Eastern Portal
Folks riding buses down the Transitway at the University of Ottawa have likely already been impacted by the slight detour around the Eastern Portal of the tunnel, which is right beside the U of O's Arts Building. So far, it looks like there's just a big hole that's allowing the crew to access utilities, like sewer lines.
Western Portal
A bit more has happened at the Western Portal, which is close to Lebreton Station and right beside the Albert-Transitway Station. A couple of dozen piles have been driven into the ground along the sides of the future tunnel to support it during the descent underground. The piles also show the route that the tunnel will take: It meets the Transitway at the unused portion of Wellington Street and begins its downward slope at Brickhill Street, with the tunnel itself angling towards Queen Street. This map might make that description a bit clearer (click to enlarge)...
Here's a photo of the piles, indicating the pathway the tunnel will take, along with a closeup of a pile into the asphalt of Wellington Street...
Finally, while at the Western Portal I met another Ottawan who was interested in documenting the progress of the LRT contruction--and who'd taken a few photos of earlier progress. Courtesy of Jim Louter (thanks, Jim!), here's a comparative photo of the same stretch of Wellington as the piles were being driven, back on July 11:
And here's a photo of what appears to be the archway that'll mark the top of the tunnel entrance, taken yesterday (July 30), again courtesy of Jim Louter:
That's all I've got for today, but I'll try to have periodical updates with photos to show how the project is progressing (although it might be more difficult, as it appears the crew is putting in permanent fencing around a larger area of the site). If you've got photos you'd like to share, feel free to e-mail me (make sure to include the dates they were taken!) and I'll try to include them in future updates!
