The construction of I-68 began in 1965 and continued for over 25 years, with completion on August 2, 1991. While the road was under construction, it was predicted that economic conditions would improve along the corridor for the five counties connected by I-68: Allegany, Garrett, and Washington in Maryland and Preston and Monongalia in West Virginia. The two largest cities connected by the highway are Morgantown, West Virginia, and Cumberland, Maryland.

History


Predecessors

Prior to the construction of the freeway from Morgantown to Hancock, several different routes carried traffic across the region. West Virginia Route 73 (WV 73) extended from
Bridgeport Bridgeport is the most populous city and a major port in the U.S. state of Connecticut. With a population of 148,654 in 2020, it is also the fifth-most populous in New England. Located in eastern Fairfield County at the mouth of the Pequonn ...
to Bruceton Mills, serving regions now served by I-79 (Bridgeport to Morgantown) and I-68 (Morgantown to Bruceton Mills). After the I-68 freeway, then known as US 48, was completed in West Virginia, the WV 73 designation was removed. Portions of the road still exist as County Route 73 (CR 73), CR , and CR 857. Between I-68's exit 10 at Cheat Lake and exit 15 at Coopers Rock, I-68 was largely built directly over old WV 73's roadbed. At Bruceton Mills, WV 73 ended at WV 26, which, from there, runs northeast into Pennsylvania, becoming Pennsylvania Route 281 at the state line and meeting US 40 north of the border. From there, eastbound traffic would follow US 40 into Maryland. I-68 now parallels US 40 through western Maryland. US 40 followed the route of the

Cumberland Thruway

and followed Henderson Avenue to Baltimore Avenue. After the construction of I-68, this route through Cumberland became US 40 Alternate (US 40 Alt.). Construction began on one of the first sections of what would become I-68, the Cumberland Thruway, on June10 , 1965. This portion of the highway, which consists of a mile-long (1.6 km) elevated bridge, was completed and opened to the public on December 5, 1966. The elevated highway connected Lee Street in west Cumberland to Maryland Avenue in east Cumberland, providing a quicker path for motorists traveling through the town on US 40 and US 220. The Cumberland Thruway was extended to US 220 and then to Vocke Road ( Maryland Route 658 (MD 658)) by 1970. Problems quickly emerged with the highway, especially near an area called "Moose Curve". At Moose Curve, the road curves sharply at the bottom of Haystack Mountain, and traffic accidents are common.


Corridor E

In 1965, the Appalachian Development Act was passed, authorizing the establishment of the

. At the time, there were no freeways along the corridor, though construction on the Cumberland Thruway began that year. It was this corridor that would eventually become I-68. The construction of Corridor E, which was also designated as US 48, took over 20 years and hundreds of millions of dollars to complete. The cost of completing the freeway in West Virginia has been estimated at $113 million (equivalent to $ in ). The cost of building I-68 from Cumberland to the West Virginia state line came to $126 million (equivalent to $ in ); the portion between Cumberland and

cost $182 million (equivalent to $ in ); and the section at Sideling Hill cost $44 million (equivalent to $ in ). Much of the work in building the freeway was completed during the 1970s, with US 48 opened from Vocke Road in LaVale to MD 36 in Frostburg on October 12, 1973, and to MD 546 on November 1, 1974. On November 15, 1975, the West Virginia portion and a portion from the West Virginia state line to Keysers Ridge in Maryland opened, followed by the remainder of the freeway in Garrett County on August 13, 1976. In the 1980s, the focus of construction shifted to the east of Cumberland, where a section of the road still had not been completed. The first corridor for the construction to be approved by the
Maryland State Highway Administration The Maryland State Highway Administration (abbreviated MDOT SHA or simply SHA) is the state transportation business unit responsible for maintaining Maryland's numbered highways outside Baltimore City. Formed originally under authority of the G ...
(MDSHA) ran south of US 40. This corridor would have bypassed towns in eastern Allegany County, such as Flintstone, leaving them without access to the freeway, and would have passed directly through Green Ridge State Forest, the largest state forest in Maryland. This proposed corridor provoked strong opposition, largely due to the environmental damage that would be caused by the road construction in Green Ridge State Forest. Environmental groups sued MDSHA in order to halt the planned construction, but the court ruled in favor of the State Highway Administration. In 1984, however, MDSHA reversed its earlier decision and chose an alignment that closely paralleled US 40, passing through Flintstone and to the north of Green Ridge State Forest. Construction on the final section of I-68 began May 25, 1987, and was completed on August 2, 1991.


Designation as I-68

Though the National Freeway was designated as US 48, as the completion of the freeway neared, the possibility of the freeway being designated as an

had been assigned the designation of I-68. MDSHA, however, later concluded that adding additional route shields to the US 50 freeway would not be helpful to drivers since about half the freeway already had two route designations (US 50 and US 301) and drivers on the freeway were already familiar with the US 50 designation. This made the designation to be applied to that freeway more flexible, and so, in 1989, the

(AASHTO), the organization composed of the various state departments of transportation that decides route numbering in the United States, approved MDSHA's request to renumber the US 50 freeway from I-68 to I-595. That same year, AASHTO approved changing US 48's designation to I-68. This change took effect upon the completion of the last section of the National Freeway on August 2, 1991. With the completion of I-68 and the change in its route number, the US 48 designation was removed. In 2002, AASHTO approved the establishment of a new US 48, this time for the Corridor H highway from

Incidents

Numerous accidents and incidents have occurred on I-68. On June 1, 1991, a gasoline tanker descending into downtown Cumberland from the east attempted to exit the freeway at exit 43D, Maryland Avenue. The tanker went out of control and overturned as the driver tried to go around the sharp turn at the exit. Gasoline began to leak from the damaged tanker, forcing the evacuation of a three-block area of Cumberland. Approximately 30 minutes later, the tanker exploded, setting eight houses on fire. The fire caused an estimated $250,000 in damages (equivalent to $ in ) and prompted MDSHA to place signs prohibiting hazardous materials trucks from exiting at the Maryland Avenue exit. On May 23, 2003, poor visibility due to fog was a major contributing factor to an 85-vehicle

on I-68 on Savage Mountain west of Frostburg. Two people were killed and nearly 100 people were injured. Because of the extent of the wreckage on the road, I-68 remained blocked for 24 hours while the wreckage was cleared. In the aftermath of the pileup, the question of how to deal with fog in the future was discussed. Though the cost of a fog warning system can be considerable, MDSHA installed such a system in 2005 at a cost of $230,000 (equivalent to $ in ). The system alerts drivers when visibility drops below .


Effect on surrounding region

One of the arguments in favor of the construction of I-68 was that the freeway would improve the poor economic conditions in western Maryland. The economy of the surrounding area has improved since the construction of the freeway, especially in Garrett County, where the freeway opened up the county to tourism from Washington, D.C., and

. Correspondingly, Garrett County saw a sharp increase in population and employment during and after the construction of the road, with full- and part-time employment increasing from 8,868 in 1976 to 15,334 in 1991. However, economic difficulties remain in Allegany and Garrett counties. There were concerns over loss of customers to businesses that have been cut off from the main highway due to the construction of the new alignment in the 1980s, leading to protests when then-Governor Harry Hughes visited the Sideling Hill road cut when it was opened.


Proposed extension

In the 1990s, there was discussion about a future westward extension to I-68. Such an extension would connect the western terminus of I-68 in Morgantown to WV 2 in Moundsville. A 1989 proposal had suggested a toll road be built along this corridor. In 2003, the
Federal Highway Administration The Federal Highway Administration (FHWA) is a division of the United States Department of Transportation that specializes in highway transportation. The agency's major activities are grouped into two programs, the Federal-aid Highway Program ...
(FHWA) approved the extension, paving the way for federal funding and for the road to become part of the National Highway System on completion. However, the project ran into problems due to lack of funds, and, in 2008, West Virginia Governor

Maryland

After entering Garrett County, I-68 continues its run through rural areas, crossing the northern part of the county. The terrain through this area consists of ridges that extend from southwest to northeast, with I-68 crossing the ridges through its east–west run. The first exit in Maryland is at MD 42 in Friendsville. I-68 ascends Keysers Ridge, where it meets US 40 and US 219, both of which join the highway at Keysers Ridge.
