Boulevard (usually called "The Boulevard," sometimes called the "Kenilworth Boulevard") forms the principal thoroughfare through Kenilworth, extending from Galloping Hill Road in Union to Springfield Avenue in Cranford. Its unusually generous width reflects the original planning ambitions of the New Orange Industrial Association.
At milepost 1.67, the Rahway Valley Railroad’s mainline crossed the Boulevard at grade. Sometime between 1910 and 1919, a second track was laid across the roadway to serve the factories lining Market Street. By 1944, the crossing consisted of two tracks—the main and a siding—set in a plank surface across a macadam roadway. Vehicular traffic was described as heavy, and the crossing was protected by a pair of standard wooden Public Utilities warning signs.
The crossing endured largely unchanged for decades. In August 1988, Delaware Otsego Corporation rebuilt the grade crossing, removing the siding from the roadway in the process. The remaining track survived for nearly three more decades, until it too was lifted from the Boulevard in December 2016.
