Project officials provided media with a technical briefing earlier today, giving greater detail on the years-long construction process to come.
Traffic disruptions have already been occurring for several weeks at the intersection of Main Street and Broadway for the bridge-like traffic deck being installed over the span of the city block, which will allow for the excavation and construction of Mount Pleasant Station below it. These disruptions with reduced lanes will continue for about six months, until the deck is complete to establish four temporary travel lanes over the construction site.
The four other new subway stations along Broadway — Broadway-City Hall, Oak-VGH, South Granville, and Arbutus — will also each have four-lane traffic decks spanning a block or more over the station construction site, replicating street level. Traffic deck installation and excavation at these other stations will begin later this year.
