text_A: By way of complementary plans for proposed expansion of Stansted Airport, the Highways Agency collaborated with BAA on improvements to transport access to the airport including two proposals for the M11, one of which--see Junctions 6–8 above--may be approved by the government if Stansted expansion takes place, while the other, which included spur road and junction additions, was deemed unnecessary.
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?
YES.
