context_page_description: U.S. Route 40 in the U.S. state of Maryland runs from Garrett County in western Maryland to Cecil County in the state's northeastern corner. With a total length of 221 miles, it is the longest numbered highway in Maryland. Almost half of the road overlaps or parallels with Interstate 68 or I-70, while the old alignment is generally known as US 40 Alternate, US 40 Scenic, or Maryland Route 144. West of Baltimore, in the Piedmont and
  Appalachian Mountains / Blue Ridge region of the Western Maryland panhandle of the small state, the portions where it does not overlap an Interstate highway are mostly two-lane roads. The portion northeast of Baltimore going toward Wilmington in northern Delaware and Philadelphia in southeastern Pennsylvania is a four-lane divided highway, known as the Pulaski Highway. This section crosses the Susquehanna River at the north end of the Chesapeake Bay on the Thomas J. Hatem Memorial Bridge.
context_section_description: Upon crossing the Patapsco River, US 40 enters Baltimore County and continues southeast along Baltimore National Pike through more forested areas of Patapsco Valley State Park before leaving the state park. The road heads into Catonsville, where it widens to six lanes and passes through a commercial strip of shopping centers and varieties of car dealerships and fast-food restaurants, curving to the east. The route crosses Rolling Road and turns to the east-northeast, continuing past a mix of homes and businesses. US 40 comes to an interchange with I-695 (Baltimore Beltway) and heads south of the former Westview Mall as it continues east through commercial areas. Farther east, the road passes through a mix of residential neighborhoods and shopping centers.
  US 40 leaves Baltimore County and enters the city of Baltimore, where it becomes maintained by the Baltimore Department of Transportation. The road continues east past homes in West Baltimore and comes to a junction with Edmonson Avenue, where the Baltimore National Pike name ends and the road name becomes Edmonson Avenue. A short distance later, the route intersects Cooks Lane. From here, the road heads east past commercial establishments and passes north of Edmondson-Westside High School and New Cathedral Cemetery before it continues into urban areas of rowhomes with some businesses. US 40 comes to an interchange with the western terminus of US 40 Truck at Hilton Parkway before it passes over CSX's Hanover Subdivision railroad line and Gwynns Falls. Following this, the route passes north of Western Cemetery before it turns southeast onto West Franklin Street. The road curves back to the east and continues between rowhomes to the north and commercial areas to the south. US 40 splits into the one-way pair of West Mulberry Street eastbound and Franklin Street westbound, carrying three lanes in each direction, and passes under Amtrak's Northeast Corridor railroad line at the West Baltimore station serving MARC's Penn Line. A short distance later, the route heads east onto a four-lane freeway stub located in a depressed alignment between West Mulberry Street and West Franklin Street, which serve as frontage roads; this freeway stub was formerly I-170. Along this freeway alignment, US 40 passes under US 1, which is accessed via an eastbound exit and westbound entrance with the frontage roads.  The freeway widens to six lanes as it continues east, coming to an interchange with Martin Luther King Jr. Boulevard.
  After this, the freeway ends and US 40 resumes along the one-way pair of West Mulberry Street eastbound and West Franklin Street westbound, carrying three lanes in each direction. The route intersects the northern terminus of MD 295, which is routed along the one-way pair of North Paca Street northbound and North Greene Street southbound, and the southern terminus of MD 129, which is routed along the one-way pair of North Paca Street northbound and Pennsylvania Avenue southbound. From here, US 40 passes south of the Seton Hill Historic District as it heads into the Mount Vernon neighborhood north of downtown Baltimore and continues east, crossing MTA Maryland's Baltimore Light RailLink at North Howard Street. The route crosses North Charles Street, at which point the name changes to East Mulberry Steet eastbound and East Franklin Street westbound. US 40 intersects the southbound direction of MD 2 at St. Paul Street before both directions rejoin along Orleans Street, a six-lane undivided road. The route heads onto the Orleans Street Viaduct, passing over the northbound direction of MD 2 (North Calvert Street) and I-83 in the Jones Falls stream valley. After this, the road becomes a divided highway and runs through urban areas of homes and businesses in East Baltimore, heading south of Paul Laurence Dunbar High School before passing through the campus of The Johns Hopkins Hospital. Past the hospital, US 40 becomes a four-lane undivided road and continues past rowhomes and some businesses. Farther east, the route intersects Pulaski Highway and heads east-northeast along f
