State Route 1005 is a short, 3.3-mile-long (5.3 km) road located in Delaware County in Pennsylvania.

In 1987, a Location Referencing System (LRS) was established to define roadways that the Pennsylvania Department of Transportation deemed important.

The system added the concept of a quadrant route, a road given a uniform four digit number between 1000 and 4000 that was unique per county.

Quadrant routes would only be signed in little white markers placed at major intersections.

[2] With the creation of the LRS; Drexel Avenue, Eagle Road, and Wynnewood Road were assigned the number of 1005.
