Spanning History: Main Avenue Bridge Recognized

October 6, 2021
 / 
Written by

On Wednesday, October 6, 2021, 82 years from the day when it was opened, the Main Avenue Bridge, also called the Main Avenue Viaduct, will receive a National Historic Civil Engineering Landmark Designation from the Cleveland Section of the American Society of Civil Engineers. According to WEWS TV-5, fewer than 230 projects in the United States have received this distinction.

Built in 1939 with funds allocated from the Public Works Administration, the Main Avenue Bridge was one of many bridges and structures built in Cleveland during the Great Depression as a way to spur economic growth. The span over the Cuyahoga River in the Flats originally featured a float bridge, but was replaced with a 200-foot hand-operated swing bridge in 1869. In 1938, plans to build a new bridge to alleviate the increased traffic driving into the city was introduced by joining the east portion of the Cleveland Memorial Shoreway (named for the local veterans of World War II) to the west side span that extended to Edgewater Park. The eastern portion was originally built in 1936 to access the Great Lakes Exposition, which extended from E. 9th Street to E. 55th. It was the largest project of the Works Project Administration in the country.

When the bridge was completed, it held the record for the longest elevated structure in Ohio (with a length of 8000 feet) until 2007. The initial construction of the bridge, from 1938 to 1939, had workers use over 24,000 tons of steel and 55,000 cubic yards of concrete to build the cantilever truss crossing.

The structure is being given historic landmark status due to its use of continuous, haunched structural forms which offered greater structural efficiency and improved the aesthetics (the haunches are the vertical support structures under the roadway). It is also a significant example of a deck cantilever structure, which means that a structural member is positioned below the joists to support the weight of the frame. The lakefront ramp includes a plate girder span that holds the record at 271 feet and the overpasses at West 28th Street contain some of the first welded rigid frames. The construction represented a significant engineering achievement of the time.

In 1986, the bridge was renamed the Harold H. Burton Memorial Bridge in honor of the man who served as mayor during its construction and in 2007, the signature blue paint was added to keep the steel portions from deteriorating.

5 Tips to Recycle Responsibly

September 3, 2019

Written by

We all want to do our part to help the Earth, but sometimes we feel we just we don’t know how. Nine out of 10 people said they would recycle if it were “easier.” Here are 5 simple tips to become a recycling regular:

1. Follow City’s Pickup Standards.

Depending where you live, recyclables are either collected in blue plastic bags or loose in bins. Follow the regulations of your City to ensure extra plastic is not wasted. If your City does not require collection in plastic bags, use a bin or cart when taking out or dropping off recycling.

Collecting recyclables in plastic bags can cause issues with the recycling equipment and sorting machines. Plastic bags can get tangled and contaminate sorted recycling bins creating more trouble and waste. Because of this, they can end up in landfills, blow away and clog our waterways, oceans and seas.

Plastic bags, like grocery bags should never be recycled with your recyclables. Collect plastic bags and consider looking into collection programs at local grocery stores and retailers. To find a location accepting drop-offs near you, check out plasticfilmrecycling.org. 

2. Only recycle clean, empty containers.

Rinse out your bottles, jars and cartons before throwing them in the recycling. Remember, that pizza box isn’t recyclable. While it is cardboard, it can never be clean and free of grease and food remnants.

3. Replace bottle lids after cleaning.

Plastic lids can now be recycled but they can’t be recycled alone. Bottle lids that are thrown into recycling alone can be hard to spot and are often lost in the process of sorting. This means they can end up with the trash and head to a landfill. After you empty and clean your containers, make sure to put the caps back on.

4. Don’t mix everything together if you’re unsure.

When recycling, it is important not to “wish cycle”. Wish cycling is a term used to describe when someone puts items in their recycling and is unsure if it’s recyclable or not. This creates more waste and contaminates items that could have been recycled. While it feels good to recycle more items, make sure you only recycle the “core” recycling items at home: cans, cartons, glass bottles and jars, paper and boxes, and plastic bottles and jugs.

5. Research your city’s recycling policies.

If you’re interested in learning more about how you can continue or start recycling correctly, research your City’s website to find out what items are accepted, and the best way to recycle. Each site will address any frequently asked questions you might have on recycling properly where you live. If you live in Cuyahoga County, you can find more information at cuyahogarecycles.org.

Species Highlight: Poison Dart Frog

Poison dart frogs got their moniker from indigenous Central and South Americans using the toxins the animals secrete through their skin on hunting arrows. We talked to aquarist Connor Craig to learn more about some of the Greater Cleveland Aquarium’s newest (and deadliest) residents.

Poison dart frogs can be found in nature in the humid rainforests of Central and South America. Their vivid coloring is a form of protection from would-be predators. “A poison dart frog’s bright color advertises the fact that it’s poisonous, so they don’t get eaten,” says Craig adding that although darts frog come in a variety of hues, their color doesn’t correlate to how poisonous they are.

Their deadly poison comes from the frog’s diet of different small insects like ants, small flies and beetles. In the Aquarium, the poison dart frogs eat fruit flies, pinhead crickets and a vitamin supplement to ensure proper nutrition. “The controlled diet doesn’t allow for the development of the poison for which these animals are known,” says Craig.

The only natural predator of the poison dart frog is the fire-bellied snake (Leimadophis epinephelus), which has developed a resistance to the frog’s poison. However, the biggest problems facing poison dart frogs are related to human activity. “One of the first signs that something is wrong in an ecosystem is if indicator species, such as amphibians, start to decline,” Craig says. “Many species of amphibians are threatened from human activities like deforestation, the pet trade and deteriorating water quality.”

While deadly, imagine if their poison could be used to make someone feel better. Scientists are using the toxins blue poison dart frogs secrete to study how nerves conduct electricity to help them create new human painkillers.

Take a stroll down our Coastal Boardwalk Gallery and you’ll find all sorts of creatures. One of the most interesting that you’ll find in our invertebrate Touch Pool is the decapod crustacean, commonly known as a cleaner shrimp. These shrimp exhibit a cleaning symbiotic relationship with the fish they rid of parasites. Here are 5 facts that I have learned about cleaner shrimp.

You can come see a cleaner shrimp up close and even get a “mini-manicure” when they clean the dead skin from your fingers at the Greater Cleveland Aquarium’s Invertebrate Touch Pool. Nature. It’s a curious thing.

Coral Reefs and Sunscreen

August 11, 2019

What can I do, here in Ohio to help protect the coral reefs thousands of miles away? The answer may surprise you. There are numerous ways YOUR individual actions can either hurt or help coral reefs around the world. One such action is the selection of your sunscreen! The sunscreen you have at home may contain chemicals that are extremely dangerous for coral reefs.

Sunscreens are important to us they help prevent skin damage from the harsh ultraviolet rays of the sun. But, the protection of our skin comes at a cost, a few of the chemicals used in sunscreens have been found to have negative effects on coral reefs.  The ingredient oxybenzone is found in 65% of non-mineral sunscreens and it has recently been discovered to damage coral DNA. Oxybenzone, while thought to be an important ingredient for sunscreen has been found to negatively impact coral reefs across the globe.

In 2005 Dr. Craig Downes and the United States National Park Service were working in collaboration to uncover the cause of coral losses in the U.S. Virgin Islands when they stumbled upon the role sunscreen played in coral death. The tourists, sunbathers, snorkelers and divers lathered in sunscreen and to enjoy turquoise blue waters were introducing chemicals that kill the very corals and damage the ecosystem they are trying to enjoy.

It is estimated that every year swimmers, snorkelers and divers introduce 14,000 tons of sunscreen to coral reefs. This introduction of the harsh chemical components in sunscreen, sea temperature rising and ocean acidification have worked together to create the perfect storm for coral reef destruction. Corals are living animals, not plants, these tiny animals build the foundations of the reef out of limestone. The tiny coral polyps live in large communities and play host to a special alga called zooxanthellae.  The zooxanthellae live inside the coral and share food they produce from photosynthesis in return for their safe housing.

So, what can you do to help the coral reefs?

Consider looking into some of the many “reef safe” sunscreen options and/or avoiding the need for sunscreen by wearing a hat or UV-safe long sleeved shirt and pants to protect your skin.  Alternatively, stay indoors instead of in the sun entirely.  We need to be more aware of the impact of our actions even though they may seem inconsequential.  Some states have begun to regulate the chemical components in sunscreen to help keep their coral reefs healthy.

Do your part and think about what you put on your body and into the ocean and coral reef ecosystem!

Shark Conservation: 4 Ways You Can Help

July 28, 2019
 / 
Written by

Sharks are some of the oldest and most complex organisms in the world and their absence would likely have a huge impact on the ocean ecosystem and our world as we know it.  Today, more than 11,000 sharks are killed by humans per hour due to bycatch, finning and overfishing. With humans killing an estimated 100 million sharks a year, it’s critical that we work to protect them. Here are a few ways you can actively support shark conservation.

Education

One of the best first steps to helping our oceans and animals is to educate ourselves! Research organizations all over the world collect data and information about our effect on the environment. Evaluating their findings leads to discussions and discoveries of ways that we can make a better and more conscious impact on the world.  Sharks4Kids goal is to create a new generation of shark advocates through curriculum, games, and activities that can be accessed on their website.  Some other great places we can learn from include:

Charities/Research Organizations

Supporting local and global organizations making a difference is important too. Support can be in the form of monetary donations that allow scientists to fund research vital to understanding the environment.  It can also be in the form of advocating and sharing the knowledge we get from these organizations with others.  The Shark Research Institute in Princeton, NJ conducts some of the most well-known shark research in the world. With one of the largest collections of data on these animals, the Institute is able to provide credible information to the media and help deter misconceptions about sharks.  Their efforts to help change the image of sharks is revered worldwide. Some other great places to look into include:

Reducing Single-Use Plastic

Reduce, reuse, recycle—one of the best known conservation slogans of all time is still an important and effective way to help cut down on pollution that directly affects sharks. Reducing our reliance on single-use plastic can yield amazing results.  By reducing plastic usage less trash accumulates in the ocean and less sharks and their natural food sources such as sea lions and sea turtles will consume these items.  When we refrain from polluting our waters we can in turn make them cleaner and there will be less of a chance for sharks to  consume plastic which can be harmful.  Ocean 4 Plastic is an organization with a mission to remove plastic from oceans.  Their two largest projects located in Haiti and Bali guarantee one pound of trash removal per $20 donation.  Their website features a live count of how many pounds of trash have been removed from oceans by their projects.  They also host cleanups worldwide and build recycling infrastructure in certain locations. Some other great places that actively do this include:

Shopping Sustainably

Being mindful about where you shop for and what foods you buy can have a greater impact than you might think. For example, the shark fin trade and production of shark fin soup greatly depletes shark populations worldwide. Choosing to shop in places that don’t support or contribute to these issues can help our shark populations grow. The Animal Welfare Institute provides a map showing what restaurants in the United States currently produce shark fin soup.  They implore individuals to call those places and ask them to stop providing any products containing shark fins.

Be Wiser with Water

July 15, 2019
 / 
Written by

When Earth’s surface is 70% water, it’s easy to think that water is abundant. However, this is not the case.

Did you know that less than 1% of the Earth’s water is available to 7.5 billion people? This is because the majority of the Earth’s water is saltwater, leaving freshwater making up only 3%. Most freshwater is unavailable for use because it is trapped in glaciers, stored in the atmosphere and soil, too deep in the earth to attain, or highly polluted.

This leaves very little water to share between so many people. Especially when the average American uses between 80-100 gallons of water each day.

With this in mind, it is important to reconsider how we use water every day. Even as individuals, it is possible to make a big difference by changing our habits. Every drop counts!

Turn off the Faucet

This is the simplest bad habit to break! There’s no need to have the water running when you brush your teeth. You also don’t need to faucet running when you rinse food and dishes. Soak them instead!

Check for Leaks

One drip every second adds up to 5 gallons a day! Check your faucets, shower heads, and toilet for any leaks.

Stick to One Cup

Designate one glass or bottle to drink water from each day. You will avoid have to wash excess glasses

Shorten Your Showers

By shortening your shower by a minute, you can have about 150 gallons of water a month. If you can get your shower time down to 5 minutes, you’ll save 1,000 gallons a month!

 

Opt for the Dishwasher Over Handwashing

Washing dishes by hand results in constant running water. Meanwhile, a dishwasher will use about half the amount of water for the same amount of dishes. Using a dishwasher is less work for you anyways!

Only Do Full Loads

When using the dishwasher or washing machine wait until they are full to run them. This will save your 20 gallons of water per wash! You’ll also waste less soap and detergent.

Repurpose Water

A lot of water is wasted every day when it could easily be used for a different purpose. While waiting for the hot water, collect the cold water and use it to water plants. Collect rainwater to use for the same purpose.

Water is finite, and it is important to conserve this valuable resource. Make it a goal to have as little water flow down the drain as possible. Conserving water takes commitment, but the result is well worth it. You will not only make a huge difference on your water bill, but for the environment as well!
