Changes

Take the metro to '''Haram-e-Motahhar''' (Red Line). Walk West around Imam Khomeini tomb, and South along the Freeway. After 15 minutes, you'll see the pay-toll.

''Redjo27 (Apr 2015): Maybe I was just stupid, but you should walk EAST around the tomb (don't enter), since the western way is blocked. At the northernmost point, there is a street going under the highway. Just follow that street until you get to the toll station. You cannot miss it''
