U.S. Route 50 in Maryland partially coincident with Salisbury Bypass
Route description
US 50 has two segments located in the state of Maryland totaling 149.67 mi (240.87 km). The 9.17-mile (14.76 km) western segment is a two-lane undivided road through rural mountain areas in Garrett County, heading into West Virginia at both ends. The 140.50-mile (226.11 km) eastern segment runs between the Washington, D.C., border in Prince George's County and the eastern terminus of the route at MD 528 and MD 378 in Ocean City as a multilane divided highway with some freeway segments. Between Washington, D.C., and Annapolis, US 50 follows a freeway called the John Hanson Highway, which is designated as unsigned I-595 between the interchanges with I-95/I-495 (the Capital Beltway) in New Carrollton and MD 70 in Annapolis. In Bowie, US 301 becomes concurrent with US 50 and unsigned I-595. East of Annapolis, US 50/US 301 continue east along a freeway called the Blue Star Memorial Highway. The two routes pass over the Chesapeake Bay on the Chesapeake Bay Bridge, linking the Western Shore and the Eastern Shore regions. After the bridge, US 50/US 301 head east across Kent Island before the freeway ends and the two routes split in Queenstown. From here, US 50 becomes an at-grade divided highway called Ocean Gateway and runs through rural areas of the Eastern Shore, heading south through Easton to Cambridge. The route turns southeast in Cambridge and continues through more rural land to Salisbury, which it bypasses to the north on a freeway called the Salisbury Bypass, a bypass road partly shared with US 13. Past Salisbury, US 50 becomes an at-grade divided highway again and continues east along the Ocean Gateway to Ocean City.US 50 serves as the main route between the Baltimore–Washington Metropolitan Area and the Eastern Shore, providing access to Ocean City and, by way of MD 404 and Delaware Route 404 (DE 404), the Delaware Beaches. As such, the route experiences heavy traffic in the summer months, with major congestion points including the Pearl Harbor Memorial Bridge over the Severn River in Annapolis, the Chesapeake Bay Bridge toll plaza, Easton, Cambridge, and the few miles leading into Ocean City. The peak travel periods in the summer are eastbound on Friday evenings, both directions on Saturday afternoons, and westbound on Sunday afternoons. The route is also a designated hurricane evacuation route out of Ocean City. US 50 in Maryland is a part of the main National Highway System between the Washington, D.C. border and the eastern terminus in Ocean City.US 50/I-595 has a high-occupancy vehicle lane (HOV lane) for carpools with 2 or more persons in each direction from west of I-95/I-495 to east of US 301, a distance of 7.5 miles (12.1 km). Unlike other HOV lanes in the Washington metropolitan area, which are only restricted during rush hours, the HOV lanes on US 50/I-595 are restricted at all times.US 50 comes to an eastbound exit and westbound entrance with US 50 Bus., which heads southeast into Salisbury along Ocean Gateway. At this point, US 50 becomes a four-lane freeway called the Salisbury Bypass that bypasses Salisbury to the north and east. From here, the route continues east and reaches a diamond interchange with Naylor Mill Road (US 50UA). Following this interchange, the freeway heads through wooded areas with some nearby residential development, coming to a bridge over the Wicomico River. The road passes through the Northwood business park on an earthen viaduct, crossing over the Delmarva Central Railroad's Delmarva Subdivision line before coming to an eastbound exit and westbound entrance with Northwood Drive. Past this interchange, US 50 comes to an interchange with US 13 and the northern terminus of US 13 Bus. at Salisbury Boulevard in a business area to the southwest of The Centre at Salisbury shopping mall. At this point, US 13 becomes concurrent with US 50 on the Salisbury Bypass, and the two routes head east through a mix of farmland and woodland with some homes. The freeway curves to the south and passes over the Delmarva Central Railroad's Willards Industrial Track line and MD 346 without an interchange. The road comes to a partial cloverleaf interchange with the eastern terminus of US 50 Bus. at Salisbury Parkway, at which point US 50 splits from the Salisbury Bypass to continue east as Ocean Gateway and US 13 continues south along the Salisbury Bypass.US 50 continues east along Ocean Gateway, a four-lane, at-grade divided highway with a wide median, and passes to the north of Arthur W. Perdue Stadium, the home ballpark of the Delmarva Shorebirds baseball team. The route intersects Hobbs Road and heads through commercial areas, with the John Deere Drive (MD 992A) frontage road parallel to the south. The road runs through woods and crosses Beaverdam Creek before heading near more commercial development, passing to the north of Wor–Wic Community College past the Walston Switch Road intersection. US 50 traverses forests before running through a mix of farmland and woodland, reaching an intersection with Parsonsburg Road, which leads north to Parsonsburg, and Eastside Road (MD 992B). The route continues east through more rural land and comes to a junction with the southern terminus of MD 353, which heads north into Pittsville. The road runs through farmland with some woods, with MD 346 parallel a distance to the north. US 50 reaches an intersection with MD 354, which heads north into Willards. From here, the route continues into wooded areas and crosses the Pocomoke River.Dualization
High volumes of beach traffic as a result of the Chesapeake Bay Bridge made further upgrades to the route necessary.  A very straight alignment south through Talbot County was built, the former alignment becoming MD 662.  In Salisbury, US 50 was moved from Main Street to Church Street.  In Worcester County, its present-day alignment was built, though only dualized east of US 113 in Berlin.  Following this, in the mid-1960s, the present 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 MD 346, and Church Street was returned to the city.  The rest of US 50 on the Eastern Shore was in the process of being dualized at this time.  This included the adjacent span of the Chesapeake Bay Bridge 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 the eastern section of US 50.  The drawbridge was then dismantled, and portions of the old road were designated MD 731.  The designations have been rolled back over time, however, and MD 731 is no longer signed.  The 1990s also saw two extra lanes added to the John Hanson Highway in both directions as it was upgraded to enter the Interstate Highway System, being granted the I-595 designation.  However, the I-595 shields were never installed on the highway; although the sign gantries installed during the upgrade contain space for the I-595 shields to be installed, this never happened to prevent motorist confusion, and as a result the designation is only used internally.  The freeway portion was extended to the Eastern Shore, from the Chesapeake Bay Bridge east to the US 50/US 301 split in Queenstown.  The US 50/US 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.
