context_page_description: Pennsylvania Route 423 is a state route in Monroe and Wayne Counties in Pennsylvania. It runs for 14.32 miles, crossing through the Pocono Mountains from PA 940 in Pocono Pines to PA 191 in South Sterling. The route runs southwest-northeast through forested areas of the Pocono Mountains as a two-lane undivided road. In Tobyhanna, PA 423 has an interchange with Interstate 380 and an intersection with PA 611. Farther northeast, the route crosses PA 196 in Gouldsboro. PA 490 was designated in 1928 to run from U.S. Route 611 in Tobyhanna northeast to PA 90 in Laanna. In the 1930s, the route was extended and realigned to run from PA 940 in Pocono Pines to PA 90 in South Sterling. PA 490 became PA 423 in the 1960s.
context_section_description: PA 423 begins at an intersection with PA 940 in the community of Pocono Pines. The route heads northbound as Warnertown Road, progressing around the shores of Lake Naomi. The surroundings of the highway are primarily residential. Just after the intersection with Firehouse Road in Pocono Pines, the road turns eastward along the westernmost shore of Lake Naomi. After PA 423 leaves the shoreline, it turns northward and continues through the residential hills north of the lake. The highway passes through a small community named Lake Naomi Estates. It soon passes a local school and leaves Lake Naomi Estates. The surroundings become woodlands as PA 423 darts northwest and soon to the northeast. The two-lane highway maintains the northeast progression through forests until turning north and crossing a creek. There it turns eastward and returns northeastward for several miles and after several changes enters the community of Warnertown. Just after crossing the small community, PA 423 enters an interchange with I-380.
  After crossing the interchange with I-380, PA 423 heads eastward and enters an at-grade intersection with PA 611 in Tobyhanna. The road is renamed to Prospect Street and enters downtown Tobyhanna, crossing through a residential stretch. At Main Street, Prospect Street ends and PA 423 turns northward onto Main Street. This does not last, as the designation darts northward on Church Street. Following Church Street out of downtown Tobyhanna, PA 423 crosses the Delaware–Lackawanna Railroad, passing the former Tobyhanna Station and interlocking tower for the switch to the Tobyhanna Army Depot. The highway continues north of the tracks and along the side of the Army Depot into a rural portion of Tobyhanna. The name changes from Church Street to Tobyhanna State Park Road, entering the namesake park near Tobyhanna Lake. PA 423 passes the dam attached at the end of the lake, and crosses along the side of the park. After passing the state campground entrance, the highway heads eastward through a stretch of woodlands, crossing and passing two routes of power lines. After passing to the north of a large residential complex, the highway intersects with PA 196 in Gouldsboro.
  After crossing PA 196, PA 423 changes names to Carlton Road and parallels PA 196 northbound along Kistler Ledge. After the two roads fork in different directions, PA 423 crosses the county line into Wayne County. The route passes a few stretches of residential homes and much woodland in Wayne County, turning to the northeast and intersecting with PA 191 in the community of South Sterling. This also serves as PA 423's northern terminus, as the right-of-way merges into PA 191.
