History
What is now DE 273 originally existed as a county road by 1920. Four years later, the portion of road through Newark was upgraded to a state highway while the road was paved between Hares Corner and New Castle. A year later, the section between Ogletown and Christiana was planned as a state highway while the section east of Basin Road was upgraded to a state highway. In 1930, the road between the Maryland border and Newark was built as a state highway, providing a shorter route to the Conowingo Dam

in Maryland. The following year, US 40 was designated to run on the portion of road between Hares Corner and New Castle, where it connected to a ferry across the Delaware River to Pennsville, New Jersey
Pennsville Township is a township in Salem County, in the U.S. state of New Jersey. As of the 2010 U.S. census, the township's population was 13,409, reflecting an increase of 215 (+1.6%) from the 13,194 counted in the 2000 census. The townshi ...
. Also by this time, all of present-day DE 273 was upgraded to a state highway except the portion of US 40 between Hares Corner and the Basin Road intersection in New Castle. In 1934, recommendations were made to upgrade US 40 to a state highway between Hares Corner and New Castle. The portion of US 40 between Hares Corner and New Castle was taken over by the state on July 1, 1935. Construction on upgrading this section began in 1936, with the project completed later that year. The same year, a bridge was constructed over a Pennsylvania Railroad

line (now the Jack A. Markell Trail) in New Castle.
DE 273 was designated to run from the Maryland border west of Newark east to US 13 and US 40 in Hares Corner by 1936, roughly following its current alignment. In Newark, the route ran concurrent with DE 2. By 1952, US 40 was realigned to use the Delaware Memorial Bridge

to cross the Delaware River, and DE 273 was extended east along the former alignment of US 40 on Frenchtown Road, Delaware Street, and Ferry Cut Off Street to end at present-day DE 9 at 6th Street in New Castle. In 1956, DE 2 and DE 273 were routed onto the one-way pair of Delaware Avenue eastbound and Main Street westbound in downtown Newark following an eastward extension of Delaware Avenue to the intersection between DE 2 and DE 273 east of the city.
By 1984, DE 9 was realigned to follow DE 273 east of the DE 141 intersection. DE 273 was realigned to bypass Christiana a year later, having previously followed Main Street through the community. DE 2 was routed to bypass Newark and DE 2 Bus. became concurrent with DE 273 through Newark by 1990. In 1997, DE 273 was moved to its current alignment in the Ogletown area, eliminating a short concurrency with DE 4 and involving the construction of an interchange with that route. The former alignment of DE 273 through Ogletown is known as Ogletown Road. The concurrent DE 2 Bus. designation was eliminated in 2013 as part of simplifying the route numbers in Newark. By 2015, DE 273 signage was cut back to its current eastern terminus, removing the concurrency with DE 9.
On March 15, 2021, a construction project began that will improve the interchange between DE 273 and I-95 by realigning ramps and widening DE 273 through the interchange.
