Leadership fixes potholes, not patching.
Chronic neglect of Portland's streets is manifesting in the burgeoning number and size of dangerously large potholes across the city. Here, pothole road damage is seen in Mount Tabor Park, Portland, Oregon.
Engineering: From a technical perspective, a great deal of information can be gleaned from a deep pothole, as it provides a cross-section-view of the pavement structural section, or lack thereof, as in this case. Here, the asphalt wearing surface is heavily pitted, highly oxidized and brittle, confirming many years of neglect. At this pothole, the asphalt layer is thick; confirming this road has received an overlay, but perhaps covering up this pothole without first repairing it. The base course layer is hard to characterize because of the quantity of water present. Roadway base course should be well-graded, faceted aggregate so as to provide optimum particle interlock. This dangerous pothole, in the traveled way and where pedestrians cross, can be repaired by cutting out and reconstructing, but simply patching or overlaying will rapidly lead to a repeat failure, preventing a level of service, or service life, that should be reasonably expected of it.

It sits looking

Looking south towards Michigan / the United States. The International Railroad Bridge was built in 1887 by the Dominion Bridge Company Limited and is an example of a Camelback Truss Span- -a Parker Truss design variation; the bridge consists of nine spans across the St. Mary's River / St. Marys Rapids, and features pinned and riveted connections, a-frame portal bracing, v-lacing support through out, stone abutments and piers. The bridge connects Sault Ste. Marie, Ontario Canada to Sault Ste. Marie, Michigan, United States. The bridge was originally built by the Canadian Pacific Railroad Company and is now owned by the Canadian National Railway Company. Black and white processing alchemy by Nik Silver Efex.

The Falkirk Wheel is a rotating boat lift in Scotland, connecting the Forth and Clyde Canal with the Union Canal. The lift is named after the nearby town of Falkirk in central Scotland. It opened in 2002, reconnecting the two canals for the first time since the 1930s as part of the Millennium Link project.
The plan to regenerate central Scotland's canals and reconnect Glasgow with Edinburghwas led by British Waterways with support and funding from seven local authorities, the Scottish Enterprise Network, the European Regional Development Fund, and the Millennium Commission.
Planners decided early on to create a dramatic 21st-century landmark structure to reconnect the canals, instead of simply recreating the historic lock flight.
The wheel raises boats by 24 metres (79 ft), but the Union Canal is still 11 metres (36 ft) higher than the aqueduct which meets the wheel. Boats must also pass through a pair of locksbetween the top of the wheel and the Union Canal. The Falkirk Wheel is the only rotating boat lift of its kind in the world, and one of two working boat lifts in the United Kingdom, the other being the Anderton boat lift.
The two canals served by the wheel were previously connected by a series of 11 locks. With a 35-metre (115 ft) difference in height, it required 3,500 tonnes (3,400 long tons; 3,900 short tons) of water per run and took most of a day to pass through the flight.
By the 1930s these had fallen into disuse, and the locks were dismantled in 1933.
The Forth and Clyde Canal closed at the end of 1962, and by the mid-1970s the Union Canal was filled in at both ends, rendered impassable by culverts in two places and run in pipes under a housing estate.
The British Waterways Board (BWB) came into existence on 1 January 1963, the day the Forth and Clyde Canal was closed, with the objective of finding a broad strategy for the future of canals in the United Kingdom.
In 1976, the BWB decided after a meeting with local councils that the Forth and Clyde Canal, fragmented by various developments, was to have its remaining navigability preserved by building new bridges with sufficient headroom for boats and continuing to maintain the existing locks.
Restoration of sea-to-sea navigation was deemed too expensive at the time, but there were to be no further restrictions on its use.
MMA 1979 survey report documented 69 obstructions to navigation, and sought the opinions of twenty interested parties to present the Forth and Clyde Local (Subject) Plan in 1980.
The Lotteries Act 1993 resulted in the creation of the Millennium Commission to disseminate funds raised by the sale of lottery tickets for selected "good causes."
In 1996, when sufficient funds had been accumulated, the Commission invited applications to "do anything they thought desirable ... to support worthwhile causes which would mark the year 2000 and the start of the new millennium."The conditions were that the Commission would fund no more than half of the project, with the remaining balance being covered by project backers.
The BWB had made an earlier plan for the reopening of the canal link, which comprehensively covered the necessary work. In 1994, the BWB announced its plan to bid for funding, which was submitted in 1995 on behalf of the Millennium Link Partnership. The plans called for the canals to be opened to their original operating dimensions, with 3 metres (9.8 ft) of headroom above the water. The whole project had a budget of £78 million.
On Valentine's Day 1997, the Commission announced it would support the Link with £32 million of funding, 42% of the project cost.
The Wheel and its associated basin was priced at £17 million, more than a fifth of the total budget.Another £46 million had to be raised in the next two years before construction could commence, with contributions from BWB, seven local councils, Scottish Enterprise, and private donations being augmented by £8.6 million from the European Regional Development Fund.

I love geometric patterns so when I saw all the triangles mirroring the other side, I had to capture it.
For almost a year we have had civil engineering works going on at Dysart shore. Barhale the contractors let a few local residents peer down the deep hole in the harbour car-park, shortly before capping it. Last year they cut a channel out to sea at the far end of Pan Ha' and then installed a 200 metre long, storm-water outflow pipe (see my earlier barge photo). Finally they dug a hole 33 ft (11 metres) wide and 35 feet deep (12.5 metres) through solid sandstones and shale. This was lined at the bottom with 10 feet of concrete and a new deep sewage pipe and filtration system was installed (the man hiding in this shot may give you some idea of the scale). The original car park will shortly be resurfaced and the temporary one dug up and then returfed. Then peace will descend on the beach and harbour again (that is until they begin building the new pier, at the harbour in 2011).

Update. They never did start work on restoring the crumbling harbour Pier. Fife Council's ruling SNP/Lib-Dem coalition withdrew the money that had been earmarked for necessary repairs, thus losing large sums of grant money from the Lottery Fund, Historic Scotland and other bodies, which were linked to the Dysart Regeneration Project. These grants (almost £1 million) have now disappeared forever. When the pier eventually collapses, in the next big storm, closing the harbour forever, I and thousands of Dysart residents will not think kindly of the Scottish Nationalist Party! Our money was used for temporary patching of roads all over Fife and also spent on SNP strongholds in the East Neuk instead?
One of the stranger things about Haven SeaChallenger is that this substantial offshore construction platform is more than half a century old. It was built in Japan by Nippon Steel Corporation in 1974, yet after rebuilding and modernisation it is still earning its keep on some of Britain’s newest and largest infrastructure projects. It has previously carried the names Fugro 1200, Eunsung 1200 and Tsukudo No. 1.
Seen here off Sizewell on the Suffolk coast in August 2026, the vessel is a self-elevating jack-up barge. It floats to its working position like a conventional barge, then lowers its four huge tubular steel legs onto the seabed. The hull can then be jacked upwards, leaving the working deck effectively standing on stilts above the waves. This creates a remarkably stable platform from which heavy cranes, piling machinery and other equipment can work without the vessel rising and falling with the sea.
Haven SeaChallenger measures approximately 50 metres long by 24 metres wide, giving it about 1,200 square metres of deck area. Its four legs are around 55 metres long and 1.8 metres in diameter, while its deck is rated for loads of up to 1,000 tonnes. The legs can be raised or lowered at roughly 30 metres per hour. Despite the rather industrial appearance, it can also provide live-aboard accommodation for crews, allowing offshore work to continue without repeatedly ferrying personnel to and from shore.
The vessel is operated by Red7Marine, the Essex/Suffolk-based specialist marine contractor. The registered owner has been listed as I&C Ltd, trading as Red7Marine. Red7Marine bought the vessel in 2021 as a major expansion of its jack-up fleet, specifically to enable it to undertake larger marine infrastructure, renewable-energy, nuclear, port, coastal-protection and flood-defence projects. The purchase price does not appear to have been publicly disclosed.
This is not simply a floating crane platform. Jack-up barges such as SeaChallenger are useful wherever construction has to take place in shallow or near-shore water. Piles can be driven, sea defences installed, cables landed, foundations built and underwater structures positioned while the barge itself remains almost completely isolated from wave movement. Red7Marine even has specialist piling gates designed specifically for SeaChallenger, including a structure more than 15 metres high used to hold piles accurately while they are installed.
The wider setting in the first photograph is particularly interesting. Behind SeaChallenger stands the unmistakable white dome of the existing Sizewell B nuclear power station, while the enormous construction site for Sizewell C is spreading along the coast immediately beside it.
Sizewell C is being built as a two-reactor 3.2 GW European Pressurised Reactor – EPR – nuclear power station, intended eventually to produce enough electricity for the equivalent of around six million homes. The government gave the project its final investment decision in July 2025 and financial close followed in November that year.
Its scale is extraordinary. The National Audit Office reported in May 2026 that Sizewell C Ltd's current risk-adjusted project baseline was around £38.2 billion in 2024–25 prices, with the station projected to be fully operational by July 2039. A higher regulatory threshold allows for costs of up to approximately £47.7 billion, associated with a later August 2043 completion scenario.
Much of the work taking place offshore is intended to make construction of the power station itself possible. Between about 2025 and 2035, Sizewell C's marine programme includes temporary sea defences, cooling-water intake and outfall structures beneath the seabed, drainage and desalination works, a permanent Beach Landing Facility and a temporary Marine Bulk Import Facility, or MBIF.
The MBIF is essentially a temporary freight jetty extending roughly 500 metres into the North Sea. Large barges will be able to berth alongside it and unload aggregate and other bulk materials directly onto the Sizewell construction site. Around 2.8 million tonnes of material are expected to pass through the facility during construction. Its purpose is to avoid sending all of that material along Suffolk's roads. Sizewell C intends a large proportion of its construction material to arrive by either rail or sea.
SeaChallenger is therefore part of a much wider offshore construction fleet. Other jack-up barges, including Excalibur and NP497, have been working within the Sizewell marine construction zone on piling, drainage, desalination and other offshore structures during 2026. At the peak of marine construction later in the decade, Sizewell C Harbour Authority expects the waters off the site to become exceptionally busy with construction vessels, barges, tugs, survey craft and service boats.
SeaChallenger itself has already had an unusually varied working life. In 2023 it was used to transport an offshore artificial “kittiwake hotel” from Lowestoft, providing nesting space for black-legged kittiwakes displaced by offshore development. In 2024 it was photographed off Weybourne on the north Norfolk coast during offshore cable-related work. It has also been used on projects such as Portland Port's new deep-water berth, where Red7Marine installed 136 steel tubular piles as part of a £3.6 million piling contract.
So although its basic hull dates from 1974, Haven SeaChallenger is now working in a world its original designers could scarcely have imagined: offshore wind farms, environmental mitigation projects and the construction of a new generation of nuclear power stations.
These aerial photographs show particularly clearly how a jack-up barge works. What appear at first to be four giant chimneys are actually its legs. When work is complete at one location the hull is lowered back into the water, the legs are retracted, and the whole platform can be towed away to its next job.
The result is a rather extraordinary combination: a 52-year-old Japanese-built marine platform helping construct one of Britain's most modern and expensive energy projects.

The Centennial Bridge is the second major road crossing of the Panama Canal, the first being the Bridge of the Americas. (Small service bridges are built in the lock structures at Miraflores and Gatún Locks, but these bridges are only usable when the lock gates are closed and have limited capacity.)
The Centennial Bridge is located 15 km (9.3 mi) north of the Bridge of the Americas and crosses the Culebra Cut (Gaillard Cut) close to the Pedro Miguel locks. New freeway sections, connecting Arraijan in the west to Cerro Patacon in the east via the bridge, significantly alleviate congestion on the Bridge of the Americas.
The Bridge of the Americas (Spanish: Puente de las Américas; originally known as the Thatcher Ferry Bridge) is a road bridge in Panama, which spans the Pacific entrance to the Panama Canal. Completed in 1962, at a cost of US$20 million, it was the only non-swinging bridge (there are two other bridges, one at the Miraflores locks and one at the Gatun locks) connecting the north and south American land masses until the opening of the Centennial Bridge in 2004. The bridge was designed by Sverdrup & Parcel.[

After more than three quarters of a century, this tower remains one of Chicago's most notable and remarkable architectural monument. This building was the product of an organized competition for the 'most beautiful and eye-catching building in the world' -- organized by the Chicago Daily Tribune. With its familiar gothic design, and coming up with a building that was more practical for the newspaper company -- it was John Howell's who got the first place award. John Howell would later build another iconic building too -- in New York -- the Rockfeller Center.
This building stands at 141 meters. Located at North Michigan Avenue, overllooking part of the Chicago River. It has been noted that this tower contains interesting stones included in its wall -- rock fragments of Rome's Colosseum and China's great wall. The building also has on display(not included in the walls), one of the many rocks taken from the moon.
