Vancouver, in 2025, should be home to a new mostly-tunneled Skytrain route through BC’s second-largest jobs centre. It’s rapid transit where it’s definitely needed.
HERE‘s Kenneth Chan at the Daily Hive diving into every armchair engineer’s favourite bare-knuckle debate — tunneled vs. elevated.
His review is based on the Strategic Options Analysis (44-page PDF) from BC’s MoTI. It seems there’s a lot to think about — road space changes, parking reduction (or not), loss of left turn opportunities, local street traffic impact, project cost, property acquisition, ongoing development on the corridor.
An elevated concrete guideway, similar to the Canada Line on No. 3 Road in Richmond, would likely result in lower overall construction costs, but would decimate Broadway’s function as one of the largest east-west road arterial routes in the city.
“Typically, an elevated guideway alignment offers a more economical solution in terms of construction costs, however, impacts of an elevated guideway within a corridor must be considered and weighed against potential construction cost savings when determining an optimal solution,” reads the report.
