Chester County is moving ahead with a major overhaul of the Downingtown Trestle Bridge, aiming to fold the century-old span into an extended Chester Valley Trail after years of sitting idle above the valley. County officials say detailed safety inspections are slated for the coming months, to be followed by design work and a multi-year rehabilitation. The steel viaduct, long closed to rail traffic, rises roughly 130 feet over the East Branch Brandywine Creek and stretches about 1,450 feet across the valley.
Calling the trestle the centerpiece of the effort, George Martynick, director of the county's facilities and parks department, told The Philadelphia Inquirer that the bridge is 'a really key part of it' and 'the keystone of the project.' County officials told the paper that inspections will come first, then formal design work, and that rehabilitation of the bridge and the trail extension could take five to seven years. Before the county took ownership of the structure last year, it completed a drone inspection to get a closer look at the aging steel.
Design and funding
To get direct control over the future of the span, Chester County purchased the trestle from PennDOT for $1 last year, giving local leaders the final say on design and safety decisions. The county has since lined up state and regional backing for engineering work. Officials say that state DCNR awards, once matched with local funds and other grants, bring roughly $2.2 million to cover design costs. Materials from the Chester County Planning Commission describe the DVRPC and DCNR awards that will support next-stage engineering.
History and public safety
The Brandywine Valley Viaduct that locals now call the Downingtown Trestle was built in 1903-1904 for the Pennsylvania Railroad, and its tracks were removed in the late 1980s, according to documentation from the Library of Congress. In more recent years, PennDOT has tried to keep people off and debris off the roadway below by installing protective netting under the span and adding higher fencing at likely access points. An archived PennDOT notice posted by East Caln Township outlines work to remove and replace that netting over U.S. 322.
Local reporting and coroner records have documented multiple fatal falls at the structure over the past decade, a grim history that county officials say has to shape any conversion to a public trail. The Library of Congress and East Caln Township provide historical and safety context, while local coverage has tracked the fatalities and community petitions. VISTA Today has reported on recent PennDOT and coroner accounts.
What’s next for the trail
Over the next several months, engineers will use the new inspections to determine whether the structure meets federal standards and what upgrades are needed for it to safely carry a multi-use trail. The Chester County Planning Commission lays out a phased strategy to extend the Chester Valley Trail and lists the Downingtown trestle as a future phase of the P&T extension, making the bridge work central to closing a long-standing gap in the county's trail network.
County planners say residents should expect a staged design and bidding process rather than overnight transformation. They emphasize that the project will move carefully to balance historic preservation of the old railroad span with modern expectations for safety and accessibility.
Local reaction and timeline
Officials and trail advocates describe the project as both historic and complicated, and have warned that patience will be needed as design, permitting, and construction unfold in stages. County commissioners have discussed enclosing portions of the span to prevent trespass and improve safety, and residents who previously pushed for the netting and fencing say they want permanent protective measures built into the final design.
County leaders say they plan to release inspection findings and outline next steps as design contracts are awarded and the multi-year rehabilitation moves forward. MontCo.Today and VISTA Today have been tracking community reaction and safety planning as the project takes shape.
