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 58/Old California State Route 178 west of CA 43

This past week I drove California State Route 58 west of CA 43 in Kern County over the Temblor Range and La Panza Range to US Route 101 near Santa Margarita of San Luis Obispo County.


CA 58 west of Bakersfield and CA 99 in general is a mostly two-lane highway that traverses some very remote territory of Central California.  I chose to cover CA 58 west of CA 43 specifically due to the changes in the alignment that are to come when the West Side Parkway connects to the Centennial Corridor project.  The Centennial Corridor will connect CA 58 west of CA 99 to the already completed segment of Freeway on the West Side Parkway.

CA 58 from Barstow west to Bakersfield was carved out of what was US Route 466 during the 1964 State Highway Renumbering.  CA 58 west of Bakersfield to Santa Margarita was carved out of what was part of CA 178.  The change from CA 178 to CA 58 west of Bakersfield to Santa Margarita can be ob…

California State Route 225; the Zombie Highway of Santa Barbara and presently shortest in California

This past month I visited the Santa Barbara Area and drove the many short State Highways located there.  The shortest and the strangest is the 0.081 mile California State Route 225.


As noted above CA 225 is presently only 0.081 miles in length and is located completely on Castillo Street in Santa Barbara between Montecito Street and US 101/CA 1.  Fortunately the Caltrans Post Mile Tool illustrates that CA 225 still exists despite almost being relinquished to death.



At present moment CA 225 is the shortest State Highway in California.  By the definition of actual field mileage the following State Highways are the five shortest in California:

1.  CA 225 at 0.081 miles
2.  CA 275 at 0.14 miles
3.  CA 283 at 0.36 miles
4.  CA 77 at 0.40 miles 
5.  CA 153/CA 265 at 0.50 miles each

The origin of CA 225 was back in 1933 when Legislative Route 150 was added to the State Highway system as a loop of US 101/LRN 2 between Santa Barbara east to near Montecito according to CAhighways.org.  As orig…

California State Route 118

This past month I drove the entirety of California State Route 118 from Ventura County east into Los Angeles County.


CA 118 is a major 47 mile State Highway which begins in the City in Ventura County and traverses east into Los Angeles County by way of Simi Valley and Santa Susana Pass.  From Santa Susana Pass CA 118 continues eastward through San Fernando Valley within the City of Los Angeles and terminates at Interstate 210.  CA 118 contains within it's right-of-way some of the most historic highway corridors in California history.

The precursor route of CA 118 was Legislative Route Number 9 which was first added to the State Highway System during the First State Highway Bond Act of 1909.  The original definition of LRN 9 was from San Bernardino westward to LRN 4 in San Fernando. LRN 9 was extended westward to LRN 2 near Montalvo (modern day Ventura) in 1933.

In a August 1934 Department of Public Works Guide the Signed State Highways were announced.  CA 118 was announced to be a…
