With the wooden bridge over the A1 highway, the Société de livraison des ouvrages olympiques (SOLIDEO) has created the gateway to the 2024 Olympic and Paralympic Games. More precisely – the connection between the media village in Dugny and the sports and school park in Le Bourget. The planning and construction was carried out by the engineering firm Miebach from Lohmar and AIA Life Designers in collaboration with Explorations Architecture. The bridge remains as a permanent crossing and improves the connection to the Parc Georges-Valbon, the third largest green space in Île-de-France.

The 100-meter-long bridge is a special feature in French bridge construction. Wood is rarely used there for large engineering structures. The engineering firm Miebach from Lohmar contributed its expertise to the project and worked together with the French engineering firm AIA Life Designers. Together with Explorations Architecture, they won the competition for the bridge construction in 2020.

The structure consists of a three-span beam bridge with a stepped supporting structure made of block-bonded glulam. The deck was made of precast concrete elements, the railing of architecturally shaped round steel, the handrail is made of steel. A total of around 330 cubic meters of glulam made from French Douglas fir was used.

Despite widespread preconceptions about the durability of wooden bridges, load tests have shown the high resistance of the structure. The bridge was designed to withstand a two-hour fire on the highway below. While steel loses its load-bearing capacity when exposed to heat, wood forms a protective carbonization layer that preserves the inner structure. The architectural design also ensures a high level of structural timber protection. A 30 centimeter protruding concrete edge and beam edges inclined at 30 degrees protect the wood from direct rain.

The design of the bridge is both minimalist and sculptural. The shape is inspired by the minimal art of the artist Carl Andre. Two inclined pillars lend the structure dynamism and make it stand out from the wooded surroundings. The lines in the ground plan and elevation were designed with particular care to create harmonious proportions. Another model for the construction was a wooden bridge in Neckartenzlingen, Swabia, which was also realized by IB Miebach. There, too, the appearance is characterized by an inclined support.

In line with the sustainability goals of the Olympic Games, the bridge was designed with a particular focus on the carbon footprint. The timber construction significantly reduces the carbon footprint compared to conventional materials. The Douglas fir used comes from sustainably managed forests in the Morvan region of France.

Concrete was only used for the foundations, pillars and abutments. A light-coloured road surface minimizes heating from solar radiation, while the intensive planting in the surrounding area reduces the phenomenon of the urban heat island. Excavated material from other Parisian construction projects was also used for the backfill. The total CO₂ footprint of the project is 1100 tons of CO₂ equivalent.

The wooden bridge in Paris is an example of a construction method that takes aesthetic, functional and ecological requirements into account. It connects city districts and improves access to green spaces. The structure demonstrates the possible uses of wood in bridge construction and serves as a reference for sustainable constructions in urban areas.

Discovery of Rembrandt’s “Night Watch”

The team of restorers at the Rijksmuseum in Amsterdam made a sensational discovery. With the help of computer technology, a previously hidden sketch was found on the primed canvas of Rembrandt’s “Night Watch”, the most famous painting in the collection: A sketch that provides a precise insight into the genesis of the work

For two and a half years now, a research team of 30 restorers has been meticulously examining the world-famous painting using imaging techniques and computer technology. Museum visitors can look over their shoulders as they work in a glass box. “The Night Watch” belongs to the city of Amsterdam and has been part of the Rijksmuseum collection since 1808. Frans Banninck Cocq, the mayor and captain of the Citizen’s Guard of Amsterdam, commissioned the group portrait of officers and marksmen, which was completed in 1662.

“The discovery of the sketch is a breakthrough,” emphasizes Taco Dibbits, Director of the Rijksmuseum in Amsterdam. Researchers have long suspected that Rembrandt began his complex composition with a sketch – directly on the brown primed canvas. Later, he only made minor changes. For example, he painted over the feathers originally intended for the helmet of the militiaman Claes van Cruijsbergen. Scans also revealed that Rembrandt altered the position of Rombout Kemp’s legs. Originally, a larger number of spears were also intended in the upper right part of the work.

Looking at Rembrandt with different eyes

“Each new detail gives us further insight into Rembrandt’s creative process, his original idea, his thought processes and his material and artistic choices,” said Petria Noble, head of painting conservation. She is delighted that the varnish on the painting is still in excellent condition. However, some not-so-pleasing discoveries also came to light during the examinations. For example, a series of waves that developed across the painting after it was moved during an earlier renovation in 2003.

It will now be removed from the frame for three months and straightened. The depiction of the dog is also marked by decay. The research team had attributed its discoloration to the fact that the paint was decomposing. Instead, they have now discovered that the wear and tear in this part of the painting has led to greater exposure of the newly discovered bright sketch. “All these discoveries make us look at Rembrandt’s paintings with different eyes,” added Noble. “We now know what to look for.”

Reading tip: “Operation Night Watch” is the title of an ambitious project. In July 2019, a team of restorers began researching and restoring Rembrandt’s “Night Watch”. The artwork, one of the centerpieces of the Amsterdam Rijksmuseum, is to be secured for the future. Read more here.

The mausoleums are falling into disrepair, while the urn fields are expanding

The Cimetière Saint-Pierre is one of the newer cemeteries of its kind: it was established in 1855 and officially inaugurated eight years later. Previously, the people of Marseille buried their loved ones in smaller parish, monastery, or hospital cemeteries—or at the central Saint-Charles Cemetery. Located in the city center, the latter quickly ran out of space and was permanently closed in 1876. Saint-Pierre replaced it, covering an area of 63 hectares.

At first glance, this seems overwhelming. But visitors quickly find their bearings by following the greenery: wherever pine trees grow on small slopes, they are sure to find the historic burial sites. Dozens of renowned French entrepreneurs and artists—including painters, sculptors, and singers—are buried here. Among them is the composer Vincent Scotto. He wished for the following epitaph: “All my life I have composed; today I am decaying.” However, it never came to pass—Scotto’s wife deemed this final wish inappropriate.

Saint-Pierre stands as a striking testament to the changing funeral culture in our neighboring country as well. Extraordinary—and above all, an extraordinary number of—mausoleums, sculptures, and funerary monuments commemorate the cemetery’s heyday—even if some of them are now aging and falling into disrepair in a regrettable state. Huge urn burial grounds down the hillside serve as their modern counterpart.

In total, around 150 employees now work at the cemetery, which contains 100,000 graves. Unusual to German eyes are the cars that, while not numerous, do pass through regularly. Saint-Pierre has a road network totaling 15 kilometers. In Marseille, too, the city administration is working to find solutions for the changing face of cemeteries. Among other initiatives, it has launched grave sponsorship programs and is attempting to catalog as many of the graves as possible in an online database. There is an interactive terminal at the cemetery (and also at the 20 others scattered throughout the city). Interested visitors can use it to search for the graves of famous people—or to find that of a relative on the vast grounds.
