Powerscourt Covered Bridge

The Powerscourt Covered Bridge, also known as the Percy Covered Bridge, is Canada's oldest covered bridge. Not only is it the oldest covered bridge in Canada, it is the only known example of a McCallum inflexible arched truss bridge still in existence. The covered bridge was built in 1861 over the Chateauguay River on First Concession Road near Hinchinbrooke, Quebec, just north of the border with New York State. The Powerscourt Covered Bridge is the only non-railroad bridge in the world using the McCallum inflexible arched truss design. This design was developed by Daniel McCallum, who was an engineer for the New York and Erie Railroad, and superintendent of railroads for the Union side in the Civil War. The techniques in building the two span Powerscourt Covered Bridge was otherwise used exclusively in the construction of railroad bridges. Because of the Powerscourt Covered Bridge's unique place in history, it was designated a National Historic Site in 1984 and the bridge was restored in 2009.

In this southwestern corner of Quebec between the border with New York and the St. Lawrence River, you will find an unique blend of French and English heritage. English Loyalists settled there after the Revolutionary War and some French Canadians decided to settle across the border in New York to farm. If you look at a map, you will find names like Huntingdon, Elgin, Hinchinbrooke and Hemmingford among the towns that dot this part of Quebec. As for nearby Powerscourt, it was once a much busier place, but today, there are just a few houses, a church building and a sturdy reminder of this region's past, present and future, the Powerscourt Covered Bridge.

Yes, the color of your nearby fire hydrant matters...

...and here's why. You will find White, Red, Yellow and Violet colored fire hydrants pretty much everywhere.  But there's a reason for this - and it's because of the National Fire Protection Association (NFPA).  This association has issued guidelines for color coding standards for fire hydrants.  These color codes from the body of the hydrant, top of the hydrant, and in some municipalities the outlet caps are designed to allow fire fighters to know what type of system, water flow rate (Gallons Per Minute or GPM), and level of water pressure.  This guideline is known as NFPA 291 and is intended to be used universally throughout the United States. The NFPA guidelines are specific to the body and the top cap of the hydrant.  If a hydrant is WHITE or YELLOW - it means that it is connected to a public/municipal water system.  If a hydrant is RED - the hydrant is connected to a private system, typically a well.  These are most common in rural or unincorporated areas

Legend of the Ridge Route; a history of crossing the mountains between the Los Angeles Basin and San Joaquin Valley from wagon trails to Interstates

Over the past two decades I've crossed the Interstate 5 corridor from Los Angeles north over the Sierra Pelona Mountains and Tehachapi Range to San Joaquin Valley what seems to be an immeasurable number of times.  While Interstate 5 from Castaic Junction to Grapevine via Tejon Pass today is known to most as "The Grapevine" it occupies a corridor which has been traversed by numerous historic highways.  The most notable of these highways is known as the "Ridge Route."  This article is dedicated to the Ridge Route and the various highways that preceded it.  This blog is part of the larger Gribblenation US Route 99 Page.  For more information pertaining to the other various segments of US Route 99 and it's three-digit child routes check out the link the below.

Establishing the numbering conventions of California's chargeable Interstates

The Federal Highway Aid Act of 1956 brought the Interstate Highway System into existence which would largely be constructed by Federal Highway Administration fund matching.  The Interstate Highway System was deliberately numbered to run opposite the established conventions of the US Route System.  While the Interstate Highway numbering conventions are now well established there was a period during the late 1950s where they were still being finalized.  This blog examines the history of the establishing of the chargeable Interstate Highway route numbers in California.  The above blog cover depicts the Interstate Highway route numbers requested by the Division of Highways in the Los Angeles area during November 1957.  The establishment of the numbering conventions of California's chargeable Interstates The Interstate Highway System was not created in a vacuum by way of the passage of the 1956 Federal Highway Aid Act.  The beginning of the Interstate Highway System can be found in the
