The highway is accessible for vehicles used by newlyweds and funerals. So I tagged the crossing "uncontrolled".
Besides, I removed the name "Skwer Prymasowski" from the highway. In Polish "skwer" (pronunciation is similar to "square") is used for green areas (not for highways). The resolution of City Council on creating "Skwer Prymasowski" is here (with map): http://edziennik.mazowieckie.pl/WDU_W/2009/221/7009/Akt.pdf
