Fixing cracks and potholes in concrete roads like this one may be easier with help from bacteria.
Patching concrete sidewalks, roads and bridges after every season of snow and ice is expensive. A team of engineers is now testing a new approach harnessing bacteria to patch the potholes and cracks.
Miami is investing hundreds of millions of dollars to raise roads in response to rising sea levels.

Infrastructure systems – roads, water treatment systems, power grid – can't be built the same ways as in the past. What's a better roadmap for the future?
At 90 years old, the Tyne Bridge shows how a practical piece of infrastructure can become an integral part of a city's culture and identity.
There are more than 50,000 public bridges in Australia. (The Sea Cliff bridge is one Australia’s newer bridges, built in 2005).
Australian bridges are generally safe, but we don't have transparent information about how often they're inspected or maintained.
The Ponte Morandi bridge, Genoa, after its collapse, which has claimed dozens of lives.
Bridge engineering does not end when construction finishes and traffic starts to flow.
We'd need some major innovation to bridge the Channel without disrupting shipping.

Congressional inability to devise a health care plan for the US is not the only impediment to good health care. Contaminated water pipes and old bridges are also roadblocks.
What could be better?

In a busy city like London, green space is a valuable commodity.
Instead of trying to maintain our usual routines in the face of huge disruptions, we should use them as a welcome opportunity to mix things up.
Some US bridges are currently living out their twilight years.
There are about 600,000 bridges in the United States, and about one in four is classified as functionally obsolete or structurally deficient. This doesn’t mean they’re in danger of imminent collapse; they…
The most recent bridge collapse in Washington was due to an oversize truck collision.
Bridge collapses are often tragic, but are also fascinating for bridge engineers as they usually provide puzzles to solve and often lead to major changes in design, construction and management. Complete…
