U.S. Route 52 in West Virginia

The West Huntington Expressway is a controlled-access elevated highway that crosses the west end of Huntington WV. It was constructed in 1965 and originally signed as West Virginia Route 94 (WV 94). The first segment to open was a stub from I-64 to Jefferson Avenue in West Huntington in the fall of 1965. This included a bridge over a CSX railroad mainline. In the early 1970s, the expressway was extended northward across what is now the Nick Joe Rahall II Bridge across the Ohio River to US 52 and State Route 7 in Ohio.

Tolls were collected at the Ohio River bridge until the mid-1980s. The expressway has four lanes from I-64 to the US 60 interchange, where it drops to two lanes for the remainder of the highway, which includes the Ohio River bridge. The expressway was renumbered US 52 in 1979 when that highway was re-routed out of downtown Huntington to a new alignment on I-64 west to the Tolsia Highway south of Kenova.

The Tolsia Highway is defined as running from I-64 at Kenova to Corridor G (US 119) north of Williamson.[1] The name Tolsia takes the names from the first initials of the Tug, Ohio, Levisa, and Sandy Improvement Association.[2] US 52 originally took the path of WV 152, approximately 10 miles (16 km) east of the current alignment. In the mid-1960s, state funding was secured for a construction project along most of County Route 1 (CR 1), which ran along the Big Sandy River and Tug Fork River. The rebuilt CR 1 and CR 29 was renumbered as US 52 in 1979.

Portions of the 66-mile (106 km) highway have been widened to four lanes. In 1998, US 52 south of the I-64 interchange in Kenova was widened to four-lane highway standards to the access road for Tri-State Airport. In that same year, the Prichard bypass was opened to traffic with one interchange and one at-grade intersection. This four-mile (6.4 km) bypass includes very large rock cuts and a long and winding grade down a hill. In 2001, the four-lane highway was extended southward approximately two miles (3.2 km) to a stub interchange with WV 75. Also in that year, the four-lane highway near Prichard was extended northward for one-mile (1.6 km), removing some grades and curves along US 52. The extension was completed in 2002 at a cost of $9.6 million.

In 2001, the Crum segment of the Tolsia Highway opened to traffic. The highway begins just north of Crum at an incomplete diamond interchange and heads eastward towards CR 2. It has at-grade intersections with CR 52-47 and CR 52-31 along with a side road at the eastern terminus that takes traffic to CR 2. There are stubs for future bridges and ramps. Signage along this segment is minimal, with only a handful of arrows to designate the route. While the highway was built to four-lane standards, it is only striped for two.

In late 2002, Senator Robert C. Byrd received $20 million in funds to jump-start construction on the northern half of the Tolsia Highway. The money would be used to speed up construction on the 10-mile (16 km) link between Huntington and Prichard, serving several industrial parks and relieving two-lane US 52 of coal-truck congestion.

In 2003, survey and design of five miles (8.0 km) of four-lane US 52 from Prichard north to Cyrus were completed. Plans include an interchange and five bridge structures.

US 52 enters Kentucky twice along the Williamson, West Virginia bypass; bridging the Tug Fork River was preferred because it prevented the blasting of several hillsides in West Virginia. It was completed in 1996 as part of the Corridor G (US 119) project. The speed limit in West Virginia is 65 mph (105 km/h) but drops to 55 mph (89 km/h) in Kentucky.

The King Coal Highway is defined to run from WV 65 and Corridor G (US 119) near Belo, West Virginia, to I-77 at its US 52 interchange near Bluefield.[3] The Coalfields Expressway (US 121) and the Shawnee Expressway will connect to the King Coal Highway.

The travel time, currently over 120 minutes from Williamson to Bluefield, will be reduced to 87 minutes.[3] South of Ikes Fork, a two-hour trip to Bluefield will be reduced to 44 minutes.

A former strip mining site being converted for the King Coal Highway and Coalfields Expressway three-level diamond interchange. Taken in 2004, construction is not expected on the actual interchange itself for years.

Construction began in 1999 on the three-level diamond interchange on Indian Ridge near Welch that will facilitate traffic between the King Coal Highway (US 52, Interstate 73/74) and the Coalfields Expressway (US 121).

Initial site work was completed in 2003, with grading evident; this required the filling in of a large valley. It will also be the site of a new state prison along with future industrial development.

Future overpass for the King Coal Highway in Bluefield.

Work has progressed on the four-lane widening of US 52 in Mercer County just east of Bluefield. On November 24, a contract totaling $2,057,914 was let to move approximately 500,000 cubic yards (380,000 m³) of dirt and to grade and drain .22 miles from the recently completed $27 million interchange with Corridor Q (US 460) east of Bluefield to US 19 just north of James P. Bailey Lake. Six buildings will be demolished. This is the first of several projects that will extend the King Coal Highway to West Virginia Route 123 (Airport Road) north of Bluefield. Extending this project east, another contract was awarded December 15 and totals $1,371,251. The contract calls for more than 200,000 cubic yards (150,000 m³) of excavation to grade and drain .18 mile of the King Coal Highway from county route 25 just north of the US 460 interchange to south of the old Raleigh-Grayson Turnpike. 36 buildings will be demolished. A future contract will include a bridge over US 19 which will cost $15 million.[4][5]

Design work is being commenced on a 11-mile (18 km) segment of the King Coal Highway from Horsepen Mountain to Isaban and from the Mercer County Interchange to West Virginia Route 123/Airport Road. The work being done on a 2.5-mile (4.0 km) section of highway near Horsepen Mountain is being done by mining companies that will save taxpayers over $20 million.

The future of the project as a whole is very uncertain. In 2017, state lawmakers eliminated funding for the King Coal Highway Authority and its executive director as well as the Coalfields Expressway Authority. Both authorities were later shut down and local officials have been pushing for state lawmakers to reprioritize the construction of the King Coal Highway ever since.[6] In June 2023, the West Virginia Department of Transportation (WVDOT) announced that bids were let for the construction of the highway near Gilbert.[7] In August of the same year, design work began to extend the highway from its current construction at Airport Road in Bluefield northward towards Littlesburg Road.[8] However, the state still has not made the King Coal Highway one of its top priorities and doubt about whether the highway will ever be completed remains.[9]
