Caledonia Bridge - Caledonia, Ontario


The Caledonia Bridge, also known as the Argyle Street Bridge, is the longest rainbow arch bridge in the Province of Ontario. Spanning 700 feet across, the Caledonia Bridge includes an impressive nine arches. Opened to traffic on November 19, 1927, the bridge crosses the scenic Grand River in the Haldimand County town of Caledonia.  Caledonia Bridge was the first, and is now the only nine span bridge in Canada. The arches along the bridge tower over most passing vehicles. King's Highway 6 also once crossed this bridge, before the Caledonia Bypass was opened in 1982.

The site where the current Caledonia Bridge is located has a long history of being the location of a noteworthy bridge. In fact, the existing bridge replaced a large, six arch Whipple Arch truss bridge that was built in 1875 along the old Plank Road between Port Dover and Hamilton. Each of those spans were 105 feet (32 meters) in length. A large brick toll keepers residence was also built near the north end of this bridge. The Caledonia Toll House was also completed in 1875. Built by the Caledonia Town Council, the toll house was constructed to collect tolls to cross the Grand River using Caledonia's old Iron Bridge. While tolls were no longer collected at this bridge after 1890, the toll house is now a private residence, remaining true to its Gothic Victorian architecture. At least one portion of the 1875 bridge in Caledonia collapsed due to overloading by a truck in 1925, which prompted interest in constructing a new bridge, leading to construction of the existing rainbow arch bridge.

Built by the Randolph MacDonald Company of Toronto, Ontario, the bridge was completed in a record 140 working days, a feat both in 1927 and today as well. The existing nine span concrete arch bridge that carries Argyle Street across the Grand River in Caledonia is considered to be a heritage bridge and structure. However, time has taken its toll and the bridge is now posted with weight restrictions for crossing vehicles. This also means that the Caledonia Bridge is not long for this world, as there is a project study in place as of 2019 in order to replace the historic nine arched rainbow arch bridge with a steel arch bridge.

I visited the Caledonia Bridge on two occasions, in 2005 and 2010. This heritage bridge (in Ontario, they use the term heritage instead of historic for these sorts of sites) is truly unique and worth visiting if you happen to be in the area. Here are some photos that I have took of the bridge and its surroundings.

Where the hell is Hill Valley? (US Route 8 south/US Route 395 east)

Recently I made a visit to Universal Studios near Los Angeles.  While on the back lot tour I came across a piece of infamous movie-borne fictional highway infamy; the location of town square of Hill Valley, California on US Route 8/US Route 395. The above photo is part of the intro scene to the first Back-to-the-Future movie which was set in 1985. To anyone who follows roadways the signage error of US 8 meeting US 395 in California is an immediately notable error.  For one; US 8 doesn't even exist anywhere near California with present alignment being signed as an east/west highway between Norway, Michigan and Forest Lake, Minnesota.  To make matters worse US 8 is signed as a southbound route and US 395 (a north/south highway) is signed as an eastbound route.  At minimum the cut-out US 8 and US 395 shields somewhat resemble what Caltrans used in the 1980s. Assuming Hill Valley is located on what would have been US 395 by 1985 what locales would be a viable real world analog? 

The Vague Original Southern Terminus of US Route 91 in the Californian Mojave Desert

One of the more intriguing mysteries of the early US Route System in California is where the original south terminus of US Route 91 was intended to be located in the Mojave Desert.  This blog is a little different than my usual behind the wheel fare and explores why US Route 91 ultimately ended at US Route 66 in Daggett instead of Bannock. What ultimately became the US Route System was first discussed during the American Association of State Highway Officials ("AASHO") during their annual 1924 meeting.  Ultimately the AASHO recommended to the Department of Agriculture to work with the States to develop a system of Interstate Highways to replace the many Auto Trails in use.  The Joint Board on Interstate Highways was ultimately commissioned by the Department of Agriculture and it's branch agency the Bureau of Public Roads in March of 1925.  The Joint Board on Interstate Highways first met in April of 1925 and decided on the new interstate road network would be known a

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.  The Ridge Route is a 44 mile section of highway which was completed in 1915.  The Ridge Route originally stretched from Castaic Junction north over Liebre Summit and Tejon Pass to the tiny community of Grapevine.  In spite of a roadway that once utilized nearly 700 curves the Ridge Route is generally considered far ahead of it's time and one of the first modern highways constructed for automotive use.
