The Leechburg Bridge is a bridge that crosses the Kiskiminetas Riverbetween West Leechburg and Leechburg in Pennsylvania U.S.A. It carries unsigned state route 4093 and connects with Pennsylvania Route 66 just after the Leechburg approach.
This five-span 1935 truss bridge replaced an older structure on the site. It features unusually wide shoulders, due to the presence of turning lanes immediately at the ends of the bridge. In 1984, the bridge was rehabilitated.
