At the same time, exit 116 for Telegraph Hill Park was being used as an unofficial entrance and exit for Holmdel. The township claimed the Highway Authority, who wanted Red Hill Road improved to facilitate construction of the new interchange, threatened to close it in May 1961. However, the Highway Authority denied this claim from Holmdel, and stated it was too early to know how much the Bell Laboratories facility would add to traffic. Holmdel stated the cheapest method for dealing with traffic to get to Bell Labs was to keep exit 116 open for the traffic to use.
