Reading what xunmeng posted, I believe the accident happened at
the junction just outside the condo, The Florida. If you're talking
about the buses being unable to make a right, i believe it's in the
direction towards Hougang Ave 7. If so, it means that 112 will only
operate 2 busstops before being stuck.
So, shortworking 112 will not work and the buses will not be
able to u-turn back to continue opposite and thus needing to make a
left to Hougang Ave 8 and back to the interchange passing Hougang
Mall.
