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 critically necessary (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: From the information given above, does it sound like highway and surface road congestion around the airport was generally considered to be sufficient, given the level of traffic in and out of the airport at the time the passage was written?
NO.
