Clear now thanks for the clarifaction Tom. I'm afraid that it wasn't clear because I neglected to see a correlation between the two questions/answers seeing as they were 2 different projects listed on the CV that I'm translating. The important thing is that I understand now. Your explanation was needed. I appreciate it.

it was clear vivi, it was clear, from your other question, that this refers to the pay toll lanes of an autostrada. These lanes are separated by walls or separators, and the finish to the terminals of these separators is very important because, seen from a distance, the motorist has to be able to decide which lane to enter. I thought that was all perfectly clear anyway.....
