Unused county road on my property land, what to do?

[Jesus Sosa]

I was door-knocking yesterday to get a feel of the neighborhood I am planning to invest in. The next-door neighbor gave me lots of details of the area and even told me about a road that was once used for traffic bypass back in the 1980s. This road happened to be in between his house and mine, and it runs through my back yard and onto the main road. He mentioned, the county just didn't seem to care and let the woods grow overtime. Now, since this area isn't used anymore could I contact the county to either clear out the road again or sell it to me? I know this may seem confusing, but below will be a picture of what it looks like in the tax map. What should I do with the "potential" additional land?

I am sure this is state specific..  I was building a 120 unit development on the Oregon coast and there was an old road on the plat.. it was one of those roads out west that is platted but could not way be built Striaght up and down.. we were able to ablandon it and buy it.. But every lot that had access to that road had to sign off .. about 15 property owners.. city was fine.. just needed to clean  up the title like Tom mentioned
