Okay, so looking into the on-ramp near the tunnel section in SSR7 (entering on the first visit of the tunnel, exiting on the last), it seems that the SSR5 exit onto SSR7 in the first turn has a 50/50 chance of being related to this turn. However, the difference with SSR5 and SSR7 is that 7 is a left hand drive system, while 5 is a right hand drive system. This makes relating the two circuits tricky. SSR11 can be correlated to SSR5 due to the streets being laid as a right hand system, the only thing is we need to know where exactly is it located. @nascarfan1400 can you repost the diagram? It may clear up somethings.
