Which directions can't Mianyang Science and Technology Commission overpass take?

Adjustment of traffic measures for the construction of Sanhui Bridge ① From 7: 30 am to 8: 00 pm, it is forbidden to turn left around the Science and Technology Commission Bridge, and social vehicles are allowed to turn left at other times. ② From 7: 30 a.m. to 8:00 p.m., Lisan Bridge is forbidden to go under the tunnel, and social vehicles are allowed to pass through the tunnel at other times. I suggest that you follow the principle of "choose Binhe North Road to bypass in the east-west direction, and choose First Ring Road or Binjiang West Road to bypass in the north-south direction" and try to avoid the two blocking points of Jinzhuyuan and Science and Technology Commission Bridge.
