More parents, teachers and local businesses have joined the fight against controversial plans to scrap school lollipop patrols.
Two crossings in Morland Road and Blackhorse Lane, Woodside, are among those at threat as Croydon Council prepares to cut ten staff.
Campaigners collected signatures outside nearby Woodside Primary School on Monday after launching a petition urging the council to rethink the move, which will save it £60,000.
Emma Philbert, 35, whose daughters Naomi and Ruby attend the school, said: "Parents are furious. Blackhorse Lane is such a dangerous junction and people come racing up to it and don't stop even for the lollipop lady.
"Our lollipop lady earns £350 a month - I think that is money well spent on our children's safety."
Council leader Mike Fisher has denied the cuts, which target roads where zebra crossings are already in place, will put children at risk.
