Freeway disruption for northern suburbs residents
January 18, 2010
Northern suburbs freeway users can expect some traffic disruptions as they head home this afternoon.
This will be the first big test of motorists’ readiness to use the outside emergency lane as a normal lane – in fact motorists wanting to exit at Karrinyup Road will need to get into the emergency lane at the beginning of the traffic management area.
The lane diversions will be in place for the next 4-5 weeks as the Public Transport Authority upgrades the safety barriers between the Mitchell Freeway’s northbound lanes and the railway line over a 600m stretch near Stirling Station. The program involves 1.5km of lane closures, diversions, and speed limitations which were set up between Hutton Street and Karrinyup Road over the weekend.
Though the median emergency lane and the adjoining fast lane are closed for the duration of the work, the full number of lanes is retained during the day by using the outer emergency stopping lane. Extra lanes may be closed in the evenings.
The work is being carried out between 7am and 5pm. If a night shift is required, it will be 7pm-5.30am. Depending on progress, work may also be undertaken on weekends.
Speed limitations apply even outside work times – through the area, the limit is reduced initially to 80kmh, then 60kmh on the approach to, and past the work site.
Joondalup Line train services are not affected though, for the duration of the work, all trains will be required to sound their horns as they approach the area.
The work is part of the PTA’s program to upgrade the barriers and make them consistent with the wire-rope and concrete barriers used along the Mandurah Line. This section will be concrete barriers.
The Mandurah Line safety barriers were adopted as a result of a comprehensive risk analysis undertaken by a specialist consultant in cooperation with Main Roads, and uniform barrier standards resulting from the American National Cooperative Research Program. In Australia, these standards have been adopted as AS/NZ 3845 (Road Safety Barriers).

Northern suburbs freeway users can expect some traffic disruptions over the next few weeks.
The Public Transport Authority will be upgrading the safety barriers which run between the Mitchell Freeway’s northbound lanes and the railway line over a 600m stretch near Stirling Station.
The five-week program involves 1.5km of lane closures and speed limitations which start next weekend (Saturday January 16) between Hutton Street and Karrinyup Road.
For the duration of the work, the median emergency lane and the adjoining fast lane will be closed. The usual full number of lanes will be retained during the day by using the outer emergency stopping lane, but extra lanes may be closed in the evenings.
Work will be undertaken from 7am to 5pm. If a night shift is required, it will be 7pm-5.30am. Depending on progress, work may also be undertaken on weekends.
Even outside work times, speed limitations will apply. Throughout the works, the speed limit will be reduced initially to 80kmh, then 60kmh on the approach to, and past the work site.
