Historic Bridges: Keysville - Four Points

I thoroughly enjoyed RuneE's meme Bridges Between. The meme included the widest definition of the title, with posts on ways of connecting people other than the traditional structure crossing some chasm. I am going to post here a personal theme "Historic Bridges" focusing on bridges in our area that have historical significance. Frederick County has 29 such bridges with spans over 20 feet. There are also other bridges in Maryland that I want to cover. Most of the Frederick County historic bridges were built in the late 1800's or early 1900's. Three are wooden covered bridges; one is a stone arch bridge; and 25 are metal truss bridges. In 1990 the county Department of Highways and Transportation began a program to rehabilitate and preserve these bridges. Some were rehabilited by county crews and contractors were hired for others. The county is planning to keep these bridges open as long as the traffic load does not exceed bridge capacity.

These historic bridges were posted as part of Bridges Between:


Roddy Road Covered Bridge posted April 2008
Legore Stone Arch Bridge posted July 2008
Antietam Lower Bridge (aka Burnside's Bridge) posted August 2008
Utica Mills Covered Bridge posted September 2008
Stevens Road Bridge posted December 2008
Bullfrog Road Bridge posted January 2009
Sixes Road Bridge posted February 2009
Bennies Hill Road posted March 2009

In addition, Marianne posted Loy's Station Covered Bridge in September 2007. All are in Frederick County except Antietam Lower Bridge, which is in Washington County on the site of a major Civil War battle.

Today's post is the Keysville - Four Points Bridge spanning Tom's Creek in the northern part of Frederick County. This is a Pratt truss bridge. It was built by the Wrought Iron Bridge Company of Canton, Ohio in 1880. It was washed off its abutments by Hurricane Fran in September 1996, lifted out of the creek by a crane, rehabilitated and placed back on its abutments. It reopened to traffic in August 1997. In addition to being a county historic bridge, it is listed in the National Registry of Historic Places.
