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 has been deemed unnecessary, Junctions 6–8, see above and the other of which, including spur road and junction additions may be approved by the government if Stansted expansion takes place.
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.
