Highway 144 was created by renumbering Highway 544 in April 1965. This was done in preparation for an extension of the short secondary highway from
Cartier to Timmins, and was completed in 1970. In the mid-1980s, a new route was constructed which allowed Highway 144 to bypass the urban core of Sudbury, known as the Northwest Bypass.
Route description
Highway 144 is long, lying between its southern terminus at an
interchange with
Highway 17 west of
Lively and its northern terminus at an intersection with
Highway 101 west of downtown Timmins.

Cartier is the only community located directly on the highway anywhere north of Sudbury's northerly city limits, although

History
Prior to 1964, Highway 144 was numbered as Highway 544 and extended from Sudbury to Cartier.
Construction began in that year on a new route connecting Sudbury to Timmins, with work commencing at both ends as well as from Gogama. The highway number was changed in April 1965; the upgrade from secondary to primary highway reflected the proposed route's importance in linking two major urban centres.
Despite this, the portion of the route of Highway 544 between Windy Lake and Cartier was bypassed by a new
alignment

; the old route is still known as Old Highway 544 or Old Cartier Road.
The new highway was fully opened to traffic by premier

John Parmenter Robarts (January 11, 1917 – October 18, 1982) was a Canadian lawyer and politician who served as the 17th premier of Ontario from 1961 to 1971. He was a member of the Progressive Conservative Party of Ontario.

on September 25, 1970.
Until some point between 1974 and 1977, Highway 144 passed through the
INCO mine property north of Copper Cliff and entered Sudbury along Spruce Street and Regent Street.
Realignments between Sudbury and
Azilda resulted in a shorter routing that is today known as
Sudbury Municipal Road 35.
Despite this, planning was underway throughout the 1970s to construct several bypasses around Sudbury, including the
Southwest Bypass of Highway 17, as well as the Northwest Bypass between it and Chelmsford. In early 1983, contracts were tendered for the grading of the northern section within what was then the town of
Rayside-Balfour. The project was completed by the end of the year, after which a second contract was awarded to grade a further . The final grading contract, which included the interchange at Highway 17, was awarded in 1985 and completed in mid-1986. The entire bypass was paved shortly thereafter and opened in 1987.
Future
In recent years, heavy traffic has been reported along the route through Chelmsford and
Dowling, with an average daily traffic volume of 19,200 vehicles in 2002. The
Ministry of Transportation has announced a preliminary study into potential improvements to the route between Chelmsford and Dowling, which may include the possibility of a full bypass realignment.
The City of Greater Sudbury had widened Municipal Road 35 between the eastern intersection of Municipal Road 21 (Notre Dame Street) in Azilda to Highway 144 in Chelmsford to four lanes. Construction began in the fall of 2018 with a culvert replacement contract. The completion of widening of Municipal Road 35 was expected to be completed in 2021 and was fully completed in 2022.
