These are notes that I am writing to help me learn our industrial history. They are my best understanding, but that does not mean they are a correct understanding.

| Michael Cheek posted The Guilford Quarry Pratt Through Truss Bridge in Columbia, Maryland. Built in 1902, it was formerly a B&O Railroad Spur over the Little Patuxent River connecting the town of Savage to the Guilford Quarry. Now, it is part of the Patuxent Branch Trail which runs from Savage Park in Laurel to Lake Elkhorn in Columbia. Dennis DeBruler: Found it: https://maps.app.goo.gl/w7iPptzt1CuPBu5x6 |

| hmdb "History: Railroad expansion in the 19th century required strong, dependable bridges to carry trains over ravines and rivers. Early bridges were built of stone that was sturdy but expensive. Timber bridges often had to be replaced as wood weathered or was burned by hot cinders from steam locomotives. When cast iron, and later wrought iron, came into use, bridges could be built of great strength and longer spans. By the turn of the 20th century, steel had replaced iron for railroad bridges. "In 1844, Caleb and Thomas Pratt developed a bridge that was built with wood and diagonal iron rods. They patented the design, which was made up of sections called trusses. Soon, they built the bridge entirely of iron. This bridge had the advantage of low-cost construction, because the iron parts were made in shops, the parts were easily transported to the site, and the bridge could be quickly erected by semi-skilled labor. It was so popular, it became the standard American truss bridge for moderate spans (from 25 feet to 150 feet), well into the 20th century. "The Pratt Bridge in Guilford is 83 feet long. The distance between the side trusses is 15 feet, 6 inches. It is a single-span structure designed to carry one set of train rails. Instead of crossing the river at right angles, the bridge has a built-in 35-degree left-hand skew. There are inclined end-posts at each end, and pin-connected eye-bars. "This bridge was built in 1902 to carry the Patuxent Branch of the Baltimore and Ohio Railroad over the Little Patuxent River. The train carried heavy loads of granite stone from the Guilford quarries until 1925. The bridge abutments are made from this granite, which was used to construct many other bridge abutments and culverts on the B&O lines. After the railroad spur was abondoned, the bridge surface was planked to serve for a time as a local farm road. "Although hundreds of these bridges were built, only a few survive. Several miles downstream, a similar Pratt bridge, known as the Gabbro Bridge, once carried the quarry train over the Middle Patuxent River. It was washed away by floods. "Long abandoned, the Pratt Through-Truss Bridge was rescued by the Howard County Department of Recreation and Parks and adapted to carry the Patuxent Branch Trail across the river. Its reopening was celebrated with a ribbon cutting on November 2, 2002 - over 100 years after it was built. "Caleb and Thomas Pratt were father-and-son team from Boston. Caleb was an architect, and his son Thomas, born in 1812, became an engineer. By the age of 12, Thomas was preparing plans in his father's office. When he was 14, he attended Rensselaer Polytechnic Institute in Troy NY and then went to work for the railroads designing bridges and other structures. He designed his first truss bridge in 1842; then he and his father were granted a joint patent in 1844 for the Pratt Truss Bridge. When they made the bridge entirely of iron, they pioneered the age of iron railroad bridges." |
