Ambassador Bridge

While on a recent trip through Ontario I returned to the United States via the Ambassador Bridge.


The Ambassador Bridge connects King's Highway 3 in Windsor, Ontario to Interstates 75 and 96 in Detroit, Michigan.  The Ambassador Bridge crosses the Detroit River which serves as the International Boundary between Canada and the United States.  The Ambassador Bridge is the busiest trade crossing between Canada and the United States carrying close to a quarter of freight between the two countries.

The first study to construct a bridge over the Detroit River was ordered by the United States Congress in 1889 but ultimately was not approved.   Plans to build a bridge over the Detroit River weren't revisited until 1919 which ultimately resulted in construction of the Ambassador Bridge beginning in August of 1927.  The Ambassador Bridge opened to traffic in November of 1929.

The Ambassador Bridge is a suspension design which carries four lanes of undivided traffic.  The Ambassador Bridge is 7,500 feet in length with the longest span being 1,850 feet in length.  The maximum clearance beneath the roadway to the Detroit River is 152 feet.  The Ambassador Bridge is presently owned/maintained by the Detroit International Bridge Company and Canadian Transit Company.  The private ownership of the Ambassador Bridge has been contentious which is a far longer story than I'm willing to go into in a blog post.

My approach to the Ambassador Bridge was from King's Highway 3 on Church Huron Road from King's Highway 401.




Traffic on the Ambassador Bridge is directed to stay on KH 3.


At College Avenue the westbound approach for the Ambassador Bridge begins.


Traffic onto the Ambassador Bridge is routed around the Canadian Customs Station.






The Ambassador Bridge begins to climb over the Detroit River.  Both support spans display a large sign stating "Ambassador Bridge."








From the central span of the Ambassador Bridge heading westbound the skyline of downtown Detroit can be seen.


The Ambassador Bridge crosses over the Detroit River into the City of Detroit.








Cars are directed to stay left approaching the U.S. Customs Station.  Approaching the Custom Station the Michigan Central Station can be seen off the to the right.





As of September 2012 the Ambassador Bridge directly accesses I-75 and I-96.


Originally the Ambassador Bridge in Detroit was accessed from Porter Street between 21st and 22nd Streets.  The original access configuration of the Ambassador Bridge can been seen on this 1956 Rand McNally map of downtown Detroit.

I don't have a ton of pictures of the Ambassador Bridge but for what it's worth this one is from Belle Isle in 2015 during a rain storm.

California State Route 190; a Trans-Sierra Highway that could have been

This past week I decided to take a small scale road trip on California State Route 190 from CA 99 east to the unbuilt section over the Sierra Nevada Range.  While I was in for what turned out to be a fun drive following the course of the Tule River watershed what I found researching the back story of CA 190 was one of the most complex and unusual stories of any California State Highway.  Given that I had a ton of older photos of the eastern segment of CA 190 in the Mojave Desert of Inyo County I thought it was time to put something together for the entire route. The simplified story of CA 190 is that it is a 231 mile state highway that has a 43 mile unbuilt gap in the Sierra Nevada Range.  CA 190 is an east/west State Highway running from CA 99 in Tulare County at Tipton east to CA 127 located in Death Valley Junction near the Nevada State Line in rural Inyo County.  The routing CA 190 was adopted into the State Highway system as Legislative Route 127 which was adopted in 1933 acc

I-73/I-74 and NC Future Interstates, Year in Review 2022

Another year over, already? 2022 turned out to be quite the year if you are a fan of new interstate routes, and it wasn't bad for some long standing favorites. As per the tradition, I will review what happened with I-73 and I-74, and then the other new and future interstate routes in North Carolina... Work continued on the one segment of I-73 under construction, the I-73/I-74 Rockingham Bypass. As of the beginning of December, work was getting close to being 2/3 complete at 60.1%. Progress could be seen from US 74 on constructing of the future interchange at the Bypass's southern end. Here's a look from US 74 East in September from Google Maps Street View: Here's a photo from US 74 West taken last week by David Gallo: Work is now scheduled to be completed in October 2025, though the road itself could open earlier that year.  Progress on I-74 earned more publicity in 2022 with the opening of 7.5 more miles of the Winston-Salem Northern Beltway from US 311 (Exit 49) to NC

Interstate 605

Interstate 605 is a 27.4-mile freeway located in the Los Angeles Metropolitain Area.  Interstate 605 begins at Interstate 210 near Duarte and terminates at the Interstate 405/California State Route 22 junction to the south near the boundary to the city of Long Beach.  Interstate 605 is known as the San Gabriel River Freeway and has three unconstructed miles which would extend it south to California State Route 1 near Seal Beach.  Much of the corridor of Interstate 605 was built up from what was the original California State Route 35.  The blog cover photo is taken from the July/August 1964 California Highways & Public Works which featured the initial segment of Interstate 605 to open between Whittier Boulevard and Peck Road  Part 1; the history of the San Gabriel River Freeway and Interstate 605 The origin of what is now Interstate 605 begins during 1933 with the addition of Legislative Route Number 170 (LRN 170) to the State Highway System.  The original definition of LRN 170 was
