Keeping up with reroutes

I semi-recently published an unofficial app for the local bus system and only then realized how often there are reroutes. I signed up for reroute notifications about all routes from the official bus company so that I can manually create concise alerts in my app. (Most students aren't aware of the official alert system, and it's nice to have the alert right in a bus app instead of needing to check e-mail or a web site.) A particular, moderately important thoroughfare tends to get closed for large music-related events, including some festival this weekend, which affects a ton of campus routes.
