Can one walk across the border between Singapore and Malaysia via the Johor–Singapore Causeway (Google Maps) at any time in the day/night?
I can't find much information about crossing by foot and opening hours. I know it's allowed in the day, but I don't know whether they close that option at night. There is a second land crossing between Singapore and Malaysia, namely the Malaysia–Singapore Second Link (Google Maps), but it's not allowed to walk across it.
