from Fairview Rd (5.5 miles south of 465) south to Btown, 37 is exactly as it was 20 yrs ago, other than 1 extra stoplight in Martinsville where Walmart is.
in fact, other than the 1 extra light i mentioned in Martinsville, it's the same as it was 30 yrs ago.
from 465 to Fairview Rd though, several lights have been added..
