Does anyone know the mean Bedrock depth in downtown Hfx? Would it be possible to create shallow cut-and-cover tunnels in some places such as Barrington? There are a few underground walkways downtown, so it might not be out of the realm of possibility.
And I definitely wouldn't be against taking a cautious look at an elevated line. Most of the peninsula is composed of houses that are fairly close to the street but has a fair amount of land behind them, which could be a good passage way for an LRT. Although I admit, this might stir the NIMBYs into quite the frenzy.
