Vancouver 2010 is a
fantastic example of just that. Yes, there were some developments which could have gone better (Olympic Village, for one), but some much needed infrastructure and stadium upgrades came out of it:
- Sea to Sky Highway went from being a ridiculously dangerous road between Vancouver and Whistler to being a pretty good road (still twisty, but there's only so much that can be done about that), and sorely needed these improvements for many, many years without budget for it.
- Canada Line also received a whole bunch of federal money to get built, probably bringing it ahead of schedule by many years. An airport transit line was badly needed in Vancouver, especially with $40 cab rides to downtown.
- BC Place's renovations got a major budget boost from the Olympics, allowing it to be turned into a great venue. The pressurized roof was a huge annoyance (air locks, yay! /s) and collapsed on several occasions, so the new retractable roof probably wouldn't have happened without the Olympic money.
- Cypress Mountain finally got off their ass and built a proper lodge with proper facilities to support the Olympics.
Vancouver also reused a lot of existing stadiums and infrastructure, opting to upgrade rather than build from scratch. It was honestly an example of a really, really well executed Olympics with a lasting legacy. There have been complainers the entire time, but honestly, it made Vancouver a better city. Closing of Granville for theentirety of the games also allowed the city to experiment with closing off city blocks for events, and that now has become a yearly tradition (along with Robson St). On a more sentimental note, it brought the country together in a unified passion which I had not seen before and have not seen since. It was truly a spectacular experience. I like rewatching the closing comments on CTV (https://www.youtube.com/watch?v=vX_dndXEGHI) as well as Stephen Brunt's video essay (https://www.youtube.com/watch?v=kz8tzP3oeDg) every so often to remember that.
