Running parallel to [[Ontario Highway 400|Highway&nbsp;400]] approximately {{convert|15|km}} to the east, Highway&nbsp;404 extends {{convert|50.1|km|abbr=on}} on a north–south orientation between Highway&nbsp;401 and Woodbine Avenue. There are 16 interchanges along its length, mostly of the [[Partial cloverleaf interchange|Partial cloverleaf A4]] configuration. Exit numbers on the freeway start at 17, suggesting that the length of the Don Valley Parkway was considered in distance calculations; until 2017, there were no exit numbers posted on the DVP.<ref name="TA1">{{cite map |title = Toronto & Area |cartography = [[MapArt]] |publisher = Peter Heiler Ltd |year = 2011 |isbn = 978-1-55198-213-7 |pages = [https://archive.org/details/torontoarea0000unse/page/104 104, 320, 326, 332, 338, 344, 350, 355] |sections = T26–F30 |scale = 1:25,000 |url-access = registration |url = https://archive.org/details/torontoarea0000unse/page/104 }}</ref><ref name="plan" />

A continuation of the municipal-controlled DVP, the [[Ministry of Transportation of Ontario]] (MTO) jurisdiction over the freeway begins as the opposing directions of travel diverge south of the Highway 401 interchange.<ref group="note" name="note1">This demarcation line is visible on the highway as a change in pavement quality and the use of different high-mast lighting</ref>

Southbound, the freeway is divided into two carriageways, both of which provide access to the DVP. The outer carriageway also provides access from Sheppard and to both directions of Highway&nbsp;401, including the westbound express lanes, while the inner carriageway is intended for DVP-bound traffic. The HOV lane eventually merges with DVP-bound traffic, and also has an off-ramp via a tunnel to the Highway&nbsp;401 westbound collector lanes.<ref>{{cite web |title = Highway 404 Southbound HOV Lanes at Hwy 401/DVP |author = Ministry of Transportation of Ontario |publisher = Government of Ontario |url = http://www.mto.gov.on.ca/english/traveller/hov/image/detail.pdf |access-date = April 26, 2015 |archive-url = https://web.archive.org/web/20140904134017/http://www.mto.gov.on.ca/english/traveller/hov/image/detail.pdf |archive-date = September 4, 2014 }}</ref>

To the east of Highway&nbsp;404 is the Consumers Road office park. To the west and north of Sheppard Avenue is [[Fairview Mall]], which has its own connection with the southbound lanes attached to the Sheppard interchange.<ref name="TA1" />

[[File:Highway 404 at Stouffville.png|thumb|right|Highway 404 at Stouffville Road]]
At the interchange with Steeles Avenue which also includes a dedicated on-ramp from Woodbine Avenue (York Regional Road 8), the freeway enters the [[Regional Municipality of York]] where it diverges to the west before continuing north, running parallel to Woodbine Avenue. To the east are industrial units, while on the west are residential suburbs. This land-use persists north to the Highway&nbsp;407 ETR junction, a multi-level [[combination interchange]] with two [[Overpass|flyovers]]. At this point the freeway narrows and the central concrete barrier ends; a grass median taking its place between the opposing lanes. Immediately north of Highway&nbsp;407, the freeway interchanges with [[Ontario Highway 7|Highway&nbsp;7]], and due to the close spacing of these two interchanges, the northbound off-ramp to Highway&nbsp;7 is braided with the on-ramp from Highway&nbsp;407 (and vice versa with the southbound ramps) to avoid weaving. As the freeway crosses Highway&nbsp;7, the HOV lanes transition to standard through lanes, although as of 2020 construction is underway to extend the HOV lanes using the grass median. The freeway passes west of [[Buttonville Municipal Airport]] (decommissioned as of November 2023)<ref name="button">{{cite web |last = Larkin |first = F.K.

The land-use density continues to drop, with the appearance of some open spaces and farms interspersed with industrial and commercial buildings. By 19th&nbsp;Avenue, just north of the [[Honda]] Canada headquarters in Markham, the land-use is agricultural on both sides of Highway&nbsp;404. Highway 404 continues north, forming the eastern boundary of the municipalities of [[Richmond Hill, Ontario|Richmond Hill]], [[Aurora, Ontario|Aurora]] and [[Newmarket, Ontario|Newmarket]] and the western boundary of [[Whitchurch-Stouffville, Ontario|Whitchurch-Stouffville]]. North of Wellington Street, the highway reduces in width to four lanes, which is its configuration north through [[East Gwillimbury]].<ref name="backgrounder" /> The route continues, passing east of the community of [[Queensville, Ontario|Queensville]], where just a bit north Highway 404 will meet the future [[Bradford Bypass]], as it eventually curves northeast and terminates at an at-grade intersection with Woodbine Avenue immediately south of Ravenshoe Road (York Regional Road&nbsp;32).<ref name="TA1" />
 
The speed limit is {{convert|100|kph|abbr=on}} on most of its length, with the exception of the {{convert|16|km|abbr=on}} stretch between [[Newmarket, Ontario|Newmarket]] and the North end of the highway, where the speed limit was raised to {{convert|110|kph|abbr=on}} on April 22nd22, 2022.<ref>{{cite webpress release |first1 = Dakota |last1 = Brasier |first2 = Simisola |last2 = Ikotun |date = March 29, 2022 |url = https://news.ontario.ca/en/release/1001886/ontario-raising-highway-speed-limits |title = Ontario Raising Highway Speed Limits |publisher = Ministry of Transportation of Ontario |access-date = July 13, 2024 }}</ref>

=== Initial construction ===
[[File:Woodbine facing south.png|thumb|left|Facing south along Woodbine Avenue in 1965; the crossroad is Finch Avenue, which passes over the ten lane freeway that has since replaced this rural road]]
A freeway east of Highway 11 was planned as early as 1954, when the province extended [[Ontario Highway 48|Highway&nbsp;48]] south from [[Port Bolster, Ontario|Port Bolster]]. A large cloverleaf interchange was constructed with the Toronto Bypass, and plans formulated for a dual highway around the east side of Lake Simcoe, connecting with Highway{{nbsp}}11 near [[Orillia]] or [[Gravenhurst, Ontario|Gravenhurst]]. This route was dropped when Metropolitan Toronto began planning for the northern extension of the DVP in 1957, as [[subdivision (land)|subdivisions]] encroached upon [[Woodbine Avenue]] north of Highway{{nbsp}}401. The six-lane expressway was to follow the alignment of Woodbine from its southern terminus at [[Lawrence Avenue]] to north of [[Steeles Avenue]], where the [[Ministry of Transportation of Ontario|Department of Highways]] (DHO) would continue the road as a "new King's Highway".<ref name="plan">{{cite report |title = Don Valley Parkway Extension, Highway 401 to Steeles Avenue |publisher = Desjardines |year = 1957 }}</ref>

Design work on Highway{{nbsp}}404 started in 1973,<ref name="Davis" /> and construction began following the awarding of a [[Canadian dollar|C$]]6.9{{nbsp}}million contract in March 1976. This contract included construction of the Finch Avenue interchange, overpasses at McNicoll and Van Horne Avenues and {{convert|4.5|km|abbr=on}} of six-lane freeway between Sheppard and Steeles Avenues.<ref>{{cite news |title = Headache on the 401 |work = The Globe and Mail |location = Toronto |date = May 4, 1976 |page = 5 }}</ref><ref>{{cite report |title = Construction Program: King's and Secondary Highways |publisher = Ministry of Transportation and Communications, Ontario |year = 1975–1976 |page = xvii }}</ref>

The existing Metro-built segment of the DVP between Sheppard and Highway{{nbsp}}401 was designated as part of the new provincial freeway.
 
[[Image:Highway 404 2023.jpg|225px|right|thumb|Originally built as part of the Don Valley Parkway, the segment south of Sheppard Avenue became part of Highway{{nbsp}}404 in 1977.]]

The freeway was separated by a grass median with a steel box beam acting as a barrier between the lanes.

As originally built by Metro, the Sheppard Avenue interchange with the parkway was originally a [[Partial cloverleaf interchange#Configurations|Parclo AB2]], plus Fairview Mall Drive at the time ran only east-west directly north of the [[Fairview Mall|shopping centre]] and also had its own on/off-ramps from the southbound lanes of Highway&nbsp;404. In the 1980s the province removed the separate sets of Fairview Mall Drive and Sheppard Avenue ramps in favour of an on/off-ramp that fed directly to the shopping centre and an extension of Fairview Mall Drive whose eastbound lanes run south to meet with Sheppard Avenue.
 
Construction on the segment north of Bloomington to Aurora Sideroad was already in progress by this point.

=== 1997-2007 expansion ===
Studies and environmental assessments into various extensions began almost immediately after the completion of the route to Newmarket in 1989; it would take over a decade for any northward progression to take place. The completion of the route to Davis Drive was met with scorn as traffic in Newmarket rapidly increased as the [[Commuter town|bedroom community]] grew with the new highway access. Municipal officials warned prior to the opening of the route that major traffic delays would be faced along Davis Drive. Then-mayor [[Ray Twinney]] began an immediate push to widen Green Lane – at that time an unpaved rural route – into a bypass of the town.<ref>{{cite news |title = Highway 404 to Open to Newmarket Oct. 24 |first = Brian |last = Dexter |work = The Toronto Star |date = October 12, 1989 |department = North |page = 3 }}</ref>
Traffic delays were also compounded at the southern end of Toronto, where drivers whom had previously made use of [[Yonge Street]], [[Bayview Avenue]] or [[Leslie Street]] would shift to make use of the new freeway.<ref>{{cite news |title = New 404 Extension May Worsen Traffic |first = Peter |last = Howell |work = The Toronto Star |date = October 24, 1989 |department = News |page = A7 }}</ref><ref name="ts1992" />

By 1992, York Region was moving forward with plans to expand Green Lane into a four lane road, while the province was urged to consider extending Highway&nbsp;404 north to it, and eventually around the east side of Lake Simcoe.<ref name="ts1992">{{cite news |title = Province Urged to Study Link of Highways in North of Region |first = Brian |last = Dexter |work = The Toronto Star |date = March 26, 1992 |page = NY2 }}</ref> The province studied this and other options over the following years, before a formal announcement was made by Minister of Transportation [[Tony Clement]] on June 22, 1998, along with York Region chairman [[Bill Fisch]]. The plan called for an extension of Highway&nbsp;404 north to Green Lane, and widening of Highway&nbsp;9, the western extension of Davis Drive (now part of it after being [[Decommissioned highway|downloaded]] and redesignated as [[List of numbered roads in York Region|York Regional Road 31]] east of Highway 400) outside town, to five lanes between Highway&nbsp;400 and Bathurst Street.

In conjunction with the widening to add HOV lanes, improvements were made to the bottlenecked interchange with Highway&nbsp;401. This involved the construction of a two-lane on-ramp receiving traffic from the eastbound Highway&nbsp;401 express and collectors that would converge with Highway&nbsp;404 northbound without access to Sheppard Avenue, while the existing single lane on-ramp for that same movement was retained for Highway&nbsp;401 collector traffic to exit at Sheppard Avenue.<ref name="maps.google.ca"/> In early 2004, construction began on a new ramp from the Highway&nbsp;404 southbound HOV lane to the Highway&nbsp;401 westbound collectors, with the ramp consisting of a curved tunnel beneath the Highway&nbsp;404's southbound general traffic lanes. To accommodate the HOV ramp, the ramp for general traffic from Highway&nbsp;404 southbound to the Highway&nbsp;401 westbound collectors was shifted further west with its entry just under the Don Mills Road overpass while also realigned to permit a higher speed. On December 13, 2005, the southbound HOV lane was opened to traffic. This was one of the three original HOV lanes in Ontario; the other two HOV lanes were on [[Ontario Highway 403|Highway&nbsp;403]] in Mississauga.<ref name="HOV"/>

=== 2016-2024 expansion ===
On December 9, 2016, the MTO announced that the segment between [[Ontario Highway 407|Highway 407]] and Stouffville Road would be widened from six to eight lanes with the additional inner lanes to be used as HOV lanes.<ref name="thewidening">{{cite press release |title = Ontario and Canada Partnering to Expand Highway 404 |publisher = Government of Ontario |date = December 9, 2016 |url = https://news.ontario.ca/mto/en/2016/12/ontario-and-canada-partnering-to-expand-highway-404.html |access-date = December 11, 2016 }}</ref> Much of the work involved paving over the remainder of the grass median and erecting a concrete barrier.

== Future ==
Long term proposals by the province call for Highway 404 to be extended to [[Ontario Highway 12|Highway&nbsp;12]], between [[Sunderland, Ontario|Sunderland]] and [[Beaverton, Ontario|Beaverton]]. This extension would follow a new alignment to [[Port Bolster, Ontario|Port Bolster]], east of which the freeway would incorporate the existing two lanes of Highway&nbsp;48. It has drawn criticism from various environmental groups who claim it will only serve to accelerate [[urban sprawl]] north of Toronto.<ref>{{cite news |title = ((404 Extension a Highway to Sprawl, Environmental Groups Charge)) |first = Mark |last = Winfield |publisher = The Pembina Institute | date = April 13, 2006 |url = http://www.pembina.org/media-release/1220 |access-date = July 10, 2010 }}</ref><ref>{{cite web| |title = 2015 10-Year Roads and Transit Capital Construction Program |publisher = Regional Municipality of York |date = February 26, 2015 |url = http://www.york.ca/wps/wcm/connect/yorkpublic/0d954ef4-12b6-4ac7-931d-39a3d1269dff/2015+Approved+Roads_8_11_year_Ver2.pdf?MOD=AJPERES |access-date = June 9, 2015 }}</ref>
