Extract polylines from .sid file

Hi all,

I am trying to extract historical road maps from a .sid file. The roads are the only thing colored red on the image so is there a way for me to extract only these red values as a polyline feature? Ultimately, I would like to perform Near analysis using the extracted feature class and some points data.

Much thanks!!
