The road heads northeast through farmland with some woods and homes, passing through the community of Mount Pleasant. Farther along, the route cuts through a corner of Washington Township and runs through the community of Richmond. PA 611 enters Upper Mount Bethel Township and continues through a mix of farm fields and woods with some homes, passing through the community of Centerville. The road continues north through rural land and comes to an intersection with the northern terminus of PA 512 before it heads northeast through the residential community of Mount Bethel. The route runs through wooded areas with some homes and businesses and passes under Norfolk Southern's Portland Secondary, at which point it enters the borough of Portland. PA 611 widens to a four-lane divided highway and splits from the road at an interchange to head northwest on Delaware Avenue, with the divided highway leading to the Portland-Columbia Toll Bridge over the Delaware River to New Jersey, where the road becomes Route 94 and provides access to I-80 and US 46. From here, PA 611 follows two-lane undivided Delaware Avenue through downtown Portland before heading into wooded areas with homes to the southwest and Norfolk Southern's Stroudsburg Secondary and the Delaware River to the northeast. The road gains a second northbound lane and leaves Portland for Upper Mount Bethel Township, heading into forested areas and passing to the west of the community of Slateford. The route heads into the Delaware Water Gap National Recreation Area and narrows to two lanes, passing to the east of Blue Mountain and to the west of a Delaware-Lackawanna Railroad line and the Delaware River as it traverses the Delaware Water Gap.
