Portuguese to English Bus/Financial Transport / Transportation / Shipping

This is European Portuguese, from a presentation on business and industrial parks:

"O Parque Empresarial é assistido pela A1 e pela A29,..."

"Assistido pelas autoestradas A2 e A12, o Parque Industrial fica a..."

"Situado em Almada, assistido pela A2 e pela ligação fluvial Almada-Lisboa,..."

I imagine that "assistido por" should be translated simply as "reached by" or "accessible by", but I want to double check, since I've never seen the verb assistir used in this exact way before.

Thanks in advance for your input.
