Significance: This viaduct is part of the Route 1 Extension, an early example of planned, limited access, road construction built to carry high speed automobile and heavy commercial traffic. Designed and constructed from 1924 through 1932, it was one of the first highways in the nation and the first in New Jersey to be planned and laid out according to any rational economic process or formulae, and was regarded by engineers of the period as a model in its day.
