The Lancaster chapter of the National Railway Historical Society hosted the dedication of an illustrated historical marker in Christiana, commemorating the last standing arch bridge from one of the country's earliest railroads.

The dedication of the marker, a tribute to the 1830 stone railroad bridge over Pine Creek on Saturday, Sept. 12, 2020, in Christiana. 

The marker explains the historical significance of the bridge. That history includes the Underground Railroad.

The bridge was built for the Philadelphia & Columbia Railroad, which was eventually used to secretly transport formerly enslaved people as part of the Underground Railroad.
