Pennsylvania Route 291 over the George C. Platt Bridge

George C. Platt Bridge is an 8,780-foot-long cantilever through truss span located in the city of Philadelphia. The George C. Platt Bridge carries Pennsylvania Route 291 via Penrose Avenue over the Schuylkill River east of Interstate 95 towards Interstate 76. The George C. Platt Bridge opened during 1951 and was a replacement for the earlier Penrose Ferry Bridge.

Part 1; the history of the George C. Platt Bridge

Prior to the construction of George C. Platt Bridge traffic over the Schuylkill River was carried by way of the last generation Penrose Ferry Bridge. The last Penrose Ferry Bridge initially was completed over the Schuylkill River by 1878 and featured an iron swing span design. The iron swing span of the Penrose Ferry Bridge can be seen during 1880 in a Philadelphia Department of Records photo (courtesy Philadelphia.blogspot.com).

The iron swing span of the Penrose Ferry Bridge was replaced by a steel swing span during 1900. The steel swing span of Penrose Ferry Bridge can be seen below in a Philadelphia Department of Records photo (courtesy bridgerhunter.com) dated to 1910.

The original iteration of Pennsylvania Route 191 was aligned over the Penrose Ferry Bridge by 1928. Pennsylvania Route 191 was aligned between US Route 1/Baltimore Pike and Broad Street in downtown Philadelphia via Penrose Avenue. The Penrose Ferry Bridge would remain in service until March 29, 1947, when it was struck by a container ship. Pennsylvania Route 191 and the Penrose Ferry Bridge can be seen below on the 1948 Rand McNally Map of Philadelphia.

The damage to the Penrose Ferry Bridge necessitated it be replaced by a modernized span. The Penrose Avenue Bridge would open on September 12, 1951, as part of an extended Pennsylvania Route 291. The Penrose Avenue Bridge was a fixed 8,780-foot-long cantilever through truss span which provided more utility than the previous swing span of the Penrose Ferry Bridge. The Penrose Ferry Bridge can be seen carrying Pennsylvania Route 291 over the Schuylkill River on the 1956 Gousha Map of Philadelphia.

A steel divider was installed on the Penrose Avenue during 1967 to mitigate head on collisions. The Penrose Avenue Bridge was renamed in honor of Civil War figure George Crawford Platt during 1979. During 1984 and 2011-2014 the George C. Platt Bridge was rehabilitated. Below the fixed span of the George C. Platt Bridge can be seen a D. Thomsen photo (courtesy bridgehunter.org).

Part 2; a drive on the George C. Platt Bridge

The below sequence of photos was taken by Tom Fearer during the 2022 Philadelphia, PA National Road Meet along the George C. Platt Bridge. Below Pennsylvania Route 291 can be seen crossing the George C. Platt Bridge east from Interstate 95 over the Schuylkill River towards Interstate 76.

Paper Highways: The Unbuilt New Orleans Bypass (Proposed I-410)

There are many examples around the United States of proposed freeway corridors in urban areas that never saw the light of day for one reason or another. They all fall somewhere in between the little-known and the infamous and from the mundane to the spectacular. One of the more obscure and interesting examples of such a project is the short-lived idea to construct a southern beltway for the New Orleans metropolitan area in the 1960s and 70s. Greater New Orleans and its surrounding area grew rapidly in the years after World War II, as suburban sprawl encroached on the historically rural downriver parishes around the city. In response to the development of the region’s Westbank and the emergence of communities in St. Charles and St. John the Baptist Parishes as viable suburban communities during this period, regional planners began to consider concepts for new infrastructure projects to serve this growing population. The idea for a circular freeway around the southern perimeter of t

Huey P. Long Bridge (New Orleans, LA)

Located on the lower Mississippi River a few miles west of New Orleans, the Huey P. Long Bridge is an enormous steel truss bridge that carries both road and rail traffic on an old-time structure that is a fascinating example of a bridge that has evolved in recent years to meet the traffic and safety demands of modern times. While officially located in suburban Jefferson Parish near the unincorporated community of Bridge City, this bridge’s location is most often associated with New Orleans, given that it’s the largest and most recognizable incorporated population center in the nearby vicinity. For this reason, this blog article considers the bridge’s location to be in New Orleans, even though this isn’t 100% geographically correct. Completed in 1935 as the first bridge across the Mississippi River in Louisiana and the first to be built in the New Orleans area, this bridge is one of two bridges on the Mississippi named for Huey P. Long, a Louisiana politician who served as the 40th Gove

Legacy of US Route 466 Part 5: Old Highway 58 through North Barstow

Old Highway 58 is a relinquished portion of what was once US Route 466 in the North Barstow area. US Route 466 served the North Barstow area from 1933 until it was truncated to Baker during June 1964. The segment would become the easternmost portion of California State Route 58 which remained as an active highway until 1996 when freeway south of downtown Barstow opened. Old Highway 58 has numerous remaining Caltrans signs and more or less functions as an alternative northern bypass of downtown Barstow. US Route 466 can be seen branching from US Route 91 in North Barstow on the 1953 United States Geological Survey Map.
