Woodbridge Cloverleaf

Woodbridge Cloverleaf, Viewed from overhead or on maps, the “cloverleaf interchange” resembles the leaves of a four-leaf clover and was designed in the early days of motoring to keep traffic flowing smoothly through an intersection without use of traffic signals. The cloverleaf interchange was patented in the United States by Arthur Hale, a civil engineer in Maryland, on February 29, 1916., The first cloverleaf interchange built in the U.S. was the Woodbridge Cloverleaf opened in 1929 at Route 25 and Route 4 (now Route 1/9 and Route 35). Modeled after a plan from Buenos Aires, Argentina, the Woodbridge Cloverleaf was designed by Rudolph and Delano engineers of Philadelphia. Listed on the National Register of Historic Places, the Woodbridge Cloverleaf was lauded as “an outstanding development” in traffic engineering by the Engineering News-Record, which in the same 1931 issue relegated the upcoming Hoover Dam to its back pages., As traffic volumes increased in succeeding years, the original cloverleaf design became obsolete; in 2006, New Jersey Dept. of Transportation demolished the Woodbridge Cloverleaf and began construction on a modified partial cloverleaf interchange at the same location. A documentary film by Sica productions, The Woodbridge Cloverleaf: On-ramps to Innovation, details the structure’s history., More information visit www.wthpc.org , Woodbridge Township Historic Preservation Commission , Mayor John E.
