U.S. Route 50 (US 50) is a major east–west route of the U.S. Highway system, stretching just over 3,000 miles (4,800 km) from Ocean City, Maryland on the Atlantic Ocean to West Sacramento, California. In the U.S. state of Maryland, US 50 exists in two sections. The longer of these serves as a major route connecting Washington, D.C. with Ocean City; the latter is the eastern terminus of the highway. The other section passes through the southern end of Garrett County for less than 10 miles (16 km) as part of the Northwestern Turnpike, entering West Virginia at both ends. One notable section of US 50 is the dual-span Chesapeake Bay Bridge across Chesapeake Bay, which links central Maryland with the Eastern Shore region, allowing motorists to reach the beaches of Ocean City and Delaware.
US 50 has received numerous upgrades during its existence in Maryland, including the building of the John Hanson Highway (which is also the unsigned Interstate 595), its extension onto the Eastern Shore and replacement of U.S. Route 213 due to the construction of the Chesapeake Bay Bridge, and the full dualization of the eastern segment of the route. Many of the older alignments of US 50 are still part of the Maryland and US highway systems, such as U.S. Route 50 Business in Salisbury, Maryland. US 50 continues to be upgraded on the Eastern Shore to better accommodate beach travelers and locals alike.

George Washington Highway
US 50 leaves Preston County in West Virginia and enters the state of Maryland in Garrett County. US 50 is routed along the old Northwestern Turnpike, presently named George Washington Highway after George Washington. This section of US 50 is a quiet, rural highway with little traffic, which stands in sharp contrast to the other, longer section. US 50 intersects only two numbered highways along this stretch: US 219 in Red House, and MD 560 east of there.
Near the West Virginia community of Gormania, US 50 crosses the Potomac River and exits Maryland. It then passes through West Virginia, Virginia, and the District of Columbia, before reentering Maryland.
John Hanson Highway
US 50 exits the District as the John Hanson Highway, a freeway alignment extended from the east end of New York Avenue in Prince George's County. It instantly interchanges with the Baltimore-Washington Parkway at a hybrid interchange with a full cloverleaf and partial-Y elements. The B-W Parkway also allows access to Maryland Route 201. The freeway parallels the Orange Line of the Washington Metro as it weaves through the suburban area, interchanging with Maryland Route 202 and Maryland Route 410, then passes over the Orange Line and the New Carrollton Metro Station access road Maryland Route 950. It then meets a hybrid turbine interchange with Interstate 95 and 495, the Capital Beltway.
East of the interchange, US 50 enters the Interstate Highway System as the unsigned Interstate 595. The route is 10 lanes wide; beyond the MD 704 interchange, it narrows to eight lanes, with the innermost two being HOV lanes. Up to and slightly beyond the US 301/MD 3 interchange, the road surface is concrete; the roadway beyond there is asphalt. Within the US 301 interchange, the HOV lanes that began at the Capital Beltway come to an end, and US 301 joins US 50 and I-595, forming a three-route concurrency.
The central portion of the route runs through undeveloped forest and parkland, meeting Maryland Route 424 three miles (5 km) east of US 301. After meeting Interstate 97, the carriageways from I-97 straddle US 50 for a short distance before becoming MD 665, continuing toward downtown Annapolis as a direct freeway spur.
The route now runs through the Annapolis urban area, meeting MD 450 and MD 2. Continuing southeast, the route (which is now a four-route concurrency of US 50, US 301, I-595 and MD 2) eventually reaches the MD 70 interchange, where I-595 officially terminates.
Blue Star Memorial Highway
US 50 now becomes a Blue Star Memorial Highway, bearing this as its name past the MD 70 interchange. The route then passes over the Pearl Harbor Memorial Bridge over the Severn River and interchanges with the eastern end of MD 450. This interchanges also releases MD 2 from the concurrency, which travels northward to Baltimore. The US 50 and US 301 freeway pass through heavily wooded area, interchanging with few routes and offering rest stops along its final stretch through the Western Shore region. The freeway then interchanges with one last road, Oceanic Road, which passes over the toll plaza for the Chesapeake Bay Bridge.
The bridge's official name is the William Preston Lane, Jr. Memorial Bridge, and it connects Sandy Point on the Western Shore with Kent Island on the Eastern Shore. The bridge's asymmetrical dual spans are also a point of traffic congestion. The bridge raises US 50 and US 301 over two shipping channels, marked by the suspension and the through-truss spans of the structure. The bridge brings the two routes down on Kent Island, and quickly after, interchanges with Maryland Route 8 at a diamond interchange. After this interchange, the freeway portion on the Island continues, interchanging with many streets with sharp right-in/right-out ramps, until it meets the Kent Narrows Bridge, raising the routes over the Kent Narrows and bringing them down on the Eastern Shore's mainland.
Most of the interchanges along the final stretch of the freeway give access to Maryland Route 18, which parallels US 50 and 301 as a local route and a former alignment of the highway. After interchanging with Nesbit Road at another diamond interchange and the routes approach Queenstown, development ceases, and US 50 and US 301 separate at a half-trumpet interchange. US 301 continues straight along the carriageways, retaining the Blue Star Memorial Highway designation all the way to the Delaware state line. US 50, however, turns south using the ramps, and it picks up a new name: the Ocean Gateway.
Queen Anne's County
The Ocean Gateway name for US 50 is retained mostly for the remainder of its routing, changing only twice more for short distances. Continuing east from the US 50 and US 301 split, the highway becomes a four-lane, dual highway and instantly intersects Maryland Route 18 for the last time. It continues through open farmland, bearing southeast as it passes the northern terminus of Maryland Route 662 and Maryland Route 213, both former routings of the highway, which straddle Chesapeake College. US 50 then makes a curve, aiming almost perfectly south as it meets Maryland Route 404 atop the Queen Anne's/Talbot border.
US 50 continues to be signed as east/west, although it follows a north/south path. MD 662 weaves back and forth through open farmlands across this alignment through Talbot County as it approaches Easton, sometimes merging with it as well. North of Easton, Maryland Route 322 leaves US 50 to the west, which functions as a bypass of the town. US 50 passes east of the center of town, the speed limit dropping from 55MPH to 35MPH as it passes through the commercial sector. Outside of town, MD 322 meets US 50, and Maryland Route 565 runs concurrent with US 50 at the same intersection. MD 565 is another former alignment of US 50, possessing the residential development in the southern Talbot area. US 50 continues by Trappe, meeting the southern end of MD 565 before continuing to the Choptank River.
US 50 then passes over the Senator Frederick C. Malkus Bridge and enters Cambridge and Dorchester County, the speed limit once again dropping to 35 miles per hour (56 km/h), as the route returns to an east-west alignment. The entire section of US 50 in the city of Cambridge is named Sunburst Highway; this name is carried until Woods Road at the corporate boundaries of Cambridge. Here, the route's name returns to The Ocean Gateway, and later it picks up a concurrency with Maryland Route 16 for a short while outside the city, which ends in East New Market. From here, US 50 travels through mostly rural countryside in Dorchester County with several loops of older alignments of US 50 crossing the highway. As it dodges around Vienna on the Nanticoke River, the route intersects Old Ocean Gateway as a direct spur into the town. This road, formerly US 50 and then formerly MD 731, utilized a drawbridge to cross the river before the Nanticoke Memorial Bridge and Vienna Bypass opened in 1991. US 50 then interchanges with Maryland Route 331 at a partial cloverleaf and rises onto the Nanticoke Memorial Bridge, passing over the Nanticoke River.
US 50 then enters Wicomico County, and soon after passes by Mardela Springs. As it does so, it intersects Maryland Route 313 and Maryland Route 54. The route continues through open farmland in a general southeastern alignment until it approaches Salisbury. Northwest of the city, US 50 diverges onto the Salisbury Bypass, a freeway bypass forming a 3/4 beltway around the city. At this junction is US 50 Business, which goes directly through Salisbury. The Salisbury Bypass soon after interchanges with Naylor Mill Road, which allows westbound Business US 50 traffic to enter the freeway eastbound. The Bypass then passes through the Northwood business park on an earthen viaduct within the city limits, interchanging partially with Northwood Drive to grant access. Soon after this, US 50 interchanges with US 13 and Business US 13, picking up a concurrency with mainline US 13.
The two routes circle around the city to the northeast and eventually meet the interchange with US 13 and US 50 Business at a partial cloverleaf. Here, US 50 leaves the Bypass, and bears east along a four-lane, divided alignment. It passes by the campus of Wor-Wic Community College and continues through open farmland once more, intersecting various routes as it parallels MD 346 and bypasses Parsonsburg, Pittsville, and Willards, to the Pocomoke River, where the route leaves the county.
Shortly after entering the county, Maryland Route 90 branches off to the north, bypassing the town of Berlin and bearing toward the northern part of Ocean City, Shortly after MD 90, MD 346 crosses US 50 and heads into downtown Berlin. US 50 passes through northern Berlin, and meets a full cloverleaf interchange with US 113 in the process. This interchange also features railroad tracks, which cross two of the ramps. The route meets the end of MD 346 and continues through the heavily developed West Ocean City, Maryland, weaving across older alignments, notably Maryland Route 707. Maryland Route 589 also intersects the route, which leads to Ocean Pines and the last interchange with MD 90. US 50 finally passes over the Harry W. Kelly Memorial Bridge and the Sinepuxent Bay, touching down in the town of Ocean City, and meeting its national eastern terminus.
Although the route's ceremonial eastern terminus is at Maryland Route 528, Philadelphia Avenue, eastbound US 50 actually continues past MD 528 as North Division Street and ends at Maryland Route 378, Baltimore Avenue, a short distance from the Atlantic Ocean and Ocean City Boardwalk. From the westbound lanes as of June 2009, a sign can be seen displaying the distance to Sacramento, California as 3073 miles. This is an incorrect measure which is shared on California's end of US 50, as the route's length has been adjusted many times and shortened.
While the portion of U.S. 50 in Garrett County has remained largely unchanged, the eastern portion has changed significantly since the route was established in 1926.
Original 1926 plan
On the Western Shore, US 50 was on the alignment currently known as Maryland Route 450. It ended at Church Circle in Annapolis, near St. Anne's Church. Beyond the end of US 50 was a ferry which connected the route to what was then Maryland Route 17 on the Eastern Shore, in Talbot County.
Extension to the Eastern Shore
Just before the Chesapeake Bay Bridge's completion, in 1948, the route was extended to Ocean City. This extension brought the route across the bay via an existing ferry service, and US 50 replaced much of U.S. Route 213 and portions of Maryland Route 404 on the Eastern Shore. As a result of US 50 being routed onto the Eastern Shore, US 213 north of what is now US 50 was removed from the U.S. Highway system, and became the current Maryland Route 213 by the late 1970s. Once the bridge was completed in 1952, it replaced the ferry, which had been in service since the 1930s.
The John Hanson Highway, named for John Hanson, was the first section of US 50 to be upgraded to a freeway in Maryland. It was completed soon after the Bay Bridge was built, and the older alignment was redesignated Maryland Route 450. A slight extension of MD 450 was then created to reconnect it with US 50 near the present-day intersection with Maryland Route 2.
Dualization of US 50
High volumes of beach traffic as a result of the Chesapeake Bay Bridge called for further upgrades to the route. A very straight alignment south through Talbot County was later created, the old routing becoming Maryland Route 662 and Maryland Route 322. In Salisbury, US 50 was moved from Main Street to Church Street. In Worcester County, its present-day alignment was created, though only dualized east of US 113 in Berlin. Following this, in the mid-1960s, a new four-lane section of US 50 was completed between Salisbury at then-US 13 and Berlin at US 113, its old alignment east of East Main Street becoming Maryland Route 346, and Church Street being returned to the city. The rest of US 50 on the Eastern Shore was in the process of being dualized. This included an adjacent span of the Chesapeake Bay Bridge being built in 1973, widening the thoroughfare to an asymmetrical five lanes.
In 1991, just as the final two-lane section of US 50 was falling into severe disrepair, Vienna was bypassed to the northeast, completing the dualization of US 50 in Maryland. The old road was turned over to Wicomico County on its side (then privatized to Delmarva Power and Light in 2007), and the Dorchester street through Vienna became Maryland Route 731. Also at this time, two extra lanes were added to the John Hanson Highway in both directions as the Interstate 595 section was designated. Some overhead signs on and near the route do include space for the Interstate 595 shield, but the shields were never installed in order to reduce motorist confusion. The freeway portion was continued over to the Eastern Shore, from the Chesapeake Bay Bridge east to the US 50-301 split in Queenstown. The US 50/301 portion of the Blue Star Memorial Highway was upgraded to a freeway mostly during the late 1980s and early 1990s; prior to this it was only a divided highway with several local roads intersecting it. After being upgraded, many of these intersections became sharp right-in/right-out ramps.
The most recent upgrade to US 50 came in October 2002, when the Salisbury Bypass was extended to circle the north side of the city. US 50 was rerouted onto this, and the alignment within the city, already bypassed numerous times, became present-day US 50 Business.
There are currently plans to upgrade US 50 in Queen Anne's County to a full limited access freeway, the freeway portion ending at an interchange with Maryland Route 404 atop the Queen Anne's/Talbot County border. This comes along with plans to fully dualize the latter highway in the state of Maryland.
