I don't think so, maybe for Persiaran APEC yes, but for GR can have alternative road using LDP which is parallel and just beside only. LDP has 3 or 4 lanes, don't think will get jam. So, if you are staying near MMU area and if you are coming from Puchong or Dengkil direction, then you might get caught with the traffic or at least have to pass through a few traffic lights. But if you are staying in GR, directly can reach home without any traffic light via LDP. MEX2 extension coming soon too. What do you think?
