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.

Interstate 40's Tumultuous Ride Through the Pigeon River Gorge

In the nearly 60 years Interstate 40 has been open to traffic through the Pigeon River Gorge in the mountains of Western North Carolina, it has been troubled by frequent rockslides and damaging flooding, which has seen the over 30-mile stretch through North Carolina and Tennessee closed for months at a time. Most recently, excessive rainfall from Hurricane Helene in September 2024 saw sections of Interstate 40 wash away into a raging Pigeon River. While the physical troubles of Interstate 40 are well known, how I-40 came to be through the area is a tale of its own. Interstate 40 West through Haywood County near mile marker 10. I-40's route through the Pigeon River Gorge dates to local political squabbles in the 1940s and a state highway law written in 1921. A small note appeared in the July 28, 1945, Asheville Times. It read that the North Carolina State Highway Commission had authorized a feasibility study of a "...water-level road down [the] Pigeon River to the Tennessee l

Ghost Town Tuesday; Mannfield, FL and the stairway to Hell

Back in 2015 I went searching the Lecanto Sand Hills for the original Citrus County Seat known as Mannfield.  Unlike Centrailia in Hernando County and Fivay in Pasco County I did find something worth seeing. Mannfield is located in the Lecanto Sand Hill section of Withlacoochee State Forest somewhat east of the intersection of Citrus County Route 491 and Mansfield Road. Mannfield was named after Austin Mann and founded in Hernando County in 1884 before Citrus County Split away.  In 1887 Citrus County was split from northern Hernando County while Pasco County was spun off to the south.  Mannfield was selected as the new Citrus County seat due to it being near the county geographic center.  Reportedly Mannfield had as many as 250 people when it was the County Seat.  The town included various businesses one might include at the time, even a sawmill which was common for the area.  In 1891 Citrus County voted to move it's seat to Inverness which set the stage for the decline of M

The National Road - Pennsylvania - Great Crossings Bridge and Somerfield

West of Addison, US 40 crosses the Youghiogheny River at what once was the town of Somerfield.  When crossing the current modern two lane bridge, you many not realize that it is actually the third to cross the Yough at this site.  The first - a stone arch bridge - was known as the Great Crossings Bridge.  Built in 1818, this three arch bridge was part of the original National Road.  The name Great Crossings comes from the men who forded the Youghiogheny here - George Washington and George Braddock.

The Great Crossings Bridge was located in the town of Somerfield.  Somerfield, originally named Smythfield until 1827, would develop as a result of the National Road.
