Private or Public Road Bexar County

[Mike T.]

I am looking at a 2 acre property in Bexar County Texas.  It is located on a small dirt road with about 12 houses.  My title report states that access is not guaranteed.  How can I verify access.  The plat map recorded with county in 1963 shows the road.  The title company says to get a survey and then submit it to them.  But I do not want to spend additional money on a property I cannot purchase, any ideas.

Thanks

Mike
