DE 34 began at an intersection with Duncan Road north of Prices Corner and headed east on two-lane undivided Faulkland Road through wooded areas and homes, crossing Hyde Run. The route intersected DE 41 and passed north of Brandywine Springs Park, where a park and pool lot is located, before it crossed Red Clay Creek and the Wilmington and Western Railroad at-grade. The road continued east through suburban neighborhoods, crossing Centerville Road. Farther east, DE 34 ran through residential and commercial areas, crossing Little Mill Creek before it came to an intersection with DE 141. Past this junction, the route passed to the south of DuPont's Chestnut Run Plaza research facility and headed across Chestnut Run. DE 34 crossed an East Penn Railroad line at-grade and ran between two cemeteries before ending at DE 100 north of the town of Elsmere, just west of the western city limit of Wilmington.
