'''Delaware Route&nbsp;141''' ('''DE&nbsp;141''') is a state highway that serves as a western bypass of Wilmington, Delaware. Its southern terminus is at DE&nbsp;9 and DE&nbsp;273 in New Castle and its northern terminus is an interchange with U.S. Route&nbsp;202 (US&nbsp;202) and DE&nbsp;261 near Fairfax. The route heads north from DE&nbsp;9 and DE&nbsp;273 on four-lane divided Basin Road, becoming concurrent with US&nbsp;202 at an interchange with US&nbsp;13/US&nbsp;40 in Wilmington Manor, and passes to the east of Wilmington Airport. The highway becomes a freeway and reaches an interchange with Interstate&nbsp;95 (I-95), at which point US&nbsp;202 splits from DE&nbsp;141. The DE&nbsp;141 freeway continues north through Newport to Prices Corner. Here, the freeway segment ends and DE&nbsp;141 continues northeast as a surface road, with another brief freeway segment in Greenville. The route heads east across the Brandywine Creek on the Tyler-McConnell Bridge and continues to US&nbsp;202 and DE&nbsp;261.

What is now DE&nbsp;141 between New Castle and Newport was originally designated as part of DE&nbsp;41 in the 1930s. DE&nbsp;141 was designated as a surface bypass of Wilmington between New Castle and US&nbsp;202 north of Wilmington in the 1950s, running concurrent with DE&nbsp;41 south of Newport. DE&nbsp;41 was removed from DE&nbsp;141 by 1971. In the 1960s, DE&nbsp;141 was proposed to be upgraded to a freeway. Construction on the freeway segments between Newport and Prices Corner and in Greenville began in the 1970s and was completed around 1980. In the 1990s, several improvements were planned for DE&nbsp;141 north of Prices Corner, including grade separation at Rockland Road completed in 1997 and relocation of the northern terminus to its current location at an interchange with US&nbsp;202 and DE&nbsp;261 finished in 2007.

==Route description== thumb|left|US&nbsp;202/DE&nbsp;141 northbound at US&nbsp;13/US&nbsp;40 interchange in Wilmington Manor DE&nbsp;141 begins at an intersection with DE&nbsp;9 and the eastern terminus of DE&nbsp;273 west of the city of New Castle, where the road continues south as part of DE&nbsp;9. From the southern terminus, DE&nbsp;141 heads northwest on Basin Road, a four-lane divided highway. The road passes to the east of William Penn High School and continues past suburban homes and businesses. The route reaches a partial cloverleaf interchange with US&nbsp;13/US&nbsp;40 east of the Wilmington Airport, at which point US&nbsp;202 begins.<ref name="DE 2017 map"/><ref name="google"/>

From here, US&nbsp;202 runs concurrently with DE&nbsp;141, with the two routes heading between Wilmington Airport to the west and residential neighborhoods in Wilmington Manor to the east. The road passes between the Delaware Air National Guard's New Castle Air National Guard Base to the west and commercial establishments to the east, coming to a junction with the northern terminus of DE&nbsp;37. Past this junction, the median of US&nbsp;202/DE&nbsp;141 widens as the road intersects Airport Road.<ref name="DE 2017 map">{{Delaware road map|year=2017|access-date=August 18, 2019}}</ref><ref name="google">{{google maps |url=https://maps.google.com/maps?saddr=DE-141+N%2FE+Basin+Rd&daddr=39.7679562,-75.5977885+to:DE-141+N%2FPowder+Mill+Rd&hl=en&sll=39.773021,-75.546455&sspn=0.017646,0.042272&geocode=FUw7XQIdasF--w%3BFZTPXgIdJHh--ym3LpTcyf3GiTEielZ9e9n_6A%3BFYb1XgIdyER_-w&t=h&mra=ls&via=1&z=12|title=overview of Delaware Route 141|access-date=July 17, 2012}}</ref>

After intersecting Airport Road, US&nbsp;202/DE&nbsp;141 becomes a freeway. The road comes to an interchange with I-95 (Delaware Turnpike) and the southern terminus of I-295, at which point US&nbsp;202 splits from DE&nbsp;141 by continuing north along I-95. Past this interchange, DE&nbsp;141 widens to six lanes and has a southbound exit and entrance for South James Street and Old Airport Road before the median narrows. The freeway comes to a viaduct that crosses the Christina River into the town of Newport, where it heads near industrial areas and passes over Amtrak's Northeast Corridor railroad line.<ref name="DE 2017 map"/><ref name="google"/>

In Newport, the route has an interchange with DE&nbsp;4, at which point it narrows to four lanes and curves northwest with North James Street serving as a frontage road on both sides. The freeway widens back to six lanes and heads into a below-grade alignment that cuts through residential neighborhoods, leaving Newport. At this point, the frontage roads on both sides of the highway become Newport Gap Pike. DE&nbsp;141 reaches an interchange with DE&nbsp;62 in the community of Belvedere, where the Newport Gap Pike frontage road ends and the freeway narrows to four lanes. Following this interchange, the six-lane freeway rises to ground level and passes to the west of commercial development before coming to a bridge over CSX's Philadelphia Subdivision railroad line. The road runs near business areas and has a partial cloverleaf interchange with DE&nbsp;2 in Prices Corner.<ref name="DE 2017 map"/><ref name="google"/>

thumb|right|DE&nbsp;141 northbound past Faulkland Road west of WilmingtonAfter the DE&nbsp;2 interchange, the freeway section of DE&nbsp;141 ends and the route continues northeast on at-grade Centre Road, a four-lane divided highway. The road passes through suburban residential neighborhoods, crossing Little Mill Creek, and reaches an intersection with Faulkland Road. Following this intersection, the route heads north between the Ferris School to the west and DuPont's Chestnut Run Plaza research facility to the east. DE&nbsp;141 curves to the northeast and comes to a junction with DE&nbsp;48/DE&nbsp;100. Here, DE&nbsp;100 joins DE&nbsp;141 and the road runs to the west of commercial areas, curving north past the Barley Mill Road intersection. The roadway curves northeast and passes under an East Penn Railroad line before coming to a partial cloverleaf interchange with DE&nbsp;52 in Greenville. This interchange has no access from DE&nbsp;100/DE&nbsp;141 southbound to DE&nbsp;52 southbound or from DE&nbsp;52 to DE&nbsp;100/DE&nbsp;141 northbound. Past this interchange, the road curves east, with DE&nbsp;100 splitting from DE&nbsp;141 at an at-grade intersection by heading north on Montchanin Road. Montchanin Road heads south from this intersection to provide access to DE&nbsp;52.<ref name="DE 2017 map"/><ref name="google"/>

Past this intersection, DE&nbsp;141 continues east as four-lane divided Barley Mill Road, heading into wooded areas. The route becomes a two-lane undivided road as it passes to the south of the Hagley Museum and Library before crossing over the Brandywine Creek valley on the Tyler-McConnell Bridge. Past the bridge, DE&nbsp;141 turns northeast onto four-lane undivided Powder Mill Road, forming the northwestern boundary of the DuPont Experimental Station. The road widens into a divided highway and runs between the Nemours Mansion and Gardens to the east and the DuPont Country Club to the northwest. The route passes to the west of Nemours Children's Hospital, Delaware before coming to a bridge over Rockland Road. DE&nbsp;141 makes a sharp curve to the southeast and comes to an intersection where Powder Mill Road splits to the east and Childrens Drive heads southwest to provide access to Rockland Road and the children's hospital. The route continues southeast as it runs to the south of a JPMorgan Chase office complex. DE&nbsp;141 curves east, heading to the north of Alapocas Run State Park, and comes to its northern terminus at an interchange with US&nbsp;202 south of Fairfax in Blue Ball, where the road continues northeast as DE&nbsp;261.<ref name="DE 2017 map"/><ref name="google"/>

In 2016, DE&nbsp;141 had an annual average daily traffic count ranging from a high of 68,105&nbsp;vehicles at the DE&nbsp;4 interchange to a low of 15,466&nbsp;vehicles at the University Avenue intersection between DE&nbsp;9/DE&nbsp;273 and US&nbsp;13/US&nbsp;40.<ref name=DelDOT/> The entire length of DE&nbsp;141 is part of the National Highway System.<ref name="NHS">{{cite map|publisher=Federal Highway Administration|title=National Highway System: Delaware|url=https://www.fhwa.dot.gov/planning/national_highway_system/nhs_maps/delaware/de_delaware.pdf|year=2010|format=PDF|access-date=February 10, 2012|archive-date=January 16, 2014|archive-url=https://web.archive.org/web/20140116130055/http://www.fhwa.dot.gov/planning/national_highway_system/nhs_maps/delaware/de_delaware.pdf|url-status=live}}</ref>

thumb|left|DE&nbsp;141 northbound at the DE&nbsp;2 interchange in Prices Corner In 1992, an environmental assessment was approved for improving DE&nbsp;141 between DE&nbsp;2 and US&nbsp;202. Among the improvements called for were a six-lane bridge over the Brandywine Creek replacing the existing two-lane bridge, a new bridge over Rockland Road, and a new interchange with US&nbsp;202 and DE&nbsp;261.
