2nd Gen Underground Paths

[Chrono Cr@cker]

I desperately need this information for my hack. I do hope someone will be able to help me.

In Pokemon G/S, there are 2 underground paths, one is in Goldenrod City, the other links between 2 routes. I want to know which 2, can someone tell me?

Thanks for your help.

The one below Cerulean and above Vermilion.

 

[The Fallen]

Yes, one that leads from Ceurlean to Vermillion.I'll leave this open for you to ask more if you need to.

Thank you cm and DSS, can someone give me the exact route number.
I forgot to save my G/S Game after I finished it.
