Río Allegheny

Oil Region National Heritage Area is a federally designated National Heritage Area in the northwestern portion of the U.S. state of Pennsylvania. The national heritage area commemorates and promotes the region surrounding Edwin Drake's oil well of 1859 near Titusville, which gave rise to the modern oil industry.

Oil Creek is a 46.7-mile (75.2 km) tributary of the Allegheny River in Venango and Crawford counties in the U.S. state of Pennsylvania. It has a drainage area of 319 square miles (830 km2) and joins the Allegheny at Oil City. Attractions along the river include the Drake Well Museum and Oil Creek State Park.

The Veterans Memorial Bridge is a girder bridge connecting the North Side and South Side neighborhoods of Oil City, Pennsylvania. Built in 1990, the bridge was one of several similar structures constructed during a decade that saw major replacements of Upper Allegheny crossings; an original truss bridge on the site dated to the 1910s.

The Oil Creek Library District is an administrative unit designated by the Pennsylvania Office of Commonwealth Libraries and charged with facilitating and enhancing public library service in Clarion, Venango, and Jefferson Counties. The District's offices are currently located at the Oil City Library, a public library serving approximately 11,000 people in the city and surrounding areas.

The Petroleum Street Bridge is a girder bridge connecting the North Side and South Side neighborhoods of Oil City, Pennsylvania and crosses the Allegheny River. The bridge sits just downstream from the confluence of Oil Creek and the Allegheny River. The 1995 structure carries two lanes of U.S. Route 62 and was built during a decade of major refurbishments of Upper Allegheny crossings.
