"征收通行税的关卡" can be translated into English as "a toll collection checkpoint" or "a toll gate" (depending on the context, with "toll gate" being more commonly used in everyday language for the physical structure where tolls are collected).
"Toll collection checkpoint" emphasizes the function of collecting tolls.
"Toll gate" is more straightforward and refers to the specific location or structure where the toll is paid.
Both are acceptable, but "toll gate" is likely to be more immediately recognizable in common usage.
