With repairs planned for Cobb Street bridge, Lula is turning its attention to another, nearby railroad crossing — this one running under Norfolk Southern tracks. Officials are looking at possible improvements to a narrow, graffiti-laden tunnel under tracks on Homer Road, jutting off Main Street in what is a link from one side of town to the other. Hall County Fire Services, along with Hall County officials, “is currently evaluating the turning and size requirements of this intersection as it pertains to public safety operations,” Fire Services spokesman Zachary Brackett said Thursday.
