Exit list

On the east side of Sideling Hill, I-68 again interchanges with US 40 Scenic, at its eastern terminus at Woodmont Road. Here US 40 Scenic ends at a section of MD 144 separate from the section further west. Four miles (six kilometers) east of this interchange, I-68 ends at I-70 and U.S. Route 522 in the town of Hancock.[2]

I-68 crosses into Washington County at Sideling Hill Creek and ascends Sideling Hill. The road cut that was built into Sideling Hill for I-68 can be seen for several miles in each direction, and has become a tourist attraction as a result of the geologic structure exposed by the road cut.[43]

At exit 44 in east Cumberland, US 40 ALT meets the freeway and ends, and at exit 46, US 220 leaves I-68 and runs northward toward Bedford, Pennsylvania. I-68 continues across northeastern Allegany County, passing Rocky Gap State Park near exit 50. In northeastern Allegany County, the former US 40 bypassed by I-68 is designated as Maryland Route 144 (MD 144), with several exits from I-68 along the route. I-68 crosses several mountain ridges along this section of the highway, including Martins Mountain, Town Hill, and Green Ridge, and the highway passes through Green Ridge State Forest. East of Green Ridge State Forest, MD 144 ends at U.S. Route 40 Scenic (US 40 Scenic), another former section of US 40.[2]

Until 2008, signs at exit 43A in downtown Cumberland labeled the exit as providing access to West Virginia Route 28 Alternate (WV 28 ALT). Because of this, many truckers used this exit to get to West Virginia Route 28 (WV 28). This created problems on WV 28 ALT in Ridgeley, West Virginia, as trucks became stuck under a low railroad overpass, blocking traffic through Ridgeley. To reduce this problem, the Maryland State Highway Administration removed references to WV 28 ALT from guide signs for exit 43A and placed warning signs in Cumberland and on I-68 approaching Cumberland advising truckers to instead use exit 43B to Maryland Route 51, which allows them to connect to WV 28 via Virginia Avenue, bypassing the low overpass in Ridgeley.[42]

East of Frostburg, I-68 crosses a bridge above Spruce Hollow near Clarysville, passing over Maryland Route 55, which runs along the bottom of the valley. The freeway runs along the hillside above US 40 ALT in the valley formed by Braddock Run. Entering LaVale, I-68 has exits to US 40 ALT and MD 658 (signed southbound as U.S. Route 220 Truck). I-68 ascends Haystack Mountain, entering the city of Cumberland. This is the most congested section of the highway in Maryland. The speed limit on the highway drops from 70 miles per hour (110 km/h) in LaVale to 55 miles per hour (89 km/h) until the US 220 exit, and to 40 miles per hour (64 km/h) in downtown Cumberland.[2] This drop in the speed limit is due to several factors, including heavy congestion, closely spaced interchanges, and a sharp curve in the road, known locally as "Moose Curve," located at the bottom of Haystack Mountain. This section of the highway was originally built in the 1960s as the Cumberland Thruway, a bypass to the original path of U.S. Route 40 through Cumberland.[5]

After entering Allegany County, I-68 bypasses Frostburg to the south, with two exits, one to Midlothian Road (unsigned Maryland Route 736) and one to MD 36. Near the MD 36 exit is God's Ark of Safety church, which is known for its attempt to build a replica of Noah's Ark. This replica, which currently consists of a steel frame, can be seen from I-68.[41]

The traffic density on I-68 in Garrett County is rather sparse compared to that of Allegany County. At the Maryland—West Virginia state line, there is an annual average daily traffic of 11,581. This density increases to its highest point in Garrett County at exit 22, where US 219 leaves I-68; 19,551 vehicles per day drive through this section. At the Allegany County line, the traffic density decreases slightly to 18,408. In Allegany County, the vehicle count increases to 28,861 in LaVale, and to the freeway's peak of 46,191 at the first US 220 interchange (exit 42) in Cumberland. East of Cumberland, the vehicle count decreases to 16,551 at Martins Mountain and stays nearly constant to the eastern terminus of I-68 in Hancock.[2]

The section of I-68 west of Dans Mountain in Allegany County is located in the Allegheny Mountains, characterized in Garrett County by a series of uphill and downhill stretches along the freeway, each corresponding to a ridge that the freeway crosses. In Allegany County, the freeway crosses the Allegheny Front, where, from Savage Mountain to LaVale, the highway drops in elevation by 1,800 feet (550 m) in a distance of 9 miles (14 km).[39][40]

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 Maryland Route 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.[2] The roadway that used to be the surface alignment of US 40 parallels I-68 to Cumberland, and is now designated as US 40 ALT. I-68 crosses Negro Mountain, which was the highest point along the historic National Road that the freeway parallels east of Keysers Ridge. This is the source of the name of the freeway in Maryland: the National Freeway.[5] Three miles (five kilometers) east of Grantsville, US 219 leaves the National Freeway to run northward towards Meyersdale, Pennsylvania, while I-68 continues eastward, crossing Savage Mountain before entering Allegany County.[2]

The region of West Virginia through which the freeway passes is rural and mountainous. There are several sections that have steep grades, especially near the Cheat River Canyon, where there is a truck escape ramp in case trucks lose their brakes descending the steep grade.[37]

I-68 spans 112.6 miles (181.2 km)—81.1 miles (130.5 km) in Maryland and 31.5 miles (50.7 km) in West Virginia—connecting Cumberland, and Hancock.[34] I-68 is the main route connecting western Maryland to the rest of Maryland. I-68 is also advertised to drivers on I-70 as an "alternate route to Ohio and points west" by the Maryland State Highway Administration.[35]

West Virginia

A sign above the highway reads

I-68 begins at interchange 148 on I-79 near Morgantown and runs eastward, meeting with I-68 again runs eastward, interchanging with West Virginia Route 43, which provides access to Cheat Lake and Uniontown, Pennsylvania. Near this interchange, I-68 passes over Cheat Lake and climbs a steep ascent out of Cheat Canyon.[36]

Entering Preston County, the route interchanges with County Route 73/12, which provides access to I-68 crosses is more rural, with the only town along the route being Bruceton Mills. In Bruceton Mills, I-68 meets West Virginia Route 26. I-68 meets County Route 5 (Hazleton Road) at its last exit before entering Garrett County, Maryland.[36]

Route description

In May 2015, Maryland passed a law to increase the state's maximum speed limit. The speed limit was changed from 65 to 70 miles per hour (105 to 113 km/h). October 1 of the same year, this law was put into effect, making I-68's speed limit 70 mph except for the Cumberland area. Other Interstates in Maryland could also have their speed limit raised.[33] West Virginia's speed limit is already 70 mph.

On September 15, 2014, Cameron, then Cameron to Moundsville.[32]

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 West Virginia Route 2 (WV 2) in Moundsville. A 1989 proposal had suggested a toll road be built along this corridor.[30] In 2003, the Federal Highway Administration approved the extension, paving the way for federal funding and for the road to become part of the National Highway System on completion.[1] However, the project ran into problems due to lack of funds, and in 2008, West Virginia Governor Joe Manchin suggested dropping the project altogether, making construction of a westward extension of I-68 unlikely in the near future.[31]

Proposed extension

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 Baltimore. 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.[27] However, economic difficulties remain in Allegany and Garrett counties.[28] 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.[29]

Effect on surrounding region

On May 23, 2003, poor visibility due to fog was a major contributing factor to an 85-vehicle pileup on I-68 on Savage Mountain west of Frostburg. Two people were killed and nearly 100 people were injured in the pileup. Because of the extent of the wreckage on the road, I-68 remained blocked for 24 hours while the wreckage was cleared.[24] 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 ($275,000 in 2013[13]).[25][26] The system alerts drivers when visibility drops below 1,000 feet (300 m).[26]

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 $543,000 in 2013[13]), and prompted MDSHA to place signs prohibiting hazardous materials trucks from exiting at the Maryland Avenue exit.[21][22][23]

Incidents

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 Weston, West Virginia to Strasburg, Virginia.[19] This marks the third time that the US 48 number has been assigned to a highway, the first use being for a highway in California that existed in the 1920s.[20]

[5] This change took effect upon the completion of the last section of the National Freeway, on August 2, 1991.[18].I-68 designation to US 48's That same year, AASHTO approved changing [18].Interstate 595 to I-68 freeway from US 50, as the completion of the freeway neared, the possibility of the freeway being designated as an US 48 Though the National Freeway was designated as

Designation as I-68

In the 1980s, the focus of construction shifted to the east of Cumberland, where a 19-mile (31 km) section of the road still had not been completed. The first corridor for the construction to be approved by the Maryland State Highway Administration (MDSHA) ran south of U.S. Route 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.[5][16]

Much of the work in building the freeway was completed during the 1970s, with US 48 being opened from Vocke Road in LaVale to Maryland Route 36 in Frostburg on October 12, 1973, and to Maryland Route 546 on November 1, 1974.[5][15] On November 15, 1975, the West Virginia portion and a 14-mile (23 km) 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.[5]

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 $695 million in 2013[13])[14] The cost of building I-68 from Cumberland to the West Virginia state line came to $126 million ($775 million in 2013[13]); the portion between Cumberland and Sideling Hill cost $182 million ($396 million in 2013[13]); and the section at Sideling Hill cost $44 million ($96 million in 2013[13]).[5]

[12].I-68 It was this corridor that would eventually become [11][6]. At the time, there were no freeways along the corridor, though construction on the Cumberland Thruway began that year.Hancock, Maryland in I-70 In 1965, the Appalachian Development Act was passed, authorizing the establishment of the

Corridor E

Construction began on one of the first sections of what would become I-68, the Cumberland Thruway, on June 10, 1965.[6] This portion of the highway, which consists of a mile-long elevated bridge, was completed and opened to the public on December 5, 1966.[7] 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) by 1970.[8][9] 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.[10]

In the early 1960s, as the Interstate Highway System was being built throughout the United States, east-west travel through western Maryland was difficult, as US 40, the predecessor to I-68, was a two-lane country road with steep grades and hairpin turns.[5] In Cumberland, the traffic situation was particularly problematic, as the usage of US 40 exceeded the capacity of the city's narrow streets.[5] Traffic following US 40 through Cumberland entered through the Cumberland Narrows and followed Henderson Avenue to Baltimore Avenue. After the construction of I-68, this route through Cumberland became U.S. Route 40 Alternate.[2]

US 40 followed the route of the National Road through Pennsylvania and Maryland. The National Road was the first federally funded road built in the United States, authorized by Congress in 1806. Construction lasted from 1811 to 1837, establishing a road that extended from Cumberland to Vandalia, Illinois. Upon the establishment of the U.S. Highway system in 1926, the route of the National Road became part of U.S. Route 40.[4]

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.[3]

Prior to the construction of the freeway from Morgantown to Hancock, several different routes carried traffic across the region. West Virginia Route 73 extended from 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.
