[1] Known as Spring Garden Road, it proceeds north-northeast through wooded residential areas.

[1][2] The route crosses Conrail Shared Assets Operations' Beesleys Point Secondary railroad line before intersecting Woodland Drive.

Following this intersection, it passes between several small sized lakes within heavily forested areas before heading through some farm fields.

A short distance later, Route 143 crosses US 30 and continues for a little bit to the end of state maintenance.

[1] The earliest possible evidence of state maintenance of Spring Garden Road came in 1955, when a portion of highway called Route 43 was contracted to be rebuilt north of a crossing with the Pennsylvania Railroad as Section 11E of the highway.
