^^ they're gonna have to close Stony pain Road over Groat for at least a year or two to replace the bridge, as the new road and rail will follow a more gentle curve, moving the bridge to the south. They patched that Groat Bridge together a few years ago, prior to the 102 Ave bridge replacement to limp it along to it's own replacement for the LRT. also, that bridge is nasty.
It'll be interesting to see how they choose to stage/plan/complete construction. I think the SE section proved that keeping roads open at all times during construction isn't worth it in some areas, and the ripping-off-the-band-aid approach of closing a road completely for a season to get work done faster can be better. Like I said above, it's been done before on Stony Plain Road; in fact, 107 Ave has been seeing paving work this summer in anticipation of more traffic. I think closing Stony from 124 to 102 ave is pretty much inevitable. not as familiar with further out west though; I could see closing the area of 156 around Meadowlark Mall completely given it's relatively low-traffic. idk. We'll find out in a few months when they announce the contractor!
