Alongside an industrial area off Route 412, an Interstate 78 overpass carries tractor-trailers Wednesday, July 23, 2025, beyond an unimproved section just south of the South Bethlehem Greenway. Construction is scheduled for 2026 to complete the trail atop former railroad bed and connect to the Saucon Rail Trail.Kurt Bresswein | For lehighvalleylive.com
Trees offered shade from the July sun Wednesday along an old railroad bed where the South Bethlehem Greenway turns to rock-strewn weeds.
About a mile south, beyond the hum of the Interstate 78 overpass, the 7.5-mile Saucon Rail Trail awaited to take bicyclists, joggers and walkers from Hellertown through Lower Saucon Township to Coopersburg, and the 3.2-mile Upper Bucks Rail Trail still further south.
