Work on 35 bridges also involved several improvements: widening along a twelve mile stretch, new bridges, a carpool (HOV) lane, adding shoulders, retaining walls, and a center median stretching from Route 405 to Route 55.

This project utilized a design-build method - a single contract awarded for both design and construction, allowing construction to begin before the design was fully complete. In turn, the project completion date was reduced almost three years.
