There has been considerable delays and extended disruptions to local business, residential areas and traffic during the existing Eglinton Crosstown construction project. Will there be any lessons learned to improve this upcoming Eglinton West Crosstown Extension construction process?

Thanks

Is the line being constructed to Pearson Airport in one phase or will the Pearson segment be constructed at a later date as a phase 2?

Will the extension includes a potential direct connection or even interlining with the Jane LRT?

There is no debate about the alignment through Eglinton Flats, as it must be elevated. Even the Scarlet Station must be elevated for hydrology reasons. The line would then go underground several hundred metres West of Scarlet. Due to Mimico Creek, the line will become at-grade or elevated by this point. This leave about 4km, which can easily be built using cut-and-cover. Not only is this less expensive, it is faster to construct, more ability for local contractors to bid on and more convenient for riders when in service. It also make the stations shallower (and faster to construct), which has shown to be a large problem from the Central Eglinton experience. Generally, the excavation would be in the North ROW, avoiding the Gas Line on the south side. Cut-and-cover stations would be at Royal York, Islington, Kipling and Martin Grove. West of Martin Grove, there would be a relocation of the Eglinton/Eglinton intersection (for which there is already a separate study) to West of Mimico Creek, allowing space for the LRT to emerge south of Eglinton, and West of the hydro corridor. With slight re-configuring of the 427 ramps, the LRT could run at-grade under the end spans of the 427 bridges.
About the worst idea for this transit line would be to use TBM tunneling.

There's ample room along the entire street for rail tracks and platforms, and apart from the westernmost part under the 427, even for two extra vehicle lanes on top of that. From Islington eastward, the street is so wide that you could build the LRT in a trench right up to the start of the elevated section.

So why are you planning to tunnel the whole thing? Tunnelled construction costs at least twice as much as surface. What justifies that cost?

How does one make a left turn from Eglinton Ave west to southbound Scarlett rd?

I see absolutely zero wisdom in burrowing an extremely long tunnel in the middle of suburbia when the exact same transit outcomes -- in terms of speed, ridership, automatic train control potential -- can be created for a fraction of the cost by elevating the line the entire way to Renforth. Money is tight now, given these crazy circumstances, so why waste huge sums of taxpayer dollars when we can EASILY avoid it? The Skytrain model works really really well in Vancouver. They'd never have seen the expansion they did if they were committed to costly tunnels 100% of the time.

It seems especially wrong to tunnel here when the much busier Ontario line will likely be elevated through low-income neighbourhoods like Thorncliffe Park -- at the possible expense of a convenient transfer to Line 5 at Don Mills. This whole situation feels so inequitable to me.

Between Martin Grove and Renforth Rd there are a lot of houses that would benefit by an extra stop. My house is at
Courtwright Rd. There was a suggestion of a stop at Rangoon Rd as recently as last year, I believe. What happened to that?
