In the 1890s, an underpass (initially called "the subway") was built for Queen Street to accommodate growing east–west traffic; however, one was not built for Dufferin Street to connect it a block north of Queen. At the time, the area north of the railway line was heavily industrial and factories backed onto the tracks. North–south traffic was not expected nor planned for and the two sections of Dufferin were not connected. As automobiles arrived in Toronto around 1903, and for the next 107 years, vehicles looking to travel along Dufferin detoured around the closed section to Peel (east–west) and Gladstone (north–south), which became de facto sections of Dufferin. The detour was known locally as the "Dufferin Jog". The jog was eliminated in 2010 with the construction of a four-lane underpass beneath the railroad track, including public art and an amphitheatre-styled park with tiered gardens at the southwest corner of the underpass. This project was approved by city council in 2007, and work on extending the roadway began in July 2009. The underpass was opened on November 18, 2010. A further widening of the north side of the bridge was completed in 2016–2017 to support expanded GO Transit train service. The section of the east side of the bridge along Queen Street was built in 1897 as the Queen Street Subway. Wilson-Sheppard There is also currently a jog from Wilson to Sheppard, caused by the Downsview airbase built in 1929, which when built, was a rural area. Wilson Heights Blvd was built rerouting the northern section to head east avoiding the airport, with a jog at the southern section. In 1982, the northern section was rerouted again into Allen road. Today the path to connect the 2 sections is to go east on Wilson Avenue, north on Transit road, north on Allen road, of which funnels into Dufferin, and vice-versa. Italian community Dufferin Street has long been an important thoroughfare for Toronto's Italian community. An Italian neighbourhood developed around Dufferin and Davenport in the 1890s and soon became known as "little Little Italy". In the 1950s, Italian-Canadians from the main Little Italy around College Street and Grace Street headed northwest up Dufferin past St. Clair Avenue and were joined by a new wave of immigrants from Italy. By the 1960s, the Dufferin-St. Clair area (known as Corso Italia) had supplanted College-Grace Little Italy as the largest centre of Toronto's Italian community.
