General Sullivan Bridge



Named for famed Revolutionary War General John Sullivan, the General Sullivan Bridge is a grand old bridge which graces the Great Bay of the Piscataqua River between Dover and Newington in New Hampshire's Seacoast region, not far from Portsmouth. Built in 1934, the 1,585 foot long continuous truss bridge is the longest existing pre-1940 bridge in New Hampshire and was similar in design to the old Lake Champlain Bridge between Vermont and New York State. The General Sullivan Bridge was a trailblazer. Designed by Fay, Spofford and Thorndike, a nationally recognized bridge engineering firms of the time, the continuous truss form advanced the design and construction methods of its day and it is attributed to the influence of future highway bridges that use similar structural principles and configuration.

In the vicinity of the General Sullivan Bridge was one of the earliest water crossings in New Hampshire. Over time, and as automobile traffic increased, the roads approaching the crossing became part of the first set of state highways in New Hampshire, which now follow the US 4 and NH 16 corridors. The General Sullivan Bridge carried traffic across Little Bay for more than 30 years until traffic demands along the Spaulding Turnpike required more capacity and the Little Bay Bridge was constructed and opened in 1966. The General Sullivan Bridge continued to carry southbound traffic until 1984 when the Little Bay Bridge was widened and all turnpike traffic was routed on to the newer bridges. Since that time, the General Sullivan Bridge has been a bicycle and pedestrian crossing and a location for anglers who enjoy fishing in the Great Bay below.

However, the General Sullivan Bridge may not be long for this world. In 2010 and 2015, fencing was installed along the deck to limit access to the middle part of the deck based on the bridge's deterioration. In 2017, the New Hampshire Department of Transportation determined the General Sullivan “was not rehab safe,” and in 2018 it was closed to even pedestrian and bike travel. NHDOT had planned to rehabilitate the General Sullivan Bridge as part of the Spaulding Turnpike expansion project, but in 2018, NHDOT officials acknowledged it would be much cheaper to replace the bridge than rehabilitate it. Officials estimated it would save $16.3 million to take down and rebuild the bridge rather than repairing it, while also saving $44.3 million in maintenance costs over the expected 75 year life of the bridge. There is an historic nature to the old bridge, as in 1988, the bridge was deemed eligible for National Register of Historic Places consideration. So if the bridge is torn down, some historic artifacts related to the old bridge may be kept and displayed.

In 2013, I made a couple of trips to the New Hampshire Seacoast region to explore the General Sullivan Bridge. This was in preparation for the Portsmouth road meet that I hosted during 2013. Naturally, I took a number of photos for your enjoyment.

Ghost Town Tuesday; Vineland, Florida; the town killed by Disney

Vineland is a small ghost town located in southwest Orange County, Florida near the junction of Florida State Road 535 and Interstate 4.  Vineland is somewhat unique due to it largely being squeezed out of existence by Lake Buena Vista which is the company town where Disney World is located. Vineland was founded in the late 1800s as Englewood.  The town name of Englewood changed to Orange Center in 1911 before finally assuming the name Vineland in 1924.  Much like the rest of Orange County the community of Vineland was centered around Citrus Grove.  In the case of Vineland said orange groves were centered around Ruby Lake. The end of Vineland came as the Disney Corporation began purchasing parcels of citrus grove land to build Lake Buena Vista.  Vineland fell into a sharp decline in the 1960s but the community managed to continue to exist to modern times.  Much of the street grid of Vineland still exists east of FL 535 but most of the original structures are either gone or falle

Old NY 10 and Goodman Mountain in the Adirondacks

  Old highway alignments come in all shapes and sizes, as well as taking some different forms after their lifespan of serving cars and trucks has ended. In the case of an old alignment of what was NY 10 south of Tupper Lake, New York, part of the old road was turned into part of a hiking trail to go up Goodman Mountain. At one time, the road passed by Goodman Mountain to the east, or Litchfield Mountain as it was known at the time. As the years passed, sometime around 1960, the part of NY 10 north of Speculator became part of NY 30, and remains that way today from Speculator, past Indian Lake and Tupper Lake and up to the Canadian Border. At one time, the highway was realigned to pass the Goodman Mountain to the west, leaving this stretch of road to be mostly forgotten and to be reclaimed by nature. During the summer of 2014, a 1.6 mile long hiking trail was approved the Adirondack Park Agency to be constructed to the summit of the 2,176 foot high Goodman Mountain. For the first 0.9 mi

Oregon State Highway 58

  Also known as the Willamette Highway No. 18, the route of Oregon State Highway 58 (OR 58) stretches some 86 miles between US 97 north of Chemult and I-5 just outside of Eugene, Oregon. A main route between the Willamette Valley region of Oregon with Central Oregon and Crater Lake National Park, the highway follows the Middle Fork Willamette River and Salt Creek for much of its route as it makes its way to and across the Cascades, cresting at 5,138 feet above sea level at Willamette Pass. That is a gain of over 4,500 in elevation from where the highway begins at I-5. The upper reaches of OR 58 are dominated by the principal pinnacle that can sometimes be seen from the highway, Diamond Peak, and three nearby lakes, Crescent, Odell and Waldo (Oregon's second largest lake). OR 58 is chock full of rivers, creeks, mountain views, hot springs and waterfalls within a short distance from the highway. OR 58 was numbered as such by the Oregon State Highway Department in 1940. OR 58 is a del
