Mackenzie River, NWT

The Mackenzie River (French: Fleuve (de) Mackenzie; Slavey: Deh-Cho [tèh tʃʰò], literally big river; Inuvialuktun: Kuukpak [kuːkpɑk], literally great river) is a river in the Canadian boreal forest. It forms, along with the Slave, Peace, and Finlay, the longest river system in Canada, and includes the second largest drainage basin of any North American river after the Mississippi.

The Mackenzie River flows through a vast, thinly populated region of forest and tundra entirely within the Northwest Territories in Canada, although its many tributaries reach into five other Canadian provinces and territories. The river's main stem is 1,738 kilometres (1,080 mi) long, flowing north-northwest from Great Slave Lake into the Arctic Ocean, where it forms a large delta at its mouth. Its extensive watershed drains about 20 percent of Canada. It is the largest river flowing into the Arctic from North America, and including its tributaries has a total length of 4,241 kilometres (2,635 mi), making it the thirteenth longest river system in the world.

The ultimate source of the Mackenzie River is Thutade Lake, in the Northern Interior of British Columbia. The Mackenzie valley is believed to have been the path taken by prehistoric peoples during the initial human migration from Asia to North America over 10,000 years ago, despite sparse evidence.

The Inuvialuit, Gwich'in and other Indigenous peoples lived along the river for thousands of years. The river provided the major route into Canada's northern interior for early European explorers.

Economic development remains limited along the river. During the 19th century, fur trading became a lucrative business, but this was affected by harsh weather conditions. The discovery of oil at Norman Wells in the 1920s began a period of industrialization in the Mackenzie valley. Metallic minerals have been found along the eastern and southern edges of the basin; these include uranium, gold, lead, and zinc. Agriculture remains prevalent along the south, particularly in the Peace River area. Various tributaries and headwaters of the river have been developed for hydroelectricity production, flood control and irrigation.

The Deh Cho Bridge is a 1.1 km-long (0.68 mi) cable-stayed bridge across a 1.6 km (0.99 mi) span of the Mackenzie River on the Yellowknife Highway (Highway 3) near Fort Providence, Northwest Territories. Construction began in 2008 and was expected to be completed in 2010 but faced delays due to technical and financial difficulties. The bridge officially opened to traffic on November 30, 2012. The bridge replaced the MV Merv Hardie, the ferry in operation at the time of opening, and ice bridge combination used for river crossing.

Deh Cho (lit. "Big River") is the Slavey language name for the Mackenzie River.

On July 2nd 1971 The Erskine bridge was officially opened.

Construction on the project began in April 1967 at a cost of £10.5m, which is the equivalent of almost £150m today.

The bridge was designed by Freeman Fox & Partners for the Erskine Bridge Joint Committee. Dr Oleg Kerensky was the partner in charge and the chief design engineer was Dr William Brown under the supervision of Sir Gilbert Roberts. The piers and foundations were designed by W. A. Fairhurst & Partners. The consultant architect was R. E. Slater.

The central span is 305m (1000ft) flanked by anchor spans of 110m each. The total length including approach spans is 1322m. The aerofoil box-girder deck is supported by fourteen diamond-plan, single-shaft concrete piers at a maximum height of 45m above the river. Two central pylons extend 38m above the level of the deck. A 6x4 cluster of galvanized steel cables passes over the saddle of each pylon in a centralised, single plane.

The dual carriageway has cycle lanes and footpaths with metal safety barriers, renewed in 2012. The underside of the deck carries four water mains pipes and two gas pipes. In 2017 the cables were painted and aluminium lighting columns were installed.

The Bridge was a state-of-the-art infrastructure landmark in Scotland for its time and remains one of the country's most architecturally and technically distinguished bridges of the post-war period and beyond its date of construction. It is the first example of a large-scale cable-stayed bridge in Scotland and is recognised for its structural simplicity, economy of materials and slender appearance.

It was designed and built during a period of substantial development in civil engineering and road infrastructure. It illustrates the aspirations for economic and social progress in Scottish society and is directly associated with the period of ambitious transformation of Scotland's modern infrastructure during the 1960s.

The Erskine Bridge is one of only three road bridges in Scotland with a main span exceeding 300 metres. Its minimalistic single-cable design remains exceptionally rare for large-scale road bridges. On completion, the Erskine Bridge is understood to have had the longest span of this type in the world. The appearance of many bridges on this scale have been altered by later alteration and engineering works. The largely unchanged appearance of the Erskine Bridge contributes to its special interest.

Some of these pics I unearthed are brilliant, my faves are, probably the first person to cross the bridge, no health and safety back then, and the photo with the PS Waverley passing by during construction.

La Paz: Teleferico Adventure

From the central station I took the roja (red) line Teleferico up to the highest point in El Alto, 16 de Julio, since there is a great viewpoint there with La Paz city below and all the snow capped mountains surrounding it. La Paz is just under 3,700m above sea level whereas El Alto is about 4,100m so the gondola ride up definitely made my ears pop. They require masks on the public transit and I had to share the cable car with people on every ride but it’s still the ultimate public transport! I didn’t have any wifi or data once there so I followed directions from a blog I found online to get to the viewpoint. El Alto is definitely a dodgy area, I passed a smoky market that must’ve just closed for the day, crossed a bridge that smelled like piss, and avoided some street dogs as well as dodgy people yelling at me the usual “hey bro, hey you speak English, hey where you from”. It’s so frustrating that so many people do this in South America, and more so that they feel entitled to an actual cordial response or a smile from me like “yes thank you for shouting at me, here is my life story, do you want some money too?” When really they all get ignored and actually deserve to get the middle finger from me too. Approaching the viewpoint there was a police car with two officers which made me feel a little better. It was also deserted around this area except for two ladies sitting in the grass while a fire burned on in a pit beside them. I walked out to the viewpoint, a shoddily constructed railing around a concreted platform with several holes through it large enough to fall through or at least drop a foot into. The pictures however were amazing from here. It was directly under the Teleferico red line so I could see each car passing overhead while I stood there admiring La Paz city. The blog I read had recommended staying for the sunset and then riding back down but as the area was so dodgy I didn’t want to stay there any longer so I headed back down around 4:30pm instead, I had the prime viewing seat for photos of the Cementerio General de La Paz and a little neighbourhood with colourful buildings. The central station was quite cool with a train display and La Paz sign set up for photos so I took some there and then Niki’s caught my eye for dinner. I chose the ribs with chips and coleslaw and also tried a papaya flavoured Fanta. The meal was very average as the pork was super fatty but at least it filled the hole somewhat before buying some water, putting my laundry in with reception, and then going to bed for an early night ready to explore more tomorrow.

On September 4th 1964 the Forth Road bridge was officially opened to the public.

Soldiers of Lowland regiments from the south linked up symbolically with a Highland brigade from the north to mark the opening of the new crossing, which cuts more than an hour off the journey-time by road.

The Forth Road Bridge at the time the fourth longest in the world. The opening of the Forth Road Bridge marked end of the Ferries across the Forth an 800-year-old service.

At its peak, the service was running 40,000 trips a year, carrying 1.5m people. The four ferryboats have been run by 70 men only 30 of whom were be re-employed on the new bridge collecting tolls. Up to 400 men have worked on the bridge sometimes in very dangerous conditions with winds up to 100mph. Seven men lost their lives - others were saved by the terylene safety nets suspended beneath them. It took 39,000 tons of steel, 30,800 miles of wire in the suspension cables, and is 163ft above the river at its highest point. Tragically 7 workers died during the construction, although another source says only 3 died.

53 years later, to the day the official opening of The new Queensferry Crossing takes place today. The structure spans 1.7 miles (2.7km) making it the longest three-tower, cable-stayed bridge in the world. Another record was set when in 2013 they had the largest continuous underwater concrete pour over 14 days the 24-hour non-stop operation successfully poured 16,869 cubic metres of concrete into the water-filled south tower caisson.The building work was also hit by tragedy with the death of one worker..

While we remember the building of these bridges we also remember those who died on three structures that cross the Firth of Forth.
