The Old Road here was a four lane divided highway. This section of highway was completed in 1930 as a three-lane road and was widened to a four lane expressway in 1951. The expressway was originally paved with concrete but it was paved over in 1994 when this section of highway was used as a temporary freeway during the reconstruction of I-5.
