The Tredway Trail follows the east bank of the Allegheny River for about five miles through Allegheny Township in the northwest corner of Westmoreland County. It runs on the old Allegheny Valley Railroad grade from the Braeburn section of Lower Burrell north past the River Forest golf course and under the Freeport Bridge to Kiski Junction, where the Kiskiminetas River meets the Allegheny. The surface is crushed limestone, resurfaced end to end in 2023, and the grade is rail flat the whole way. The southern miles run through a wooded corridor between the river and a tall cliff. North of the golf course, homes and river landings open up the view.

The Allegheny Valley Railroad laid its first rails up this bank of the Allegheny River in 1855. The line ran 29 miles from Pittsburgh to the Kiskiminetas River that October and reached Kittanning in January 1856. By 1868 it stretched 132 miles to Oil City. The Pennsylvania Railroad leased the road in 1900 and merged it in 1910, and it became the Pennsy's Allegheny Branch. Where the branch met the Conemaugh Line at the mouth of the Kiski, the railroad named the spot Kiski Junction. A 726 foot bridge, built in 1899, carried the tracks across the Kiskiminetas there. On May 14, 1984, Conrail abandoned the ten miles between Arnold and Kiskiminetas Junction, and the grade through Allegheny Township went quiet. From 1995 the Kiski Junction Railroad hauled coal and mill freight and ran tourist trains over the old bridge until service stopped after 2016. Allegheny Township began building the trail about a dozen years before 2023. The first two miles from Braeburn to Garvers Ferry Road were paid for by a gift from Clara and Wynn Tredway, and the trail took their names. The township pushed the trail past the River Forest golf course to the Freeport Bridge in 2021. In 2023 a $1.2 million extension, funded mostly by Pennsylvania DCNR and PennDOT, carried it nearly two more miles to Kiski Junction. Armstrong County bought the Kiski Junction Railroad in 2022, so the bridge can become the link to the Armstrong Trail.
