Snow, Garbage or Other Sidewalk Obstructions on Shabbos – Halacha

This past Shabbos obstructed sidewalks affected several shul-goers throughout our neighborhoods. Sidewalks which had been cleared before Shabbos had garbage blown onto them or empty garbage pails placed in a way that blocked them by sanitation workers. I personally witnessed someone who walked with a cane being forced to walk over a slippery, snowy area, despite the property owner having shoveled a clear path, due to emptied garbage cans that were placed in a way that blocked the entire sidewalk.
Please be aware that in cases like this moving the obstruction on Shabbos is likely permitted. There are several factors involved in how and if the obstruction should be moved – from reshus harabim to reshus harabim, the distance it may be moved, whether it requires a non-standard method of moving, a clearly dangerous obstruction vs. one that isn’t – and of course nobody should take action based on a post like this one without verifying the halocha for themselves. (I did notice some frum property owners who moved the pails so their sidewalks were no longer blocked, while others did not move them until after Shabbos ended.)
The dinonline website discusses this issue, for those who may be interested.
