Construction began in the summer of 2011. The first tunnel boring machine began tunnelling from Keelesdale Park (at Black Creek Drive and Eglinton Avenue) in the summer of 2013, working eastwards towards Avenue Road.
The Crosstown is a significant project with a long timeline, and works are completed in phases and in “rolling waves.” That is, we will focus on a section at a time. For example, there might be road closures and traffic diversions between Caledonia Road and Dufferin Street for several months while we construct headwalls in that area, but then we will move on to the next section. The entire project takes several years to complete, but we will not be occupying the same section for the entire time.
Generally, on the west side, we started tunnelling and station construction at Black Creek Drive, and we will work our way east. On the east side, we started at Brentcliffe Road and will work our way west, until the two meet at Yonge Street.
Currently (as of April 2014):
- The first pair of tunnel boring machines continues to tunnel eastward towards Yonge Street. Progress can be tracked on our TBM tracker.
- Headwall construction is completed for the future Keele and Caledonia underground stations, and is underway for the future Dufferin and Oakwood underground stations.
- Crews are preparing to install a jet grout plant at Chaplin, to prepare for headwall construction for the future Eglinton West, Bathurst and Chaplin underground stations.
- Crews are mobilizing east of Brentcliffe Road for the east tunnel launch shaft construction that will take place over 2014.
- Construction is beginning now on the extraction and launch shafts at Allen Road, near Eglinton West Station.
