text_A: The Highways Agency, in collaboration with BAA, also proposed complementary plans for the Stansted Airport expansion project with regards to access from the M11, and one of these plans (shown above under "Junctions 6-8") was ruled to be unnecessary, while the other plan, which includes spur road and junction additions, is awaiting government approval, which may be granted if the airport itself is expanded.
text_B: If the airport expansion were to take place, does it sound like the government is expecting more traffic congestion on the M11 highway, rather than mostly just on the smaller surface roads?
NO.
