New Jersey Turnpike – Interchange 6 to 9 Widening, Section 1

The Turnpike 6-9 Widening Program is the largest capital expansion program undertaken by the Authority since the construction of the New Jersey Turnpike back in the early 1950s.

This $2.6B widening program provided for the construction of three-lane outer roadways (truck lanes) northbound and southbound from the southerly terminus with Interchange 6- Pearl Harbor Memorial Turnpike Extension (PHMTE) to the northerly terminus tying into the existing ten lane dual-dual mainline in the vicinity of Interchange 9; a distance of approximately 34 miles.

Section 1 of this proposed widening program in the Townships of Springfield and Manchester in Burlington County, New Jersey, is the southerly most section extending from mile post (MP) 48.7 to 52.3; a distance of 3.6 miles. Included within this section is the PHMTE interchange (Interchange 6).

As a major Design Team member, NV5 was responsible for the final design of the section-wide highway, environmental, stormwater management, ITS, and utility engineering components of the Section 1 widening improvements and also provided final design/engineering services for the four local road crossing structures, traffic, ROW, and construction support tasks. We established and coordinated the geometrics for the mainline widening and the local arterial crossing roadways and prepared highway plans and documents for two of the three construction contracts.
