North of Allentown, the route runs through more farmland before passing under the Blue Mountain in the Lehigh Tunnel and entering Carbon County in the Pocono Mountains. Here, I-476 crosses over the Lehigh River and comes to an interchange with US 209 near Lehighton. Continuing through mountainous areas, the route has a ramp to the dual-access Hickory Run Service Plaza before it has an E-ZPass-only exit for Pennsylvania Route 903. Past here, the toll road cuts through Hickory Run State Park before reaching an interchange with Interstate 80 and Pennsylvania Route 940 just to the north of the state park. The route continues through mountainous terrain, heading into Luzerne County and coming to an interchange with Pennsylvania Route 115 in Bear Creek that provides access to nearby Wilkes-Barre. The route comes to a toll barrier near Pittston that marks the northern end of the toll ticket system in the Northeast Extension. A short distance later, an interchange with Pennsylvania Route 315 provides indirect access to Interstate 81 and Scranton.
