We have issues with freights blocking the major, one-way, east/west corridors in Kalamazoo. Michigan Ave is four lanes heading east, and Kalamazoo Ave is four lanes heading west, so you can imagine the snarl.
When the train is simply passing through, the wait isn't bad, but the trains sometimes perform switching maneuvers that block the corridors for anywhere from 15 minutes to an hour. To add insult to injury, the trains often come through during rush hour. (There is one that often stops me if I leave the house at 7:30 instead of 7:15.)
In 2019, the city came up with a solution that cost much less money than restructuring all of the crossings. When the crossing lights are activated, there are signs far in advance that start blinking and advise you to use the detour. They are highly visible, long before you even get close to them, which gives you time to prepare to use the alternate route. For those unfamiliar with the alternate route, orange detour signs are posted to help you follow it.
