Blue Water Bridge; east terminus of Interstate 94 and north terminus of Interstate 69

While in the Mid-West this year I crossed the Canadian Border into Ontario via the common terminus of Interstate 69 and Interstate 94 at the Blue Water Bridge over the St. Clair River.


The Blue Water Bridge is a dual structure facility which connects I-69/I-94 in Port Huron, Michigan to King's Highway 402 in Sarnia, Ontario.  The first Blue Water Bridge is a 6,178 foot long cantilever truss design which opened in 1938 and present serves westbound traffic.  The second Blue Water Bridge opened is a 6,109 bowstring arch structure which opened in 1997 serving eastbound traffic.  The Blue Water Bridge is operated by the Michigan Department of Transportation and Canadian based Federal Bridge Corporation.

When the Blue Water Bridge opened initially in 1938 it was served via US 25 by proxy from Pine Grove Avenue in Port Huron.  On the Canadian side the initial highway serving the Blue Water Bridge was King's Highway 40.  In 1953 a newly constructed limited access road known as KH 402 was built from the Blue Water Bridge to KH 40 and KH 7.  This 1956 Michigan State Highway Map shows the routes present around the Blue Water Bridge before the American Interstate system was complete

By 1964 I-94 had been completed to Port Huron and was the first Interstate to use the structure.  In 1982 KH 402 was connected to KH 401 in Central Ontario which increased traffic volumes.  I-69 was completed to Port Huron and the Blue Water Bridge in 1984.  Since 1984 both I-94 and I-69 have had a common terminus point at the Blue Water Bridge.

My approach to the Blue Water Bridge was on I-94 east.  I-94 merges onto I-69 north in Port Huron at Exit 271.


The multiplex of I-69/I-94 is very well signed.  Traffic on I-69 north/I-94 east is quickly advised the last American access point is at M-25 via Exit 27t.  M-25 is part of what was US 25 which was truncated in 1974.






Signage indicates that I-69/I-94 ends before the Blue Water Bridge.  Toll rates from the American side for the Blue Water Bride is $3 dollars American and $4 dollars Canadian.




Traffic on the eastbound span of the Blue Water Bridge has three lanes.  Immediately east of the center span of the eastbound Blue Water Bridge signage welcoming drivers to Canada is present.  Beyond the customs checkpoint on the Canadian side of the Blue Water Bridge is the beginning of KH 402.

California State Route 232

This past month I drove the entirety of California State Route 232 in Ventura County. CA 232 is an approximately 4 miles State Highway aligned on Vineland Avenye which begins near Saticoy at CA 118 and traverses southwest to US Route 101 in Oxnard.  The alignment of CA 232 was first adopted into the State Highway System in 1933 as Legislative Route Number 154 according to CAhighways.org. CAhighways.org on LRN 154 As originally defined LRN 154 was aligned from LRN 9 (future CA 118) southwest to LRN 2/US 101 in El Rio.  This configuration of LRN 154 between CA 118/LRN 9 and US 101/LRN 2 can be seen on the 1935 California Division of Highways Map of Ventura County. 1935 Ventura County Highway Map According to CAhighways.org the route of LRN 154 was extended west from US 101/LRN 2 to US 101A/LRN 60 in 1951.  Unfortunately State Highway Maps do not show this extension due to it being extremely small. During the 1964 State Highway Renumbering LRN 154 was assigned CA 232.  Of n

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

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 purchased by Jose

Legacy of US Route 466 Part 3; Morro Bay to Shandon via Rocky Canyon

Part 3 of the US Route 466 Legacy series consists of the roadways that made up the highway between Morro Bay and Shandon of San Luis Obispo County.  The San Luis Obispo County segment of US Route 466 is notable due to it having been carried via a dirt segment through Rocky Canyon from 1933 to 1958.  Pictured in the cover photo of this blog is former US Route 466 facing westward into Rocky Canyon. Part 1 and Part 2 of the US Route 466 Legacy Series can be found below: Legacy of US Route 466 Part 1; California State Route 46 Legacy of US Route 466 Part 2; Tehachapi to Bakersfield  Part 1; mapping early US Route 466 in San Luis Obispo County As discussed in Part 1 of the US Route 466 Legacy series the western terminus of US Route 466 ("US 466") from it's inception until truncation in the 1965 was located in Morro Bay at California State Route 1 ("CA 1"). US 466 between Morro Bay and Shandon had two two primary alignments through it's history.  The initia
