Can we draw the following hypothesis from the context?

Context:

New York State Route146A (NY146A) is a state highway in New York State. It begins at NY146 in Clifton Park and ends at NY50 in Ballston Lake. It is located entirely within Saratoga County. Route146A is the last existing spur of NY146 in Saratoga and Schenectady counties.

Hypothesis: It begins at NY 146 in Clifton Park next to the playground and ends at NY 50 in Ballston Lake.
It's impossible to say
