Interchanges 1 to 4 Capacity Enhancements

Salem, Gloucester, Camden, and Burlington Counties

Description

A third lane will be added in each direction over the southern 36.5 miles of the Turnpike. This is the only section of the roadway where the capacity remains at the original two lanes northbound and two lanes southbound. The Program includes improvements at Interchanges 1, 2, 3, and 4 and the replacement or rehabilitation of 56 of the 66 bridges over or along the Turnpike. Environmental benefits include the incorporation of green infrastructure elements to improve water quality, and planning for both the current and future needs of electric and autonomous vehicles.

Schedule

Preliminary design and environmental studies are complete. Final design, engineering, and environmental permitting are underway. Construction is expected to begin in 2026.
