According to Iamaccepted, US 45 is a US Highway in the US state of Michigan. The road forms a north-south route in the west of the so-called “Upper Peninsula”, the northern peninsula and runs from the Wisconsin border to Ontonagon on Lake Superior. The route is 90 kilometers long.

Travel directions

South of Watersmeet, US 45 in Wisconsin enters the state of Michigan, from the Milwaukee region. The road then heads north through wooded areas and soon reaches the intersection with US 2, the road from Ironwood to Iron Mountain. It then passes through the Ottawa National Forest and the road crosses several State Routes, which supplement the US Highway system in the state. The road then heads to Ontonagon, a small town at the mouth of the river of the same name in Lake Superior.


US 45 was created in 1926, but its northern terminus was initially at Des Plaines near Chicago, Illinois. In 1935, the route was extended north through Wisconsin and Michigan to Ontonagon on Lake Superior. The US 45 is only of regional importance and therefore not developed to a high standard.

Traffic intensities

The road is very quiet, the southernmost section is the busiest with 2,500 vehicles, but only 880 vehicles drive to Ontonagon.

Travel directions

The US 8 in Minnesota.

US 8 is one of the most secondary main routes of the US Highways, and is almost everywhere a two-lane road that also does not serve any larger place. US 8 begins in Forest Lake on Interstate 35 in Minnesota and ends in Norway on US 2 in Michigan. The route crosses northern Wisconsin and only visits a few small towns, Rhinelander being the most important. A number of rivers are crossed, such as the St. Croix, the Chippewa and the Wisconsin.


US 8 was created in 1926 and ran from Wyoming, Minnesota to Powers, Michigan at the time. In 1927 the route was already shortened to Iron Mountain in Michigan and in 1929 further to Norway. In Minnesota, the route was shortened to the city of Minneapolis in 1931 and with the completion of I-35 in 1981 to Forest Lake, making US 8 mostly in the state of Wisconsin.

According to ACRONYMMONSTER, the Ambassador Bridge is a suspension bridge in the United States and Canada, located near the city of Detroit.


The Ambassador Bridge spans the Detroit River, which forms the border between the United States and Canada. The state of Michigan with the city of Detroit is located on the north bank, and the Canadian province of Ontario with the city of Windsor on the south bank. The Ambassador Bridge is a four -lane suspension bridge with a total span of 2,286 meters and a main span of 564 meters. The free passage under the bridge is 46 meters. An unnumbered road runs across the bridge from Interstate 75 in Michiganto Ontario Provincial Highway 3. On the American side the bridge connects directly to the highway, on the Canadian side traffic has to go straight through Windsor. The bridge is a toll road.


The bridge was built between 1927 and 1929 according to a design by engineer Ralph Modjeski and opened to traffic on November 11, 1929. It was the longest suspension bridge in the world until the George Washington Bridge in New York was opened in 1931. A year after the Ambassador Bridge opened, the nearby 2-lane Detroit–Windsor Tunnel opened to traffic. The bridge has changed little since it opened. 80 years after opening, in 2009, the interchange with I-75 in Detroit was built.


It is planned to increase the capacity of the connections between Detroit and Canada. Capacity between the two countries at Detroit has remained the same since 1930. One problem is mainly the amount of freight traffic that has to drive through Windsor to reach the bridge. The owner of the Ambassador Bridge wants to build a parallel cable- stayed bridge under its own management, but the US government prefers a new connection further south, which connects directly to highways on both the American and Canadian sides. The Ambassador Bridge owner is not happy with this plan because it has a virtual monopoly on cross-border traffic and is afraid of losing toll revenue. The new bridge went under construction in 2018 and is known as theGordie Howe International Bridge.

Traffic intensities

In 2010, 19,800 vehicles drove over the Ambassador Bridge every day, more than half of which were freight traffic. The bridge is by far the busiest heavy truck connection between Canada and the United States with 1.5 million trucks per year. This is 50% more than at Buffalo and double the alternative border crossing at Port Huron/Sarnia.


The bridge is a toll road, tolls are collected in both directions and are $5.00 in both US and Canadian dollars.

The Blue Water Bridge are two parallel bridges on the border of Canada and the United States, located at Port Huron and Sarnia.


The bridge consists of two spans. The northern bridge for traffic to the United States is a 1,862-meter truss bridge with a main span of 265 meters. The bridge deck is 46 meters above the St. Clair River and is 12 meters wide. The bridge has 3 lanes and no emergency lanes.

The southern bridge is an arch bridge totaling 1,862 meters with a main span of 281 meters. The bridge deck is 47 meters above the water. The bridge deck is 16 meters wide, with 3 lanes and an emergency lane.

On the Canadian side, Highway 402 connects in Ontario, which runs east to London. On the US side, Interstate 69 in Michigan connects to Lansing and Interstate 94 in Michigan to Detroit.


The first bridge was the truss bridge, which was designed by the famous Polish-American engineer Ralph Modjeski. This bridge opened to traffic on October 10, 1938. The bridge originally had 1×2 lanes with footpaths, but was converted to 3 lanes in the 1980s. In 1964, the I-69/I-94 connected to the bridge on the American side. In 1982, Highway 402 in Canada joined the bridge. A second span was built between 1995 and 1997 to increase capacity. The second arch bridge opened to traffic on July 22, 1997. In 2012, the connecting Highway 402 in Sarnia was widened. In 2015, the bridge deck of the northern span was renovated.

Traffic intensities

14,000 vehicles cross the bridge every day.


The bridge is a toll road. Tolls are charged in both directions.
