The congestion has been caused by increasing vehicles travelling through the tunnel. In the morning, there is a large volume of automobiles cut off motobike lane to turn left into Pho Duc Chinh street in District 1 side. In the afternoon, motorbikes travel slowly when approaching the stop light in District 2.
Travel has been difficult and dangerous in the tunnel because of sloppy road and poor light. Many drivers enter other lanes regardless of one way streets to escape from the traffic jam, causing chaos in front of tunnels.
SGGP readers say it is needed to study more suitable traffic segeration measures to ensure convenient and safe travel through the tunnel.
