Delaware State Reference Roads
In addition to the Interstate, U.S. and State Route numbers signed on Delaware highways, many roads in the Diamond State are also numbered within the state reference number system. These designations are often displayed on placards or street signs at an intersection of a local road or neighborhood surface street, where signs display “Road NNN”, where the N’s represent the reference number. Designations are generally used for maintenance purposes by the Delaware Department of Transportation (DelDOT) on internal documents, similar to hidden state route designates in other states. However in rural portions of the state, the reference numbers may act as the default road name as well.
Every segment of the state maintained system is assigned a reference number. Additionally, old segments or spurs/loops of these roads are often signed as a branch reference road with lettered suffixes as well. For example, SR 896 between I-95 and SR 71 is assigned reference number 387. The original SR 896 route through Glasgow (SR 896 Business) is assigned reference number 387A. These numbers can be useful if coincided with a good highway map.
