Rt. 57 Lopatcong Creek Culvert Replacement

TYLin International served as the prime consultant for NJDOT, overseeing Preliminary Engineering, Final Design, and Construction Engineering for the replacement of the Rt. 57 culvert over Lopatcong Creek. The original 1921 structure—a single-barrel, four-sided reinforced concrete box culvert—was functionally obsolete and in need of replacement. Given its location near the intersection of Rt. 22 and Phillipsburg’s population center, the route sees over 11,000 vehicles daily, making uninterrupted traffic flow and schedule efficiency essential.
