Motorists are being urged to remain patient as two major roadwork projects get under way in Truganina this month.
The intersection of Sayers and Forsyth roads will be upgraded, while traffic lights will be installed at Forsyth and Elmhurst roads.
The projects are being funded through developer contributions.
Traffic delays are expected while the works are carried out and drivers will be unable to turn right into Forsyth Road from Sayers Road.
