Treasure Island Causeway (Pinellas County Route 150)

By


The Treasure Island Causeway is a crossing of Boca Ciega Bay located in Pinellas County, Florida.  The Treasure Island Causeway connects the city of Treasure Island to St. Petersburg as a component of Pinellas County Route 150.  The Treasure Island Causeway was original completed during 1939 as a tolled facility.  The three current bridges which comprise parts of the larger Treasure Island Causeway were constructed from 2003-2007.  




Part 1; the history of Treasure Island Causeway

The Treasure Island Causeway connects the cities of Treasure Island and St. Petersburg via the waters of Boca Ciega Bay.  The original Treasure Island Causeway opened during 1939 as a continuation of Central Avenue from St. Petersburg to 107th Avenue on Treasure Island.  The original Treasure Island Causeway can be seen on the 1943 United States Geological Survey Maps of Bay Pines and St. Petersburg.  The Treasure Island Causeway can be seen connecting pre-1945 Florida State Road 233 on Treasure Island to Central Avenue in St. Petersburg.  The original Treasure Island Causeway was a tolled structure but was not part of the State Road System.  



The original Treasure Island Causeway can be seen in a series of undated postcards.  




The three bridges comprising the Treasure Island Causeway were deemed to be structurally deficient following an engineering survey during 2002.  The western and eastern bridges of the Treasure Island Causeway were completed by October 2004.  The new central bridge along Treasure Island Causeway was dedicated during August 2007.  The center Treasure Island Causeway bridge is a bascule span measuring 1,014 feet in length.  Upon reopening the Treasure Island Causeway was no longer tolled. 



Part 2; a drive on the Treasure Island Causeway and Pinellas County Route 150

From Florida State Road 699 in Treasure Island the eastbound lanes of the Treasure Island Causeway are accessible from 107th Avenue.  Pinellas County Route 150 is approximately an 8.1-mile highway which is comprised of 107th Avenue, Treasure Island Causeway and Central Avenue to Florida State Road 687 in St. Petersburg.  



Pinellas County Route 150 eastbound transitions from 107th Avenue to the Treasure Island Causeway.  Pinellas County Route 150 crosses the westernmost Treasure Island Causeway bridge to Paradise Island.  Paradise Island is located in the city limits of Treasure Island.  





Pinellas County Route 150 eastbound crosses over Paradise Island and the center bascule span of the Treasure Island Causeway.  Pinellas County Route 150 enters the city of St. Petersburg along Central Avenue upon landing in the Causeway Islands.  The Treasure Island Causeway center bascule span has a vertical clearance of 18 feet above the waters of Boco Ciega Bay when closed.  









Pinellas County Route 150 eastbound crosses the eastern span of the Treasure Island Causeway and intersects Florida State Road 693 at Pasadena Avenue.

Former US Route 50 and the Pioneer Route Lincoln Highway on Johnson's Pass Road

By
Johnson's Pass Road is one of the oldest highway corridors in California.  Johnson's Pass was part of the Lake Tahoe Wagon Road as it was completed during 1856 over the Sierra Nevada.  The pass would later be incorporated into the Pioneer Branch of the Lincoln Highway in 1913 and US Route 50 in 1926.  Johnson's Pass Road would be bypassed by a new alignment of US Route 50 over Echo Summit in 1938.  A replacement of the Meyers Grade east of Johnson's Pass would be opened to traffic in 1947.   Johnson's Pass Road remains accessible to traffic and is still signed by the Lincoln Highway Association.  Pictured as the blog cover is the view from the top of Johnson's Pass Road overlooking modern US Route 50 and Lake Tahoe.   Part 1; the history of Johnson's Pass Much of the history of what become the Lake Tahoe Wagon Road is discussed in the  September 1950 California Highways & Public Works  during its Centennial Edition.  The or...

Former US Route 50 and the South Lincoln Highway from Folsom east to Placerville

By
The corridor of Folsom of Sacramento County east to Placerville of El Dorado County has been a long established corridor of overland travel dating back to the California Gold Rush.  The Folsom-Placerville corridor was once part of the path of the Lake Tahoe Wagon Road which became the first California State Highway and later the South Lincoln Highway.  In time the South Lincoln Highway's surface alignment was inherited by US Route 50.  The Folsom-Placerville corridor also includes the communities of; Clarksville, Shingle Springs and El Dorado. Part 1; the history of the Lake Tahoe Wagon Road, South Lincoln Highway and US Route 50 through Folsom-Placerville Folsom is located on the American River/Lake Natoma of eastern Sacramento County.  That lands now occupied by the City of Folsom were part of Rancho Rio de los Americanos prior to the finding of gold at Sutter's Mill during 1848.  During the California Gold Rush the lands of Rancho Rio de los Americanos were p...

Old NC 10 - The Central Highway: Old Fort to Black Mountain through the Royal Gorge

By
A unique way of tracing the remnants of the Central Highway is through the mountainous terrain of Eastern Buncombe and Western McDowell Counties.  From the east on US 70, you reach the base of Blue Ridge Mountains at the town of Old Fort.  Old Fort is a tiny rail town that the old Central Highway and now US 70 goes through.  The Central Highway can be followed via a right onto Mill Creek Road from US 70.  Follow the highway as it takes you closer to the mountains.  When Mill Creek Road bears right to head towards Andrews Geyser stay straight until the road ends at a gate.  The nearby Piney Grove Church can be used for parking.  At this point, the old Central Highway began a 3.5 mile climb of the mountain to Swannanoa Gap.  NC 10 and later US 70 travelers followed this road for over 30 years until a new and modern four lane US 70 was built to the south.  This same four lane road would eventually become Interstate 40.    The Centra...
