The Jay Street Bridge crosses the West Branch Susquehanna River between Lock Haven on the south bank and Lockport on the north. The original structure, completed for the Lock Haven Bridge Company by the E. Kirkbride Company in 1852, was a covered bridge about 800 feet (240 m) long. A two-story toll house, 48 feet (15 m) long and 18 feet (5.5 m) wide was later added at the foot of the bridge on the Lock Haven side. Travelers using the bridge passed through an archway in the center of the toll house. The bridge included a covered pedestrian walkway on the downstream side.After the wooden bridge was destroyed by fire in 1919, it was replaced by an iron bridge, and a steel girder bridge replaced the iron bridge in 1986. State Route 664, the southern terminus of which is in Lock Haven, crosses the river over the steel bridge. The bridge is slightly upstream of Lock Haven's Canal Park, featuring remnants of the Bald Eagle Crosscut Canal. It is also slightly upstream of the Lock Haven Dam (also known as the Dunnstown Dam), built in the 19th century to provide water to the West Branch Canal, which ran parallel to the Lockport and Dunnstown side of the river. Canal boats crossed the pool behind the dam by means of a cable ferry between Lock No. 34, about 2,000 feet (610 m) east of the bridge on the Lockport side, and Lock No. 35 on the Lock Haven side.The steel bridge is 8.5 metres (28 ft) wide and about 250.5 metres (822 ft) long. It has an operating rating (maximum allowable weight of a vehicle using the bridge) of 60.8 metric tons (67.0 short tons). In 2007, the average daily traffic count for the bridge was 3,646 vehicles.

The Memorial Park Site (designated 36CN164) is an archaeological site located near the confluence of Bald Eagle Creek and the West Branch Susquehanna River in Lock Haven in the U.S. state of Pennsylvania. Research projects conducted at the site since 1979 have found prehistoric cultural deposits that collectively span 8,000 years.Stratified in age-related sequence, the deposits represent every major prehistoric period from the Middle Archaic to the Late Woodland. The site's dominant component holds the remains of an early Late Woodland (500–1000 CE) village inhabited by people of the Clemson Island culture. The convergent streams and their two valleys made the site readily accessible to pre-Columbian people living in both drainage basins. Among the components of the site are two strata, dating from 5000-6000 and c. 2600 BP respectively. Both components were radiocarbon dated from fragments of Cucurbita pepo, the squash plant; the absence of wild squash plants near the site and its distance from well-documented wild populations is evidence that the gourds were intentionally brought to the location by humans.Memorial Park contains the only area on the West Branch side of the point of land between the river and the creek that has not been disturbed by subsequent development. Alluvial deposits 20 to 28 inches (51 to 71 cm) deep cover the site and have protected it from recent activity on the surface. The Veterans of Foreign Wars acquired the property in the 1920s and used it for a park.Piper Aircraft bought the fields adjacent to the park in the 1960s to use for airport runways and airplane storage. In the 1970s, Conran A. Hay, a consultant, discovered the prehistoric site during an archeological survey conducted for the United States Army Corps of Engineers. Subsequent research sponsored by the Office of State Archeology and the Office of Historic Preservation of the Pennsylvania Historical and Museum Commission in 1980 helped determine the site boundaries.

The Water Street District, a large part of downtown Lock Haven in the U.S. state of Pennsylvania, is a historic district added to the National Register of Historic Places (NRHP) in 1973. The district includes the city's entire central business district as well as many homes and churches constructed in the 19th century, especially during the Victorian era. An inventory of the district in 1973 listed more than 365 historic resources, many of which were associated with wealth created by the lumber industry.A partial list of the historic structures in the district include the L.A. Mackey House (1854), a Federal-Tuscan Transitional dwelling; the David Carskaddon Homestead (1858), in the Italian Villa style; the James White House (1856), a Greek Revival-Tuscan Transitional dwelling; the Winslow-Crawford House (1855), a dwelling in formal Steamboat Gothic style; the Craig-Furst House (1860), in Gothic Revival style; the Clinton County Courthouse (1867), in Italian Villa style; the Jacob Graftius House (1857), in Federal-Tuscan Transitional style, and the W.A. Simpson House (between 1872 and 1880), a three-story brick dwelling covered with wood made to look like dressed stones. At least eight other important historic buildings, the canal lock from which Lock Haven got its name, and the site of Fort Reed, the last of a chain of early forts along the West Branch Susquehanna River, are also within the district.The district is bounded roughly by the river on the north; North Henderson Street on the east; Bellefonte Avenue, Mary's Alley, and the Penn Central Railroad right-of-way on the south, and Sixth Street on the west.The NRHP is the official federal list of properties of architectural, archeological, cultural, or engineering significance in U.S. history. Benefits of listing include qualification for federal historic-preservation planning and, if available, funding, as well as possible tax relief.

Lock Haven is the county seat of Clinton County, in the U.S. state of Pennsylvania. Located near the confluence of the West Branch Susquehanna River and Bald Eagle Creek, it is the principal city of the Lock Haven Micropolitan Statistical Area, itself part of the Williamsport–Lock Haven combined statistical area. At the 2010 census, Lock Haven's population was 9,772. Built on a site long favored by pre-Columbian peoples, Lock Haven began in 1833 as a timber town and a haven for loggers, boatmen, and other travelers on the river or the West Branch Canal. Resource extraction and efficient transportation financed much of the city's growth through the end of the 19th century. In the 20th century, a light-aircraft factory, a college, and a paper mill, along with many smaller enterprises, drove the economy. Frequent floods, especially in 1972, damaged local industry and led to a high rate of unemployment in the 1980s. The city has three sites on the National Register of Historic Places—Memorial Park Site, a significant pre-Columbian archaeological find; Heisey House, a Victorian-era museum; and Water Street District, an area with a mix of 19th- and 20th-century architecture. A levee, completed in 1995, protects the city from further flooding. While industry remains important to the city, about a third of Lock Haven's workforce is employed in education, health care, or social services.

The main line of the Nittany and Bald Eagle Railroad short line runs along the full length of both Bald Eagle creeks. Interstate 80 crosses the creek between Snow Shoe and Bellefonte, and U.S. Route 322 crosses between Port Matilda and State College. Much of the Nittany Valley drains to the creek through water gaps in the Bald Eagle Mountain ridge. Located along the creek in Unionville is the Fisher Farm site, a significant archaeological site.
