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.

Hidden California State Route 710 and the Pasadena Gap in the Long Beach Freeway

Infamous and the subject of much controversy the Pasadena Gap in the Long Beach Freeway has long existed as a contentious topic regarding the completion of Interstate 710 and California State Route 710.  While the Pasadena Gap of the Long Beach Freeway effectively has been legislatively blocked the action only came after decades of controversy.  While the Pasadena Gap of the Long Beach Freeway is fairly well known what many don't know is that a small segment was actually constructed south Interstate 210 and the Foothill Freeway.  This disconnected segment of the Long Beach Freeway exists as the unsigned and largely hidden California State Route 710.  On June 29, 2022 the California Transportation Commission relinquished California State Route 710 to the city of Pasadena.  The blog cover above depicts a southward view on the completed Pasadena stub segment of the Long Beach Freeway which ends at California Boulevard.   Part 1; the history of the Pasadena Gap of the Long Beach Freewa

Deer Isle Bridge in Maine

As graceful a bridge that I ever set my eyes upon, the Deer Isle Bridge (officially known as the Deer Isle-Sedgwick Bridge) surprisingly caught my eye as I was driving around coastal Maine one Saturday afternoon. About 35 miles south of Bangor, Maine , the Deer Isle Bridge connects the Blue Hill Peninsula of Downeast Maine with Little Deer Isle over the Eggemoggin Reach on ME 15 between the towns of Sedgwick and Deer Isle . It should be noted that Little Deer Isle is connected to Deer Isle by way of a boulder lined causeway, and there is a storied regatta that takes place on the Eggemoggin Reach each summer. But the Deer Isle Bridge holds many stories, not just for the vacationers who spend part of their summer on Deer Isle or in nearby Stonington , but for the residents throughout the years and the folks who have had a hand bringing this vital link to life.   The Deer Isle Bridge was designed by David Steinman and built by the Phoenix Bridge Company of Phoenixville,

Paper Highways: Proposed US Route 66 Alternate to Las Vegas, Nevada

During February 1956 the State of Nevada in concurrence with the States of California and Arizona submitted a request to the American Association of State Highway Officials to establish US Route 66 Alternate to Las Vegas.  The proposed US Route 66 Alternate would have originated from mainline US Route 66 in Kingman Arizona and followed a multiplex of US Routes 93-466 to Las Vegas, Nevada.  From Las Vegas, Nevada the proposed US Route 66 Alternate would have multiplexed US Routes 91-466 back to mainline US Route 66 in Barstow, California.  The request to establish US Route 66 Alternate was denied during June 1956 due to it being completely multiplexed with other US Routes.  This blog will examine the timeline of the US Route 66 Alternate proposal to Las Vegas, Nevada. The history of the proposed US Route 66 Alternate to Las Vegas, Nevada On February 15, 1956, the Nevada State Highway Engineer in a letter to the American Association of State Highways Officials (AASHO) advising that six c
