Entrance to the new route is at the Mabprachan Interchange between the Pattaya and Pong toll gates on the M7, some 20 kms south of Laem Chabang port.
Currently the motorway has only one exit point at Maptaphut in Rayong. Two others are expected to open in September. One is at Huay Yai, which will connect the motorway to to Sukhumvit Road opposite Ocean Marina; another is at Khao Chee Chan, which will exit on to the 331 highway.
The toll fees from Bangkok to U Tapao is 130 Baht for cars, 210 Baht for six-wheeled trucks and 305 Baht for larger trucks.
Constructed at a cost of 17 billion Baht, the M7 extension passes through some of the most beautiful countryside in the Eastern region.
Meanwhile, work on the 331 from Chachoengsao to Rayong continues at Bowin with road widening and construction of several flyovers.
