) The Mitchell Freeway is the northern section of
State Route 2. It commences at the northern end of the
Narrows Bridge,
Perth, continuing from
Kwinana Freeway, and terminates north of the
satellite city of
Joondalup at Romeo Road,
Alkimos. All intersections with the freeway are via
grade separated interchanges. The speed limit is except in central Perth, where the limit is . South of Hepburn Avenue, the freeway has 3 to 5 lanes in each direction. From that point north, there are mostly two lanes in each direction, expanding to three lanes between Hodges Drive and Shenton Avenue. For much of its length the
median strip of the freeway also houses the
Yanchep line, with nine of the line's stations and the
Nowergup depot built on the strip. Additionally, a
shared pedestrian and bicycle path is built alongside most of the freeway.
Perth and West Perth The section near the
Perth city centre, within the
City of Perth local government area (LGA), features many partial access interchanges. The Narrows Interchange is located just north of the Narrows Bridge, on the eastern edge of
Kings Park. This is a
hybrid interchange connecting the freeway with
Mounts Bay Road and
Riverside Drive, over a distance of . There is complete access to and from Mounts Bay Road via a standard northbound exit ramp and looped ramps for the other movements. There is a
partial Y-interchange incorporated for direct access to and from Riverside Drive via a southbound exit ramp and a northbound entrance ramp. All other traffic movements must be made via Mounts Bay Road. The Riverside Drive entrance ramp merges with the Mounts Bay Road northbound entrance ramp. The southbound exit ramp is similarly shared, before diverging for three destinations: Mounts Bay Road, Riverside Drive, and the
Perth Convention and Exhibition Centre car park. The main northbound exit to
Hay Street is via an access road, which begins on the Mounts Bay Road exit ramp. The access road rejoins the freeway as an outside lane on the shared Riverside Drive and Mounts Bay Road entrance ramp. The Hay Street exit ramp, a short distance later, can be accessed from the two outermost lanes. This allows the traffic entering the freeway from the ramp to continue north or exit at Hay Street without
weaving. The freeway continues north-westerly for , The next interchange, after , is with
Erindale Road. It is another half diamond interchange, with only northbound exit and southbound entrance ramps. Beyond Erindale Road, the suburb to the east of the freeway is
Balcatta, and further north is
Reid Highway, with the southbound and westbound-to-northbound entry ramps looped. Balcatta Road joins the intersection of the southbound ramps with Reid Highway. Reid Highway, together with
Tonkin Highway, provides a
limited-access route to
Perth Airport. North of Reid Highway, the Mitchell Freeway divides
Carine to west from
Hamersley to the east. There is no access to the next major road,
Beach Road. It forms the border between the City of Stirling and
City of Joondalup LGAs; as well as between Carine and
Duncraig west of the freeway, and Hamersley and
Warwick to the east.
Warwick Road's interchange is north of Reid Highway. It is a standard diamond interchange, but weaving is required between Reid Highway and Warwick Road due to the short distance between the interchanges.
Greenwood is located north of Warwick Road and east of the freeway. The following two interchanges, after and respectively, are with
Hepburn Avenue and
Whitfords Avenue. The Hepburn Avenue interchange is located at the corners of Duncraig, Greenwood,
Kingsley, and
Padbury; while the Whitfords Avenue interchange is located at the corner of Kingsley, Padbury,
Cragie, and
Woodvale. Each interchange also provides access for the railway stations in the median (
Greenwood and
Whitfords respectively) via the southbound entry ramps, which are
two-way north of the carparks' entrances. North of here, over a distance of , are standard diamond interchanges with
Ocean Reef Road,
Hodges Drive, and
Shenton Avenue, which provide access to
Joondalup city centre, and
Joondalup Health Campus, east of the freeway. West of the freeway are the suburbs of
Heathridge,
Connolly and
Currambine.
Edgewater station lies just to the north of the Ocean Reef Road interchange (road access via
Joondalup Drive), with the railway deviating to the east from the median just south of Hodges Drive to stop at
Joondalup station. north of the Shenton Avenue interchange, the railway line re-enters the freeway median just prior to passing under
Moore Drive. Both the freeway and railway then pass over
Burns Beach Road, further north with the
Currambine station lying to the south. The diamond interchange with Burns Beach Road is the northernmost fully signalised interchange on the freeway and lies at the corner of Currambine, Joondalup,
Kinross and
Neerabup. The next interchange, after , is with
Neerabup Road and is a hybrid interchange where the western side is a teardrop roundabout common to
dogbone interchanges while the eastern side is a full roundabout similar to a
dumbbell interchange. The next interchange is reached north at
Hester Avenue at a partial
dogbone interchange. After Hester Avenue, the northbound and southbound carriageways split and pass around the
Nowergup railway depot before reaching the next interchange at Lukin Drive, after which the railway again deviates from the freeway median, this time to the west to continue on to
Butler station and beyond to
Yanchep. The next interchange is with Butler Boulevard, and later, the freeway terminates at Romeo Road. Access to areas further north is provided by
Marmion Avenue to the west of the terminus or via
Wanneroo Road to the east. ==History==
