From this morning
It has with tunnel construction but station stops didn't start until 2016 and the surface section started in 2017. I should also add REM to the bet too.Interesting bet. Lots of similarities between the two, but with Crosstown being roughly 50% underground, 50% longer & with twice the stops, I'll guess Valley Line finishes first. Crosstown is a straight shot as apposed to the Valley Lines winding path and elevations but it seems some of the more challenging aspects that slowed the Valley Lines schedule have passed, hopefully we can play catch-up?
Didn't Crosstown start 2011/12?
1) The segments are getting support on temporary travelling formwork and then post tensioned ( stressed) back to the previous segment when the traveller moves to the next segment.
2) We have 1 more segment (5m) on each side to complete in January before we attach the cables. The cables will then go up as each segment moves out across the river.
3) The tower is at full height now. The formwork and hoarding surrounding the tower will be removed before the holiday break and the full tower will be visible.
The typical height for LRT power lines is six metres. The high load corridor features nine-metre power-line clearance needed for the large vehicles and their payloads. Those oversized loads would be too tall to pass under the lower LRT power lines.
Here is the design team’s solution:
The X-wing is located at the intersection of Whitemud Drive and 75th Street near the Operations and Maintenance Facility.
The X-wing, named by the Valley Line team’s Star Wars fans for its resemblance to the Rebel Alliance starfighter, is the first of its kind in North America.
Its steel arms will raise LRT power lines up to 14 metres so that oversized loads can safely travel below. This line-lifting process, which will take about three hours, will happen overnight, and not affect Valley Line operations.
