One thought on “SBS Transit Bus Service 142

  1. They should build a long-like bus stop at the exit of the Potong Pasir MRT station, but it would be considered as a bus interchange

    142 should be ammended to Potong Pasir and the loop towards Punggol will no longer exist. While new bus routes to Yishun, Serangoon, Pasir Ris, Tampines, Changi Airport, Jurong East and Boon Lay
