Angus L. Macdonald Bridge

At 1.3 kilometers (or about 0.84 miles) in length, the Angus L. Macdonald Bridge is one of two bridges crossing over the Halifax Harbour between Halifax, Nova Scotia and Dartmouth, Nova Scotia, with the other bridge being the A. Murray Mackay Bridge. Opened in 1955 and named after former Nova Scotia Premier and Canadian Minister of Defense for Naval Services Angus L. Macdonald, the Macdonald Bridge was the first bridge that crossed Halifax Harbour that was opened to traffic. The Macdonald Bridge was also the subject of the Big Lift, which was only the second time in history that the span of a suspension bridge were replaced while the bridge was open to traffic. Planning began in 2010 for the Big Lift, while construction took place between 2015 and 2017. Similar work occurred on the Lion's Gate Bridge in Vancouver, British Columbia before the project took place on the Macdonald Bridge. At this time, much of the bridge infrastructure is new, leaving only the towers, main cables and anchorages on the suspended spans as original to the bridge.

In 2012, I had a chance to see the Angus L. Macdonald Bridge for myself, both by driving over it and also by taking the Alderney Ferry across the Halifax Harbour.

Horace Wilkinson Bridge (Baton Rouge, LA)

Standing tall across from downtown Baton Rouge, the Horace Wilkinson Bridge carries Interstate 10 across the lower Mississippi River between West Baton Rouge and East Baton Rouge Parishes. Unusually, the bridge is actually named for three separate people; three generations of Horace Wilkinsons who served in the Louisiana State Legislature over a combined period of 54 years. Constructed in the 1960s and opened to traffic in 1968, this is one of the largest steel bridges on the lower Mississippi. It’s also the tallest bridge across the Mississippi, with its roadway reaching 175 ft at the center span. Baton Rouge is the northernmost city on the river where deep-water, ocean-going vessels can operate. As a result, this bridge is the northernmost bridge on the river of truly gigantic proportions. Altogether, the bridge is nearly 2 ½ miles long and its massive truss superstructure is 4,550 ft long with a center main truss span of 1,235 ft. The Horace Wilkinson Bridge is one of the largest

Sunshine Bridge (Donaldsonville, LA)

Located about halfway between Baton Rouge and New Orleans in southern Louisiana, the Sunshine Bridge spans the lower Mississippi River near the city of Donaldsonville as part of the longer Louisiana Highway 70 corridor, which connects Interstate 10 and Airline Highway (US 61) with US 90 in Morgan City. In the years following World War II, the only bridges across the lower Mississippi River in Louisiana were located in the area of the state’s two largest cities – Baton Rouge and New Orleans. Postwar agricultural and industrial development along the river in this region led to the planning of a series of infrastructure projects in southern Louisiana that were aimed at spurring this development and modernization of the Delta region. One of these projects was known as the Acadian Thruway and was developed in the 1950s as a toll road intended to connect greater New Orleans with Lafayette and points west while providing a high-speed bypass of the Baton Rouge metro area. The Thruway, which

Veterans Memorial Bridge (Gramercy, LA)

When we think of the greatest engineering achievements and the greatest bridges of North America, we tend to focus on those located in places familiar to us or those structures that serve the greatest roles in connecting the many peoples and cultures of our continent. Greatness can also be found in the places we least expect to find it and that 'greatness' can unfortunately be overlooked, due in large part to projects that are mostly inconsequential, if not wasteful, to the development and fortunes of the surrounding area. In the aftermath of the George Prince ferry disaster that claimed the lives of 78 people in October 1976 in nearby Luling, LA, the state of Louisiana began the process of gradually phasing out most of its prominent cross-river ferry services, a process that remains a work in progress today. While the Luling-Destrehan Ferry service was eliminated in 1983 upon completion of the nearby Hale Boggs Memorial Bridge, the ferry service at Gramercy, LA in rural St.
