If the railroad bridge over Brandywine Avenue feels like a modern-day bottleneck, history shows it has been causing headaches for more than a century.
According to research shared by the Downingtown Area Historical Society, the problem dates back to the early 1900s, when electric trolleys first came to town. In 1902, Downingtown Borough Council granted the West Chester Street Railroad Company permission to lay trolley tracks through the borough — but with one crucial condition: existing street grades could not be altered.
That requirement quickly became an obstacle at the Pennsylvania Railroad bridge over Brandywine Avenue. While trolley cars themselves could barely fit beneath the bridge, there was not enough clearance for the trolley pole and overhead wire, making the bridge the only (and nearly impossible) entry point for the system into Downingtown.
Without borough approval, the trolley company took drastic action. Crews blasted away the solid limestone roadbed beneath the bridge and lowered the roadway and its approaches on both sides. The changes allowed the trolley to pass through, but they also created a serious new problem.
The lowered roadway formed a basin that repeatedly flooded during rainstorms. Although a drain had been installed, historical accounts suggest it was far too small to manage the runoff. Even after the water subsided, thick mud remained, creating miserable conditions for trolleys, wagons, pedestrians and early automobiles. After one storm in 1906, reports estimated nearly two feet of mud covering the tracks, requiring crews to regularly shovel out the area.
Trolley motormen often attempted to push through the muck, sometimes successfully and sometimes not. Several trolley cars derailed beneath the bridge, occasionally taking hours to rerail and further disrupting travel.
The situation also impacted local businesses. Frank Miller, owner of a paper company just south of the bridge, saw flooding back onto his property and shipments delayed due to the impassable conditions. Miller ultimately sued the borough, which then turned around and sued the trolley company in an effort to resolve the ongoing mess.
While records are unclear on the exact solution, the Downingtown Area Historical Society notes that the issue was eventually remedied, possibly through a joint effort between the borough, the trolley company and Miller. One theory suggests a much larger storm sewer was installed to carry runoff from Brandywine Avenue directly to Brandywine Creek.
