Amtrak/Pennsy Bridge over Susquehanna River at Perryville, MD

(Bridge Hunter, no Historic Bridges, Satellite, Birds-Eye View)

The motivation for this posting is a long exposure photo so that the passage of an Amtrak train left a streak of light on the bridge by Marc Glucksman.

An Amtrak Acela train set crosses the 1906 vintage, (PRR) Susquehanna River Bridge between Havre de Grace, MD, on the south, and Perryville, MD, north side. Speed limit on the 1453 foot bridge is 90mph passenger, 30mph freight. Weekdays see close to 100 movements with Amtrak, MARC, and Norfolk Southern freight over a 24 hour period. Weekends are traditionally slow with mostly the long distance trains plying the rails here. Photo 3/5/17.
Update: MDOT received $22 million for preliminary engineering and an environmental impact study  to replace the 111-year old (1906), two-track bridge with a high-level, four-track bridge. The finding was "no impact."  [Amtrak]  The replacement would take 10 years and $1.1 billion. [BaltimoreSun-billion]

(new window)  Hopefully passenger trains can go a lot faster over that bridge!

A video (source)  The bridge has just twelve openings a year. $1.7 billion is needed.
