There is an existing priority-narrowing feature on Constellation Street outside Adamsdown Primary School near Anderson Fields; this reduces two-way traffic flow down to single file.
Mae rhwystrau culhau'r ffordd bresennol ar Constellation Street y tu allan i Ysgol Gynradd Adamsdown ger Caeau Anderson; mae’r rhain yn lleihau llif y traffig i un lôn.
