The long stone bridge over the Raritan River in Highland Park, New Jersey, has partially been covered with concrete - but not all of it. The stone portion can be seen here, as NJ Transit train 3828 (Trenton NJ to Penn Station, New York NY) speeds over the span as it heads north on the Northeast Corridor. Bombardier-built ALP-46 4614 leads this train on the last day of March 2015.
