Obviously nobody has explained to them that digging up Broadway to put LRT on the surface is equally as disruptive as digging up Broadway to put in a Skytrain tunnel. Whichever type of system you install, you'll be digging up the street to move power conduits, sewer lines, water lines, cable conduits, natural gas lines, Telus conduits (I know I'm forgetting something) so they aren't under the LRT tracks or in the way of the Skytrain tunnels.
Thats before any track construction happens.
If you're building surface LRT, the street gets dug to a depth of around 10 feet to build the required structure for the tracks and signalling system. If you're building Skytrain tunnels, you're now digging down 30, 40, 50 feet or more to build the tunnel and then covering it up again (a la Cambie). In either case, you have months of construction equipment and supplies on the street and sidewalk, no on-street parking, and no stopping in construction zones (other than the buses which will still be running).
Since the street is being torn up, you will get the "While we're doing this, can we also ...." suggestions:
a) add /remove /relocate the trees
b) add/ remove street parking
c) add /remove /relocate bus stops
d) add /remove /relocate truck loading zones
e) widen / narrow / straighten / level out the sidewalks
f) add /remove /relocate pedestrian crossings
g) add /remove traffic lights and/or left-turn lanes
h) add /remove /relocate the rush-hour Diamond Lanes
I) add /remove /relocate Bike Lanes
which add to the cost & add extra time to finish the project.
(all 77 blocks of it)
Look how long it took to re-surface 10 blocks of Granville street. This didn't require major moves of power conduits, sewer lines, water lines, cable conduits, natural gas lines &tc. to make way for LRT tracks on Granville either. Just new sidewalks, curbs and asphalt. And some granite accents and fancy lighting. The new trolley wires are still being installed, but the trolleys won't be back on Granville until September (I think)
