: 3-way intersection with a traffic signal. Runs directly onto the Virginia Tech campus. Preferred entrance point for the athletic complex and Lane Stadium. Also, the best entrance for the Virginia Tech Airport and Corporate Research Center (Both are located on Tech Center Drive, along with Virginia College of Osteopathic Medicine (VCOM))
At this point, U.S. 460 travelers are now in the vicinity of Christiansburg.
- South Main Street (Business 460): Limited-access interchange with right-hand exit Heading north on Main Street will take you back towards Blacksburg. Heading south takes travelers past Montgomery Regional Hospital and into the business district of Christiansburg.
After passing the South Main Street exit, there are a few more exits for the Christiansburg area. Traffic congestion is sometimes an issue due to the numerous businesses in town and near the mall area.
Presently, U.S. 460 Business (South Main Street, but becomes North Franklin Street upon entering Christiansburg) runs through downtown Christiansburg and U.S. 460 Bypass runs just outside of the town.
Future plans include converting the Smart Road into a 5.7 mile limited-access highway, connecting Blacksburg directly to I-81. The VDOT Projects and Studies website for the Smart Road project states under Phase 1, "Western end has large turnaround for normal-speed turns by test vehicles. Will link with Route 460 Business and Bypass and new Blacksburg interchange for 460 Bypass (under construction) for regular traffic when phase 3 completed". At this point in time, ramps are partially complete, but inaccessible.
The section from the Virginia state line east to US 19/WV 112 opened in 1977 at a distance of 5.38 miles (8.66 km). It forms a southern bypass of Bluefield and features a small concurrency with US 52; it is signed as US 460 otherwise. During the same year, the section of US 19 and US 460 that run concurrent between WV 112 and CR 19-33 at Maple Acres opened (MP 5.38 to MP 8.68). The segment between Maple Acres and the US 19 intersection southwest of Princeton opened in 1967 (MP 8.68 to 10.70). The corridor between WV 112 and the northern US 19 intersection is signed both US 19 and US 460 (MP 5.38 to 10.70).
In 1978, a southern bypass of Princeton opened from the northern US 19 intersection southwest of the city to the WV 104 intersection just west of Interstate 77 (MP 10.73 to MP 15.35). The four-lane road at the Interstate 77 junction opened nine-years prior (MP 15.35 to MP 15.84).
The only modification to the highway, with the exclusion of various traffic signal additions between Bluefield and Princeton, is an incomplete interchange with the King Coal Highway at the eastern US 52 junction east of Bluefield. The $27 million interchange opened in the early 2000s with the four-lane upgrade of US 52 between US 460 and Interstate 77.
