Boston roads were fine until, boom, they weren't

3 p.m., more or less, is when roads all over the city went to hell - especially the ones with hills. Washington Street from Roslindale Square to the Dedham line became a skating rink. A bus slid into a car at Beechland Street.

Columbus Avenue from Egleston Square north turned similarly impenetrable. A salt truck got stuck at Bragdon - its supply of salt gone.
