Project: I-476 Blue Route
Summary
Motivation for the I-476 Blue Route highway centered around providing a beltway around the Philadelphia region and relieving traffic on local roads and state highways west of the city. Due to a challenge based on environmental impacts that delayed construction of portions of the highway, the Blue Route was constructed in pieces between 1979 and 1992.
