Conshohocken is a town and borough on the Schuylkill River inMontgomery County, Pennsylvania, in suburban Philadelphia. Historically a large mill town and industrial and manufacturing center, after the decline of industry in recent years Conshohocken has developed into a center of riverfront commercial and residential development.According to the United States Census Bureau, the borough has a total area of 1.0 square mile (2.6 km2), of which, 1.0 square mile (2.6 km2) of it is land and 0.04 square miles (0.10 km2) of it (2.97%) is water.Conshohocken fronts the Schuylkill River. A rather sharp bend in the river at Conshohocken gives the Schuylkill Expressway, which hugs the far bank, a curve that is well known to regional radio listeners as the Conshohocken curve (it is a staple of traffic reports). Railroad tracks line both river banks, reflecting the valley's heavy industrial past as well as its continuing rail activity including CSX and SEPTA. A rail trail portion of the Schuylkill River Trailalso passes through.
