LA Metro Rail opened a new station to the public today, 11/3/24, at Aviation/Century. The C line now turns north just west of the Aviation/LAX stop and continues to Aviation/Century. Meanwhile, most of the former C line west of Aviation/LAX is now designated as part of the K Line. K Line trains travel north from Redondo Beach, and no longer pass through the Aviation/LAX station. Instead, they turn on the wye and continue north to Aviation/Century. A "bus bridge" connects the two isolated K Line segments. The south leg of the wye west of Aviation/LAX will no longer be used by scheduled trains.
